CHAPTER 1 INTRODUCTION
1.1 Product features
Feature 1:
Useful to conduct experiments of chemical reactions between samples and an
active carrier gas (e.g. air). Experiments with varied heating conditions can be
performed using the programmed heating feature of Multi-Shot and Double-Shot
Pyrolyzer.
Feature 2:
Quick and easy switching of carrier gases. Employing magnetic valves, dead
volume of the flow path is minimized (less than 5ml).
Feature 3:
Fail-safe mechanism is employed. When the pyrolyzer is not in use, the mechanism
prevents the active carrier gas from flowing into the separation column.
Feature 4:
Auto switching of flow path with electromagnetic valves through only PC control
display of EGA/PY-3030D or PY-3030S.
1.2 System Overview
Fig. 1.1a-c show the flow diagrams of the CGS-1050Ex connected with Py-GC system in the cases of
each switch position.
Two kinds of different carrier gases (normally He and air) connected to the
device are switched by the magnetic valves 1 and 2.
And the gas selected is introduced into the
pyrolyzer or GC injection port by the magnetic valve 3.
The flow rate of He gas is controlled by the flow controller of GC (FC).
The air flow rate is
controlled by the mass flow controller mounted on this device. See chapters three and four for details
in connections.

CHAPTER 3 INSTALLATION
3.1 Installation Procedure
Follow the steps 1 through 7 to properly install the device. Please refer to Table 3.1, Fig 3.1 of this
manual and Chapter 3 of the Pyrolyzer Operation manual.
Step 1: Set the device in the vicinity of a GC system.
Step 2: Referring to Fig. 1.1 and Fig. 1.3 connect the GC flow controller (He or N2) to the “IN (From
GC)” port on the rear panel using a tubing supplied.
Step 3: Connect the “Out (GC INJ)” port to the tubing from the GC injection port using a tubing
supplied.
Step 4: Connect the Pyrolyzer “Carrier IN” tubing to the “OUT (PY)” port.
enough to connect them, use a 1/16・tubing supplied.
If the tubing is not long
To connect this tubing to “Pyrolyzer
Carrier IN” tubing, use a 1/8” union and rubber seals (contained in the Pyrolyzer installation
kit).
Step 5: Connect an active gas, e.g.. Air, to the “IN (Air)” port.
The customer must prepare the
tubing for this purpose.
Step 6. Connect the valve control cable (to connect with EGA/PY-3030D or PY-3030S only) between
valve control connector and the “CGS VALVE” connector of the temperature controller of
pyrolyzer.
Step 7: Plug the power cable supplied to the power socket.
!
CAUTION
When using Air as an active gas, GC grade air from a cylinder should be
used and set the pressure to 300kPa. Using compressed air (e.g. air
from a compressor) may result in contaminations (moisture and/or old)
of the flow path.

3.2 Testing Gas Leakages and Checking Tubing Connections
3.2.1 Testing Gas Leakages
When tubing connections are completed, test the whole system to make sure there is no gas leakage
using a gas leak detector or leak check liquid.
3.2.2 Checking Tubing Connections
If gases are connected to wrong ports, serious damage of the separation column may result. To avoid
misconnections of tubings, check connections of tubings according to the procedures described
below.
Step 1: Remove the pyrolyzer furnace from the GC injection port.
Step 2: Remove the separation column from the GC and plug the outlet of injection port with
something like a cap nut.
Step 3: Set the switches of the device “He”, “GC” and “MANUAL” as shown in Fig.3.2 (He selected as
carrier gas, and supplied to GC injection port)
Step 4: Set the column inlet pressure to 100kPa, total flow rate to 100mL/min by the GC flow
controller.
Then check the column pressure to see if it reaches the set point.
Wear a pair of safety goggles

CHAPTER 4 OPERATION
4.1 Manual operation
STEP 1:
Turning the power switch to ON.
Plug the power cable to the device, then turn the power switch to ON.
Power indication lamp on the
front panel will come on.
STEP 2:
Set the control mode switch (Fig. 1.2) to “MANUAL”.
STEP 3:
Selecting carrier gas.
Select either He or Air (or any other active gas) by the Air/He selection switch. The selected gas is
indicated by the lamp on the front panel.
STEP 4:
Setting carrier gas flow direction.
Set carrier gas flow direction to either Pyrolyzer or GC Injection port by the PY/GC selection switch.
When the Pyrolyzer is used, flip it to “PY” and flip it to “GC” while the Pyrolyzer is not used,
STEP 5:
Adjusting carrier gas flow rate.
Each carrier gas flow rate can be adjusted by the flow controller shown below.

4.3 Remote control
Verify that the valve control cable is connected between “VALVE CONTROL” connector on the back
panel of the CGS-1050Ex and the “CGS VALVE” connector of the temperature controller of EGA/PY3030D or PY-3030S.
Set the control mode switch to “AUTO”. When “AUTO” mode is selected, “PY” is automatically
selected and “GC”/”PY”, “He”/”AIR” switches become nonfunctional.
“He”/”AIR” selection can only be done through EGA/PY-3030D or PY-3030S temperature control
software. Refer to the Chapter 4 of the operation manual of your pyrolyzer for detail about controlling
CGS-1050Ex from EGA/PY-3030D or PY-3030S.

CHAPTER 5 USING AIR AS CARRIER GAS
An example of PY-GC analysis using Air as carrier gas is described below.
1) Plain glass liner (no packing) is recommended for the GC injection port.
!
CAUTION
We strongly recommend that you use this device in combination
with Selective Sampler (SS-1010E) when conducting Py-GC
analysis using air as a carrier gas to prevent the separation
column from accidental damage.
2) Cool the column oven down to room temperature. Then load up a sample to the double-shot
sampler or single-shot sampler and install it on your pyrolyzer.
3) Select Air and PY.
4) Immerse the front of a separation column into liquid nitrogen in a Dewar as shown in Fig. 5.1.

Ver. 1.10
5) Drop the sample cup.
Gases formed from the sample will be trapped at the front of the column
dipped in liquid nitrogen.
6) Switch the carrier gas to He after 30 seconds since the pyrolysis has started.
7) If Selective Sampler (SS-1010E) is used, switch the sampling “OFF”.
8) Wait for at least 10 min to purge the air with He.
8) Remove liquid nitrogen, close the GC oven door then start the oven temperature program to
analyze the gases.
!
CAUTION
If MS (Mass Spectrometer) is in used as a detector, wait enough
time to purge air from the MS chamber after switching the carrier
gas to He. For example, 30m-long, 0.25mm id column is used, wait
at least 5 min after the carrier gas is switched to He. Waiting time
depends on column flow rate of carrier gas and the pumping
efficiency of MS.
