1 Installing TD-100

1.1 Unpacking TD-100

Remove the instrument from its packaging. It is strongly recommended that the instrument packaging

is retained for future use if ever the system is to be shipped using conventional carriers. Shipping the

instrument in non-standard packaging may irreversibly damage the equipment and invalidate the

warranty. It is recommended that 2 people unpack the instrument to minimise the lifting hazard.

Check the packing list included with the instrument to confirm the entire ship kit is present

Before installing the TD-100 determine whether there are any accessories to be installed (such as MFCs

or internal standard accessory). Any accessories should be installed before installing the TD-100 onto

the GC. See appendix A for accessory installation instructions.

1.2 Installing the transfer line

TD-100 is supplied with a universal transfer line (SERUTDSERUTDSERUTDSERUTD----5003500350035003) to convey desorbed analytes from TD-

100 to a gas chromatograph or other analytical system. The sample path utilises a deactivated fused

silica line (0.25 mm I.D. and 0.35 mm O.D.) heated over its entire length by means of a distributed

heater and at the GC end by heat conduction from the GC oven. The line is 1 m long, which is sufficient

to reach most gas chromatographs even when a mass spectrometer is attached.

NoteNoteNoteNote: The parts supplied can be used in other combinations to suit particular instrument

configurations.

1.2.1 Installing the Transfer Line onto the GC

There are two options for transfer line installation, one requires use of a hole in the top, side or back of

the GC oven, while the other option is to gain access via an unused heated injector port.

Option 1 Option 1 Option 1 Option 1 –––– Through Through Through Through Hole in Oven WallHole in Oven WallHole in Oven WallHole in Oven Wall

1. Locate a hole in the inner oven wall with a corresponding hole leading to the outside of the

instrument.

2. Where necessary, displace the oven insulation material such that the transfer line heater can be

fitted directly against the external face of the oven wall.

Photograph

3. Place one of the washers provided in the TD-100 shipping kit on the external face of the oven

wall, over the hole through which the transfer line will be passed.

NOTENOTENOTENOTE: A number of different washers are provided. The washer required will be determined by the

hole in the oven through which the transfer line will pass.

4. Fit the GC end of the TD-100 transfer line trough the hole in the washer and on through the hole

in the GC oven wall.


5. Place a second washer over the TD-100 transfer line so that it can be secured against the inside

wall of the GC oven.

6. Fit the clamp (SERUTDSERUTDSERUTDSERUTD----1125112511251125) onto the transfer line, followed by the spacer (SERUTDSERUTDSERUTDSERUTD----1232123212321232)

secure with the M6 nut supplied with the transfer.

Option 2Option 2Option 2Option 2 –––– Through Heated Injector PortThrough Heated Injector PortThrough Heated Injector PortThrough Heated Injector Port

NOTENOTENOTENOTE: This option is only suitable if the inlet will not be required at any time.

1. Remove components from the injector (e.g. septum, liner etc.) to enable the transfer line to pass

through unobstructed.

2. As the entry hole will generally be larger than the diameter of the metal line sleeve, one or more

of the large washers supplied will be needed.

3. When in operation the injector body should be heated, and should be set to run at a

temperature equal to the TD-100 flow path temperature setting.

1.2.2 Installing the fused silica transfer line insert

Once the heated line has been fitted to the GC, the fused silica plus associated PTFE sleeving (SERUTD-

5093) (see shipping kit) are pushed from the GC end, along the 1/8-inch aluminium tube until they

protrude from the other (TD-100) end of the transfer line.

Trim the PTFE sleeve to ensure enough fused silica is exposed.

Connect the fused silica transfer line to the GC column with a pressfit (C-QSC10) or alternative

connector.

1.2.3 Connecting the transfer line to TD-100

Place TD-100 on the bench on the most convenient side of your gas chromatograph. Ensure that the

transfer line will reach from the top of TD-100 to the selected entry point into the GC oven.

(NoteNoteNoteNote: if stainless steel tubing is unavailable, green PEEK tubing can be used in its place)

In this alternate configuration there is no need to regulate the carrier gas supply to the EPC module as

close to the TD-100 supply pressure in order to get stable behaviour. This makes it especially suitable

for constant column flow methods where the pressure is ramped during a run to maintain a constant

column flow.


2 Installing the software

Ensure that your PC meets all specifications presented in the site preparation document and is

operating under a 32-bit version of Windows™. It is advised to close down other applications on your PC

while installing the TD-100 software.

1390-1022 Screw 1

However, if these parts are not available at installation both the carrier gas and septum purge lines

running between the EPC module and the Split/Splitless injector must be cut and extended using 1/8”

unions and green PEEK tubing in order to facilitate connection to TD-100.

