Characteristics of the Titrator TitroLine KF trace
1.1 General Information
Nonwarranty Clause
The measuring or analysis results depend on many factors. Please check the measuring and/or analysis
results regularly for plausibility and carry out appropriate reliability tests. Please mind all common
validation procedures too.
The titrator TitroLine KF trace is a very complex and completely coulometric titrator used to measure the
humidity ratio according to Karl-Fischer.
The titrator’s operability allows you to work in an uncomplicated way. The display asks you to select the
respective functions and/or to set the respective parameters. The titrator’s display shows you the actual
status even during the operation sequence.
The methods for sample titrations and the collection of blank values are already pre-assigned. Thus, it is
possible to start the titration directly after installation. Normally, it is not necessary to change the titration
parameters.
Almost all parts are already pre-assembled. Thus, the measuring place can easily be installed within
minutes.
Due to the connection of a PC-keyboard, e.g. TZ 2835, it is easier to weight samples and to enter
alphabetical sample designations.
1.2 Reagents
Solutions to be used:
All common and modern Karl-Fischer reagents can be used for the coulometry process.
There is a general rule:
It is strictly necessary to mind all valid safety guidelines for chemical products. This applies particularly to
inflammable and/or caustic liquids.

63
Fill the KF Anolyte into the brown 1 l-reagent bottle. You can also connect the GL 45 adaptor directly
to the anolyte bottle if it has a GL-45 –thread. It is also possible to use other reagent bottles with a
GL 45 thread or a S 40 thread (adaptor TZ 1795) instead of the provided square laboratory bottle.
Power Supply of the Titration Stand TM KF
The titrator stand is energised via the titrator. Connect the titration stand and the titrator with the provided
low voltage cable TZ 1577. Please use the upper connection socket at the magnetic stirrer/TMKF. The
socket on the titrator is to be found directly below the USB-port. (See
Fig. 16).
Working with the titration stand
• Dosage: Pump the anolyte into the titration vessel by pressing the front part of the rocker switch. As
long as you press the button the dosing process proceeds.
• Siphon off: Siphon off the solution from the titration vessel by pressing the back part of the rocker
switch. As long as you press the button it will be siphoned off.
Note:
Mind the fill level of the waste bottle. Before you siphon off the titrating solution please make
sure that the disposal bottle can absorb this amount of solution.
The built-in magnetic stirrer stirs the liquids in the titration vessel. You can adjust the stirring speed at the
turning knob at the front side of the titration stand ( Fig. 19).
Fig.19
Troubles
Problems might occur if the tubes are not connected properly or the pressure / low pressure system has a
leakage. Then, after a few seconds operating time of the pump, no reagents will be conveyed anymore.
When checking the tubes please observe that the bottle screwing and all adaptors are leak-proof. The
same applies to the tube connections of the drying bottle.
Note:
Buckled tubes cause incorrect dosages and also the siphon off process does not work properly.
Please check the tubes and their connections for leak-tightness on a regular basis. Replace if
necessary.
If the reagents continue to run in from the storage bottle after the actual dosage process has ended,
position the bottle at lower level than the titration vessel. If the reagents continue to run in from the storage
bottle between the dosage process and the siphon off process, please wait a few seconds between the
changes.
We recommend to remove the glass adaptor with the dosing and exhaust hose after adding the
KF-anolyte and to close the ground-in opening with the provided die glass stopper NS 14,5.
64
3.5 Filling the Titration Vessels
Fill the titration vessel approx. up to a half with anolytes that are suitable for the respective application.
(Module 1 and 3). You can even use the pump for modules 2 and 4. If you use a generator electrode with
diaphragm (included in delivery with module 3 and 4), it is necessary to fill an ampoule with catholyte into
the generator electrode. Here, please use also a glass funnel or better a syringe with needle ( Fig. 20).
Fig. 20
3.6 Switch on Device, First Conditioning
Set the stirring speed at the TM 135/TMKF between 3 and 4 (Don’t forget magnetic stirring bar!). Now
switch on the device. The mains switch is situated on the right at the back side of the TitroLine KF Trace.
As soon it is turned on the TitroLine KF trace starts the conditioning process. If the anolyte has freshly
been filled in, the conditioning can take up to 10-20 minutes. The drift display is then > 1500 µg/min. If the
drift has fallen below 10 µg/min, the TitroLine KF trace is ready for first measurements.

