Gas Chromatographs
Application Data Sheet (ADS)

For all non-BTU Applications, the Application Data Sheet
(ADS) is required before the GC Division can quote the
Gas Chromatograph.

The ADS is also an excellent tool during the sales process
to help prompt the customers for information and an aide
to up-sell the GC, and continue to increase our market
share.

ADS – Option Information
Model
500
Model Preference:
If the customer has a preference (e.g. They have an installed base
of a particular model) for a style of GC, this should be entered here.
Note that if the application is not suitable for the selected application,
we will contact them to confirm the style of GC can be changed.
If the customer has no preference, then leave this blank.
Model
700
Some reasons for a particular GC are as follows:
-700: DC power required. Small footprint. Do not want separate
controller. Dual Detector application. FID application.
-500: Installed Base of 500’s. Remote controller required.
-1000A: Difficult application. Instrument air is available. The model
1000A will usually be selected by the application engineering
department of the GC group when the application is more advanced.

Area classification:
Area classification refers to the hazardous area rating required. For
most applications it will be Class 1-Div 2, or Class 1-Div 1.
Agency Certifications refer to the third party hazardous area
certifications required. CSA is the Canadian Standards Association
(accepted in the US when certification is required) and ATEX is the
European certification. If the end destination is in Europe, Asia or the
Middle East, ATEX certification is usually required.

Available Utilities:
For more complex applications, some external utilities may be
required.
-Instrument Air. When external “Block and Bleed” solenoids are
required, or the Model 1000A is being offered, clean dry instrument
air with at least 110 PSIG is required.
-Steam, Water or Nitrogen. For very specialized applications only.

GC Mounting:
The model 500 can be only mounted with a floor mount. The Model
700 can also be supplied with a wall mount and a pipe mount. The
Model 1000A can be supplied as either a floor or wall mount.
The pipe mount is for a 2, 3 or 4 inch pipe mount.
Most applications will use the floor mount.

Controller:
Integral – The Model 700 and Model 1000A use an integral
controller. The model 500 has an optional “explosion proof housing”
for the 2350A controller.
19” Rack-Mount – The standard offering for the Model 500 GC is a
remote mounted “safe area” 2350A controller.
Keypad/Display – The 2350A controllers (remote or integral) has
the option of a large keypad and 8 line/41 character display. The
Model 1000A and the model 700 have the option of the full color
LCD display with touch key operation.

Power:
The model 500 is available for 120 VAC or 240 VAC power supplies
only.
The model 700 and 1000A can use 120 VAC, 240 VAC or 24 VDC.
Note that the DC unit has a minimum supply voltage of 24.5 VDC, so
voltage drop across a long power cable run, or poor power supplies,
can cause operational issues.
For destinations outside of the US, the power supply voltage needs
to be confirmed as often 220/240 VAC is required.

# of Serial Ports and Config:
This is a critical question which can help eliminate the competition! We have up to 8 serial ports available on
the Model 500, and 6 serial ports for the Model 700/1000A.
Standard option is 4 for the 500, and three for the Model 700/1000A.
RS 232 is a 3 wire used for short distance point to point communication for local access and locally mounted
flow computers and RTU’s and control systems.
RS 422 is a 4-wire long distance point to point communication which can be multi-dropped.
RS 485 is a 2-wire long distance multi-point communication which is commonly used to RTU’s and flow
computers and DCS systems.
Increasing the required serial ports to 3 or more will remove the opposition GC’s from consideration. An
example application is communication to a flow computer, local operator access, and third-party access.
Gas Chromatographs
ADS – Option Information
Data Communication:
Communication to the DCS, SCADA system, RTU or Flow Computer.
-Analog. 4-20mA outputs. Can be used for component values, calculated values, BTU
output, or even Specific Gravity and Density.
-Modbus. The most common serial communication method.
-OPC. For use with some SCADA and DCS systems, not commonly used. For the Emerson
GC we use Modbus over Ethernet to talk to an OPC Server.
-Ethernet. Modbus TCP/IP communication over a Ethernet connection. Ethernet allows for
Modbus communications and diagnostic access over the same link at the same time.
Gas Chromatographs
ADS – Option Information
Analyzer Maintenance Network:
This is the connection for remote access for diagnostic purposes.
-Ethernet. This is an option which is highly recommended due to the
speed and ease of connection.
-RS-485. Two wire long distance communication, will require a RS232 to 485 converter to allow access via a computer.

ADS – Option Information
Serial Protocol:
-SIM2251. This is the standard Daniel Modbus protocol which
simulates the Modbus interface of the 2251 controller. Sometimes
also called ENRON Modbus. Most flow computers or RTU’s use this
protocol and require little configuration.
-Gould Modbus. This is the Modbus protocol commonly used by
PLC’s and DCS systems. Note that this needs the Modbus map to
be custom configured.

Analog and Digital I/O:
The I/O capabilities of the Daniel GC is a major advantage over opposition GC’s.
Analog Inputs – Available on the single detector model 500 and the model 700/1000A.
Can be used for other analyzers (e.g. Moisture or H2S) or for pressure transmitters for the
Carrier gas and Calibration gas.
Digital Inputs/Outputs – Can be used for pressure switches, or for switching to “alternative
stream sequences” mode. The alternative stream sequence mode is a useful tool which allows
for a GC to have two stream sequences. For example, the normal mode could be just analyzing
stream 1, and the alternative stream sequence can be stream 1, stream 2, stream 1 etc.
Very useful for redundant systems and for measuring two streams where only one is active at a

time.
ADS – Option Information
Digital Outputs: Can be connected (via a relay) to solenoids, valves or alarm contacts on
supervisor systems for alarm activation. One user used the mA input for a H2S signal, and
connected the digital out to the slam-shut valve to provide a high H2S shutdown on the
pipeline inlet.
Analog Outputs: Std is 4 non-isolated outputs, options are 4 non-isolated/4 isolated
outputs (8 total) or 12 non-isolated outputs. Often used for calculation outputs or
component composition values to non-serial communicating devices.