NoteNoteNoteNote: When installing onto an existing 6890GC the firmware on the GC must be A.03.08 or later (for A-

series) or N.04.09 (for N-series). To check the firmware version, use the keyboard on the GC,

press > Options > Diagnostics > Instrument Status and then scroll down to ‘Version’ where you

will see the version of the firmware running on the instrument.

3.1.1 Procedure

1) Remove the top rear cover on the GC to provide access to the EPC module that is going to be used to

regulate the carrier gas supply to TD-100.

Removing the rear panel to access EPC modules

2a) Remove the 3 port EPC block assembly from the split/splitless EPC module.

Fit the replacement EPC block assembly, and route the 1/16” tubing through the rear panel of the GC

and towards the TD-100.


Location of EPC module with the 2 port EPC block fitted

2b) If a replacement EPC block assembly is not available, the septum purge and carrier gas lines must

be cut, extended, using 1/8” brass unions and 1/16” green PEEK tubing, and routed through the rear

panel of the GC towards TD-100. The lengths of PEEK tubing used should be no longer than required to

reach the TD-100.

Carrier and septum purge lines extended with unions and PEEK tubing

The stainless steel tubing for the carrier supply line is 1/16” while the septum purge line is 2 mm and

will require a different ferrule when connected to the 1/8” brass union.

(NoteNoteNoteNote: two 1/8” brass unions, 3 m of 1/16” green PEEK tubing and 1/8” graphitized vespel ferrules,

including one for 2 mm tubing, are all contained within the Agilent GC Installation Kit.)

3) Connect the carrier gas supply line to the ‘Carrier Inlet’ port of TD-100 and connect the septum

purge line to the ‘Pressure Outlet’ port.

3.1.2 6890 inlet settings

Before the column pressure value is set, the MODE of operation of the inlet has to be configured.

For correct control of TD-100 the mode must be set only to SPLITLESS, and not split.

In addition the splitless purge time value must be set to 999.99 minutes DIRECTLY through the

keyboard of the GC (6890 firmware revision A.03.08 or later required). This value cannot be set using

the Chemstation software as the number is rounded to 1000.0 minutes. Setting this value forces the

split/splitless inlet to remain permanently in the splitless mode.

The purge flow value is irrelevant. Once the split/splitless inlet has been configured as described the

column head pressure can be setup to give the desired flow rate/ velocity down the column.

3) Connect the carrier gas supply line to the ‘Carrier Inlet’ port of TD-100 and connect the septum

purge line to the ‘Pressure Outlet’ port.

3.2.2 7890 Inlet Setup

There are several settings that must be implemented on the 7890 whenever the split/splitless EPC

module is controlling the carrier gas supply to the TD-100 thermal desorber. In the Inlet settings the

mode must be set to ‘Splitless’, the purge time must be set to exactly ‘999.99’ minutes and Gas saver

should be set to ‘Off’. In the Instrument Configuration menu the Auto prep run should be set to ‘Off’.

Having completed this, the system should now be ready to use.

3.2.3 7890 Inlet Settings

If the pressure is not correctly controlled after inputting the above settings then turn ‘Auto prep run’ to

‘On’.

3.3.1 Gas connections between TD-100 and the Shimadzu AFC

1) The Shimadzu GC is fitted with two molecular sieve filters, one in the carrier gas line and one in the

septum purge line. Remove the filter from the carrier gas line and replace with the Shimadzu fitting GM-

1.6L. The filter on the septum purge line should remain in place to prevent back diffusion of air/water.

2) The carrier gas out line from the Shimadzu AFC (“CG Out”) is now connected to the “Carrier Inlet”

port on the back of TD-100 using a 1 m length of green PEEK tubing.

3) The “Pressure Outlet” from the back of TD-100 is now connected - with a similar length of green

PEEK tubing - to the molecular sieve filter on the septum purge line (and hence to the (“SP In”)) on the

Shimadzu AFC. It is important that the two lengths of green PEEK tubing are the same length. Carrier

gas is supplied and regulated upstream of the system in the supply line and it’s pressure is monitored

downstream of the system in the septum purge line.

3.3.2 Configuring the Shimadzu GC software

1) The inlet Split Mode on the Shimadzu GC must be set to Direct.

i. To access the Split Mode press the “FLOW” key on the GC keypad.

NoteNoteNoteNote: In the case of GCs with two or more AFC units it may be necessary to press the “FLOW” key

repeatedly until the correct one is displayed.

ii. Move the flashing cursor over the “Split Mode” (type using the arrow keys on the GC keypad).

iii. Using the right arrow key, select “DIRECT” mode as shown, and press the “ENTER” key on the GC

keypad.