4.4 Starting a Titration
Once all preparations have been finished, you can start to titrate samples.
Start the selected method with the <Start>-button in the main menu. At first, the titrator starts the
conditioning process ( Fig. 30). Here the titration cell is titrated until it is dry. This includes the entire
water of the anolyte and even adherent liquids in the titration vessel
*

Now the display asks you to dose the sample. The
liquid sample is now dosed through the septum into the
titration vessel. Advises on how to handle the samples
and some more useful advises can be found in
Chap. 6. The request disappears after a few
seconds.
The input of an alphanumerical sample designation is
only possible with a PC-keyboard connected.
( Fig. 22). Up to 14 alphanumerical characters can
be entered. With the <Backspace> - key it is possible
to delete an entry already made. The input is
confirmed with <Enter> or <F1>. Without an external
keyboard the sample designation is automatically
counted up starting with 1.
With the keyboard TZ 2835 or any other PC-keyboard
the numerical values are entered directly via the
number pad. If no external keyboard is connected, the
numerical values are set with the arrow keys <→>,
<↑>, or <↓>. With the arrow key <→> the respective
number is to be selected. The value is altered with the
arrow keys <↑> and <↓>. The input is confirmed with
<Enter> or <F1>. Please enter the sample quantity in
mg or ml and confirm the input with <Enter> or <F1>.

5.2 Volume and Weighted sample
On delivery the sample/weighted sample is set to “no”. If the result is to be calculated in ppm or %, it is
necessary to enter a sample amount. A weighted sample can be entered manually as mg-value and a
volume as ml-value. If an analytical balance is connected to the titrator, the weighted sample should be
change to ‘Weighted automatic’. Now, you can transfer the weighted sample directly to the titrator via a
keystroke at the balance. ( Fig. 37)

Start Drift
The value of the start drift in µg/min must be equal or even lower in order to start a titration. If the value is
exceeded, the TitroLine KF trace is in the conditioning mode. The standard value is 10,00 µg/min. This
value can be entered from 0,01 to 250 µg/min.
Stop delay time
Is the time in seconds in which the drift-stop criteria are being checked. The stop delay time can be set
between 0 and 60 seconds. The preset standard value is 5 s.
Stop Drift
The stop drift in µg/min is not an absolute end value. The end value of a titration is always the currently
measured drift + stop drift. An example:
If the current drift shows a value of 1,5 µg/min and the stop drift is set to 2,0 µg/min, then the end drift
actually to be reached is 3,5 µg/min.
This means: The lower the entered stop drift, the longer takes the measurement. If a high stop drift (e.g.
20 µg/min) is entered, the measurement ends significantly faster. Low value = exact measurement, high
value = inexact measurement. As stop drift 2 µg/min are preset as standard value. The value can be
entered from 0,01 to 25 µg/min.
Diagram 1 shows on the left the titration curve with the measured variable water per time and the derived
variable drift per time.

Stop Drift Tolerance
If the drift change is within the stop drift tolerance during the entire follow-up time, the measurement will
be ended.
As stop drift tolerance 0,01 µg/min is preset as standard value. The value can be entered from 0,01 to
25,00 µg/min.
In case the drift stop has not been reached as criterion, as new stop criterion is the stop drift tolerance will
be used. It is the derivative of the drift with respect to time. Diagram 2 shows the typical progression of the
stop drift tolerance. Thus, the automatic stop of titrations with side reactions is possible.
Diagram 2: The criterion stop drift as difference to the start drift, the stop drift tolerance as stability
criterion for the drift.
Only one of the two end criteria stop drift and stop drift tolerance must be met to end the measurement.
77
Min. Titration Time
After the minimum titration time has passed, the adjusted stop criteria are checked. The min. titration time
can be adjusted from 0,1 to 30,0 minutes. The standard value is preset to 0,5 minutes for all methods.
Particularly when worked with a baking oven the minimum titration time must be higher.
Max. Titration Time
The maximum titration time is used with samples that generate an increased drift in the end and when it is
not possible to achieve stable end values. The max. titration time can be adjusted from 0,0 to 60,0 min.
The standard value is preset to 10,0 min. for all methods.