Auto-calibration Preference:
For gas applications, the GC can be set to auto-calibrate. This is
standard for custody transfer or environmental applications.
For liquid applications, auto-calibration is typically not used as
setting the liquid calibration standard for analysis is a manual
procedure.
Gas Chromatographs
ADS – Option Information
Sample System Required:
Generally the GC will be supplied with a sample handling system
(SHS) mounted under the Analyzer Oven.
-None. The customer will supply the sample handling system and
will ensure a dry-gas sample will be supplied to the GC.
-Attached. The standard offering with the SHS mounted below or
beside the GC.
-Remote. The sample system is built separately to the GC and is
mounted remotely from the GC.
Gas Chromatographs
ADS – Option Information
Auxiliary Options:
-Carrier Gas. Includes Carrier gas bottles, pressure regulators and
manual switchover manifold.
-Cal. Gas. Includes appropriate calibration gas(es), and pressure
regulators.
-Probes. Sample probe(s). Probes will be selected to be appropriate
for the application as described on the Stream Composition Sheet
(sheet 2).
-Tropicalization. For salt laden or very corrosive environments the
GC and Electronics boards can be coated with a clear coat epoxy.

Factory/Field Support:
FAT – Factory Acceptance Test. The delivery of the GC will be held up until a
representative of the end-user comes to the factory (in Houston) and carries out a
checkout test with the lab technicians.
Start-up – A factory trained technician will come to site to start the unit up for the first time.
Training – Training can be provided in Houston (regularly scheduled throughout the year)
or onsite as a part of the start-up visit.

Special Instructions or Notes:
Any special instructions such as shelter requirements, analysis time
limits or any other information that will be important to obtaining an
accurate quote.
If there is customer specification documents to refer to, they should

ADS – Stream Data Sheet
Stream Data Sheet
This page is where the individual stream data should be entered. Calibration Gas
Stream information does not need to be entered here, as this will be considered
automatically by the application engineering team. Note that there are 4 streams
available. If more streams are required, just copy this page and include it in the
submission.
The Model 500 can have up to 12 streams (including calibration gas) and the
model 700 can have up to 8 streams (7 samples and one cal). More streams can
be accommodated with discussion with the factory.
Gas and liquid applications can be done on the same GC, however, application
Gas Chromatographs
engineering will decide if it is appropriate to mix two applications on the one GC.

Customer information:
This should be the same as the first page.

Stream Parameters:
Stream Tag #
Stream name – for example “De-Butanizer Bottoms”
Process Control or Monitor – Will the stream composition be
used as a part of the process control scheme, or is it for
monitoring only. This is used for process applications to decide
the tradeoff between component separation and analysis time.
Pressure at Sample Point – Required information to ensure
that the sample will be taken in a single phase (gas/liquid).
Temperature at Sample Point – Required information if a
sample probe is being offered. This is used in conjunction with
the pressure and nominal composition to determine that the
sample is single phase (gas or liquid) and therefore can be
sampled accurately.
Gas Chromatographs
ADS – Stream Data Sheet
Stream Parameters [continued]:
Phase at Sample Point – used in the determination of the
sample probe to be used, and the sample handling system to
design.
Tap Distance to Analyzer – Used to determine the location of
the Sample Handling System and to size the sample lines.
Return Sample to Process? – Generally the vents from the
GC will go to atmosphere. The system can be designed (if
required) to return the unused sample back into the process,
usually for environmental reasons.
Return Pressure – If the sample is to be returned to the
process, the return point pressure is required to calculate the
flow rates through the system, or to determine if a sample
pump is required.
Gas Chromatographs
Contaminants – Any hazardous (to components or humans)
or significant contaminants need to be identified.
ADS – Stream Data Sheet
Stream Components:
The name of the stream components and the units should be entered
into these columns.
Note that all the components of the stream should be entered, not only
the components to be measured. If there is a significant component that
is not to be measured, it is important to list it so that the application
engineers can ensure that it will not affect the measured components.
For example, if there is significant levels of H2S (>10ppm), but only the
hydrocarbons are to be reported (they may have a separate H2S
analyzer), the H2S value must be included in the component list.
Gas Chromatographs
ADS – Stream Data Sheet
Normal:
The concentrations of each component normally expected to
be seen in the stream should be entered in this column. Note
that this does include the components not to be measured, but
are to be found in significant quantities in the sample stream.
Gas Chromatographs
ADS – Stream Data Sheet
Measured Range:
The minimum and maximum measured concentrations
should be entered in these columns. Note that this is only for
the components to be measured and reported, not the
components which are in the stream, but are not to be
measured.

ADS – Stream Data Sheet
Stream 2, 3 and 4:
For multiple stream applications,
the information for the other
streams are entered here. If
more than 4 sample streams are
required then a second stream
data sheet should be completed

Using the Application Data Sheet
Correctly completing the ADS allows you to:
– Discuss the application in detail with the customer to
provide the best solution
– Answer all the questions the GC division may have,
before they ask them
– Greatly improve the time to quote
– Ensure the customer gets what they want