Setting Inlet Mode as Direct on Shimadzu GC

2) The AFC module allows read out of the total flow supplied to system - this is ideal for setting split and

trap / desorb flows and for troubleshooting leaks.

i. To view the total flow supplied press the “FLOW” key on the GC keypad as above.

ii. The Total Flow in ml/min is always displayed (above the Split Mode) as shown above.

3) The septum purge flow should be set to a flow rate of around 5 ml/min

i. To set the septum purge flow display the “FLOW” screen as described above.

ii. Press the button to the right of the “PF3” key (below the screen) as shown below. This displays a

second set of commands for the PF keys.

iii. Select the purge command on “PF3” and enter the desired value. A flow rate of 2-5 ml/min is

recommended.

3.3.3 Flow stability

AFC works with both impeded (traps containing porous polymer e.g. Tenax) and un-impeded (traps only

containing carbon sorbents) traps, with no carrier gas instability generally noted (even with 90-100 psi

supplied to the inlet of the AFC system). However should any instability in the carrier gas occur it may be

necessary to dampen the reaction of the AFC controller.

i. Press the “FUNC” key on the GC keypad.

ii. Enter “7”, enter “5”, enter “1201”, enter “1”. This will display the “Flow Adjust” page.

iii. For instruments with two or more AFC units, press the “PF2” button to select the correct flow unit.

iv. Move the cursor to the “I Time” entry in the “Flow” column.

v. Change the value from “1” to “4” then press the “Enter” key.

3.3.4 Ready / Start connections between TD-100 and Shimadzu GC

The remote cable connections between TD-100 and the GC are shown below. The TD-100 - GC cable

(SERUTD-5095) has a 25-pin D-type connector at the TD-100 end and free wires at the GC end. Four

wires need to be inserted into the connection block at the rear of the QP2010 as shown below.

Ready / Start connections between TD-100 and QP 2010

When connected to the Shimadzu GCMS system the TD-100 ready (in) logic must be set to Open as

shown below. To set the logic select view>options from the drop down menus to open the options

dialogue box.

3.4 TD-100 Electronic Gas Control with the Thermo DPFC

A TD-100 can be integrated into the DPFC system of a Thermo Electron GC. The DPFC module regulates

the carrier gas supply upstream of the TD-100 and its pressure is monitored downstream of the system

in the septum purge line of the DPFC module. The split line of the DPFC module remains unused.

3.4.1 Procedure

1) The carrier gas supply and the septum purge lines that normally run from the DPFC to the

split/splitless injector need to be cut and fitted with 1/8” brass unions (note: the carrier line requires

use of graphitised vespel ferrule with the 2 mm hole – part number Z-0402).

2) Extend these two lines with the length of green PEEK tubing so that they can reach the back panel of

TD-100. The carrier gas line from the DPFC module should be connected to the TD-100 ‘Carrier Inlet’

and the septum purge line should be connected to the ‘Pressure Outlet’.

3.4.2 Configuring the Thermo GC software

Having completed the physical connection between the Thermo Focus or Trace GC and TD-100 the next

step is to configure the inlet settings.

1) The GC must be set up for back pressure regulation. To do this the DPFC must be removed and the

switches set in the correct position for purge & trap. Setting up this configuration is described in the kit

adapter for the purge and trap concentrator system installation guide.

2) The inlet that is being used to control the TD-100 carrier gas supply should then be set to operate in

split mode but the split flow should be set to zero (off).

3) The only other important consideration is to ensure that the pressure of the carrier gas supplied to

the DPFC module is only 10-15 psi greater than the pressure that the DPFC module is required to supply

to TD-100.

4 Installation qualification

4.1 Testing the ECC setup

Once the connections and inlet settings have been correctly set up it is extremely important that the

following test of the ECC carrier gas supply is carried out:

During the desorption of the TD-100 cold trap the total flow and pressure supply of the ECC module

should be monitored. Both pressure and flow readings should be stable.

If there is any variation in the pressure reading of the ECC module, or if the flow fluctuates by more

3mL/min, this indicates that the setup is not optimized. In such circumstances the reproducibility of

analysis is likely to be poor.

ECC instability during trap desorption

Such fluctuations can normally be avoided by regulating the carrier gas supply to the ECC module to 10

psi above the greatest pressure required by the TD-100 in the course of a run, see below. This is almost

always effective in removing any instability when using a constant pressure method, but may not be

effective for constant flow methods.

In situations where the pressure and/or flow are unstable despite the appropriate regulation of the