Basics and Working Information
7.1 Theory
In coulometry, the KF solution contains iodide. This iodide will be oxidised to iodine at the anode of the
generator cell. At the cathode, in parallel thereto, mainly hydrogen will be generated which will mount in
the form of small bubbles to the surface and hence become withdrawn from the balance. The iodine being
generated reacts immediately with the water according to the Karl Fischer reaction. During the entire
titration process, only iodide is present in the solution. This will change all at a sudden as soon as no more
water is left in the titration cell. As a result of the further addition of iodine, iodine and iodide will be coexisting in parallel and form a reversible redox pair
A voltage is applied to the indicator electrode, and this will cause the iodide to release its electron at the
positive anode, and iodine will form. At the cathode, the electron will again be passed on to the iodine, and
again iodide will form. In this way, it is possible to measure a current which will detect the end of the
reaction. However, this occurs only directly at the surface of the two platinum pins which means that no
iodine can react with the water of the sample. In volumetric titration, the iodine is dosed using a motor
piston burette, but the detection of the end of titration is identical ( Fig. 77)
Fig. 77
84
7.2 Work flow
Immediately after power-up, the coulometer will start to condition the reagent in the titration cell.
Therefore, the anolyte has to be filled in the titration vessel always prior to power-up. In the generator
electrode, hydrogen will be formed at the cathode, whereas iodine will form at the bottom of the anode
of the generator electrode ( Fig. 78)
Fig. 78
The minimum filling height inside the titration vessel should be 3 cm so that the generator electrode is
properly immersed ( Fig. 79): The maximum filling height is 1 cm below the vessel’s top. The
stirring speed should be adapted manually to the filling height. However, the minimum setting of the
speed should not be less than stage 3-3.5.
Fig. 79.
Within a short time, as a function of the amount of humidity contained in the titration vessel, the drift
will reach a stable value. Under normal conditions, this value will be between 0.5 µg/min and 10
µg/min. A drift below 0.5 µg/min is indicative of a previous overreaction (e.g. caused by too slow
stirring), whereas a too high drift indicates an intrusion of humidity or side reactions of a preceding
sample. If an increased drift is stable over a couple of minutes, titration is nevertheless possible since
a delta criterion, defined as a function of the initial drift, is input as a break criterion (please refer to
titration parameters).

7.3 Handling
The indicator electrode is placed in the titration vessel in the opening with the NS 7.5 and connected
to the device using the two blue plugs. Use a funnel to fill in the reagent up to a minimum filling height
of 3 cm. Subsequently, insert the generator electrode. Place a drying tube with a fresh dried molecule
sieve (0.3 nm) on top of the generator electrode. Prior to that, the molecule sieve is to be dried at a
minimum temperature of 250°C for six hours. Use the enclosed cable to connect the generator
electrode to the titrator, with the green plug connecting to the green socket and the black plug to the
black one. Use a fresh septum to close the sample filling hole. The septum has to be impermeable to
atmospheric humidity
If you are using a generator electrode with a diaphragm, a funnel or a needle with syringe should be
used immediately after the insertion of the generator electrode to fill the cathode reagent in the
generator electrode up to the filling height of the anolyte. Apart from that, the working procedure is the
same.
Handling the sample using a one-way syringe
Usually, samples are drawn up using a one-way syringe or a calibrated glass syringe and then
injected into the titration vessel. In this context, the absolute water quantity per sample should be
within the range of 20 µg to 2000 µg of water. If the water quantity is less than that, "accuracy" will
decrees, if it is larger, the duration of the titration will increase. A water quantity of 2000 µg will be
titrated in less than two minutes. The following weighed-in quantities are recommended with the
corresponding quantities of water in the sample:

If a sample is drawn up using a syringe, it has to be ensured that no air will be drawn through the
sample. Depending of the atmospheric humidity, air may contain a lot of water, possibly even more
than the sample itself. It is possible to rinse the syringe beforehand with the sample. The diameter of
the needle is to be adapted to the viscosity of the sample. With low viscous samples, one should use
a 0.8 or even a 1.0 mm needle. The larger the diameter of the needle, the more often needs the
septum to be replaced. The low drift is a good indicator for a tight septum. Under normal conditions
(small needle diameter), it is possible to titrate approximately 20-30 or even more samples using one
septum.
Place the syringe with a sample on the analytical balance, then tare the balance. The sample is dosed
into the titration vessel, the syringe is put back on the analytical balance and weighed back. The
weighed-in quantity, now with a negative sign, is input as absolute value in the titrator or automatically
transferred, respectively.
If a multiple determination is being carried out, it has proven in practice to draw the entire sample
quantity into the syringe and then inject partial quantities of it into the titration vessel. As a rule, this will
lead to smaller standard deviations compared to drawing up each small partial quantity anew. The
main reason for this is found in the risk of taking up atmospheric humidity from the air.
Generally, it is also possible to use a calibrated syringe (e.g. from Hamilton) to add samples as a
volume. As a matter of course, if the result is to be calculated in terms of ppm or %, the density of the
liquid has to be taken into account. It may be input in the calculation formula.
7.4 Working techniques
A distinction is made between the following working techniques:
o Direct addition of a sample using a syringe.
o External extraction
o Working with an oven
Solid samples are usually not placed in the titration vessel, since this would involve a high frequency
of the change of the reagent.
Direct addition of a liquid sample using a syringe
A standard is supposed to be used as an
example to illustrate the working method.
Open the ampoule by breaking off its tip (point
away from user …). Subsequently, place the
open ampoule back in the pack with the
opening pointing up. Now, use a 5 ml one-way
syringe and a 80 mm long needle with a
diameter of 0.8 mm to draw up approximately
5 ml of standard. Prior to that, one should rinse
the syringe one or two times using 1 ml of
standard in order to dry it (
Fig. 81).
Fig. 81
87
Place the filled syringe on the balance as
illustrated, then tare the balance ( Fig. 82).
On the Titroline KF trace, the method is started
by pressing the Start key.
Fig. 82
Subsequently, a part of the syringe contents, for
instance approx 1 ml, is injected into the titration
vessel ( Fig. 83).
The syringe containing the residual quantity of
standard solution is weighed back, the quantity
reading is input as weighed-in quantity on the
coulometer ( Fig. 84).

External extraction is used in the following cases:
o If the water is extracted from the sample only slowly
o If one has to reckon with side reactions.
o Frequently in the case of solid samples
o If a special solvent has to be used
The description of external extraction can be found in an additional document. If required, please feel
free to contact us.
7.5 Verification
The verification of the coulometer is done using a standard. We recommend the use of liquid
standards with percentages of 0.1 mg of water per gram up to 1 mg of water per gram
Recovery is determined by a multiple determination of a standard. The mean value and the relative
standard deviation are determined. Triple up to tenfold determinations are usual. The mean value
reflects the recovered value of the standard. The relative standard deviation indicates the reliability of
the determination. Typical values of a standard with 1 mg of water / g of standard with a weighed-in
quantity of 0.5000 g up to 2.0000 g are given below:
Recovery: 950 - 1050 ppm (97% - 103%)
Reproducibility: +/- 30 ppm (SD); +/- 3 % (RSD)
Linearity can be performed in the same working step if weighing-in was made using different
quantities. Using the 1 mg of water / g standard, the weighing-in operations can start at 0.5 g to be
increased, for instance, up to 2.0 g in six steps. The correlation coefficient and the zero passage may
be used as check parameters. The example below shows weighing-ins of approximately 500 to 1500
mg of water standard. Recovery and relative standard deviation are within the range of acceptance.

7.6 Tips and Tricks
It takes a long time until the drift displays small values (< 8µl/min)
The TitroLine KF trace is switched on, the drift shows value below 100 µl/min. Switch the stirrer off.
After approx 5 seconds, iodine will be generated at the anode. Considering that no stirring action is
present, there is no feedback from the indicator electrode ordering to stop iodine production. After a
few seconds, start the stirrer; you may also shake the titration vessel if required. After the distribution
and reaction of the iodine with the residual water, the drift ought to have dropped down to 0 µl/min.
Please note: as a matter of course, this drift is not “real”, which means one has to wait a little until the
real drift between 0.5 and 5 µg/min will be displayed.
Speed up the drying process of the titration vessel.
In order to speed up the drying process, use a one-way syringe to add so many drops of KF single
component reagent 5 mg/millimetre until a slightly yellowish colour becomes visible. The drift will drop
to a typical value below 100 µl/min. If a drift of 0 µl/min is being displayed, overtitration has occurred.
By adding some drops of methanol or ethanol, it is now possible to add a small quantity of water
again.

Data Communication via RS-232-and USB Interfaces
8.1 General Information
The titrator TitroLine KF trace has two serial RS-232-C- interfaces to communicate data with other
devices. By means of these two interfaces it is possible to operate several devices on one computer (PC)
– interface.
In addition to that, the TitroLine KF trace also has a USB-interface, which can only be used to connect a
PC.
RS-232-C- 1 establishes the connection to a connected computer, a printer with a serial interface or to the
previous device of the “Daisy Chain”. At the RS-232-C- 2 it is even possible to connect additional devices
(Daisy Chain Concept).

8.2 Chaining of Several Titrators TitroLine KF trace — Daisy Chain Concept —
In order to activate several devices in a chain individually, each device must have an own device address.
For this it is at first necessary to establish a connection from the computer to the RS-232-C- interface 1 of
the first devise in the chain by means of a RS-232-C- data cable, e.g. Type No. TZ 3098. With the
additional RS-232-C- data cable, Type No. TZ 3094, the RS-232-C- interface 2 of the first device is
connected with the RS-232-C-interface 1 of the second device. At interface 2 of the second device it is
possible to connect an additional device.
The address always consists of two characters: e.g. address 1 of the two ASCII- characters <0> and <1>.
The addresses can be set from 00 to 15, i.e. 16 possibilities. It must be ensured that the devices in a
chain have different addresses. If a device is addressed with its address, this device will process this
command without sending it to another device. The reply to the computer has also an own address. The
addresses are allocated as described in
Chapter 6.4.
The titrator TitroLine KF trace receives from a computer the commands (if provided with the titrator’s
address) at interface 1 and then sends its reply via the same interface. If the address of the incoming
command does not correspond to the titrator’s device address, the entire command will we redirected to
interface 2. This interface 2 is connected to interface 1 of an additional device. This device checks now
the address and responds to this command like the first titrator TitroLine KF trace. All information (data
strings) which arrive at interface 2 of the titrator TitroLine KF trace will immediately be send to the
computer via interface 1. Thus, the computer receives the data of all devices. In practice it is possible to
connect up to 16 devices to one computer- (PC-) interface.
8.3 Instruction Set for RS-Communication
The commands consist of three parts: Address
two-digit aa, e.g.: 01
Command
e.g.: BP
Variable, if necessary
e.g.: 14
and end of command
<CR> <LF>
Every command must be completed with the ASCII - sign <CR> and <LF> (Carriage Return and Line
Feed). Only if the respective action has ended the answers will be returned to the computer.
Example: The command to dose 12,5 ml, with the previous filling of the cylinder and zero points of the
display, shall be sent to a flask burette with the address 5.
The command consists of the characters: 05DO12.5<CR LF>
In detail:
05
= Device address
DO
= Dosage command with filling and zero points of the display
12.5
= Volume in ml to be dosed
<CR LF> = Control character as command end

Connection of Analytical Balances and Printer
9.1 Connection of Analytical Balances
As it often happens that the sample is weighed in on an analytical balance, it makes sense to connect this
balance to the titrator TitroLine KF trace. To connect the balance to the titrator TitroLine KF trace, the
balance must have a RS-232-C-interface and the connection cable must be configured accordingly. For
the following types of balances there are already assembled connection cables:
Balance
Sartorius (all types), partially Kern
Mettler AT, PR, PM
Mettler, AB-S, AG, PG
Precisa XT-Series
Kern with 9-pole RS232
TZ-Number
TZ 3092
TZ 3093
TZ 3099
TZ 3183
TZ 3180
For all other types of balances it is possible to obtain an already assembled connection cable (on
demand). For this we need detailed information about the RS-232-C-interface of the balance used.
The connection cable is to be connected to the RS-232-C-interface 2 of the titrator TitroLine KF trace. This
side of the connection cables always consists of a 4-pole mini-plug. The other side of the cable can,
depending on the type of balance, be a 25-pole plug (Sartorius), a 9-pole plug (Mettler AB-S) or a 15-pole
specialised plug (Mettler AT) etc.
In order to allow the balance data to be sent to the titrator, the data transmission parameters of the titrator
and the balance must correspond to each other. Additionally, it is necessary to carry out some more
standard settings on the side of the balances:
The balance is to send the balance data via RS-232-C only by means of a print command.
The balance is to send the balance data only after the display standstill.
The balance should never be set to ‘automatic sending’ and/or ‘send continuously’.
‘Handshake’ on the balance must be set to ‘off’, or even ‘Software Handshake’ or ‘Pause’.
No special characters such as S or St are allowed to be used as prefix in the balance data of the
balance data string. In such a case it might be possible that the TitroLine KF trace cannot process the
balance data correctly.
After you have connected the balance with the appropriate cable to the titrator TitroLine KF trace and
have adjusted all settings in the balance software, and possibly in the titrator TitroLine KF trace, you can
now test the data transfer of the balance very easily. Start the one method. Confirm the sample
designation. Then, the display asks you:
a) To press the print-button at the balance
Parameters to ‘weighted sample automatically’
b) To enter the weighted sample
then the parameters are still set to ‘weighted sample manually’
Put an object onto the balance and press the print button. After the standstill of the balance display there
will be beep at the titrator TitroLine KF trace and the transmitted balance data appear:
a) After approx. 5 sec. in the display and the display changes automatically into the measuring display.
b) The weighted sample must again be confirmed with <Enter> or <F1>.
9.2 Connection of Printers
It is possible to connect a printer with a RS-232-C-interface, such as the Epson LQ 300, to the serial
interface 1 of the titrator TitroLine KF trace. Here we need a data cable TZ 3095 (25-pole interface). To
send the results and additional data to the printer, the data transmission parameters of the titrator and the
printer must correspond to each other. The transmission parameters of the printer TZ 3461/TZ 3466 by
SCHOTT Instruments are already correctly configured and the data cable TZ 3090 is included in delivery
of the printer.

11 Maintenance and Servicing of the Titrators TitroLine KF trace
To maintain the functional capability of the titrator TitroLine KF trace it is necessary to carry out all
testing and maintenance works.
Wear Notes
Generator electrode
When the generating electrode is heavily soiled a cleaning with HNO3 (65 %) is recommended. Rinse the
electrode with dest. water and alcohol afterwards and let it dry in a cabinet dryer at 80 °C.
Interruptions of use
If the TitroLine KF Titrator is not used for more than one week it is recommended to remove the
liquids from the titration vessel and if necessary from the generating electrode. Rinse the titarion
vessel and electrodes with dest. water and alcohol afterwards and let it dry in a cabinet dryer at 80
°C.
When the titration vessel is heavily soiled it can be cleaned with a standard laboratory detergent.
Rinse the titarion vessel and electrodes with dest. water and alcohol afterwards and let it dry in a
cabinet dryer at 80 °C.
Cleaning
The titrator TitroLine KF trace is to be cleaned with a wet cloth and common household cleaning
agents.
Both under and back side must be treated dry. The liquid must not enter the housing of the titrator
TitroLine KF trace.
12 Storage, Transport and Environmental Concerns
If the titrator TitroLine KF trace is to be put into interim storage or must be transported, the best way to
protect the device is to use the original packing. However, in many cases this packing is not at one’s
fingertips, so it is recommended to use an equivalent packing.
Previously it must be ensured that the KF-reagent has been removed from the titration
