Install a TGA 4000 . 41
Connect the Purge Gas and System Purge Gas Lines to
the TGA 4000
Perform the following procedure to connect your sample purge gas and system purge gas
lines to the TGA 4000 analyzer regardless of the other components in the purge gas line.
Assuming all the other components of the purge gas line are installed, you will now connect
1/8-in. Teflon tubing to the TGA 4000 using a female connector.
The TGA 4000 System Purge Gas for Balance (1 pc) and Sample Purge Gas (2 pcs)
connectors are mounted to the back of the analyzer.
1. Place the 1/8-in. Teflon tubing from your dry purge gas line onto the inlet labelled
System Purge Gas ALWAYS REQUIRED.
2. Place the 1/8-in. Teflon tubing from your Sample Purge Gas line onto the inlet sample
purge A. If a second sample purge line is desired, connect it to sample purge B (1/8-in.
Teflon tubing).
Connecting purge and system gas lines to the TGA 4000:
NOTE: The dry box purge inlet is only used when an autosampler is installed on the
instrument.
Connect the Cooling Device to the TGA 4000
The TGA 4000 has an integrated cooling system. The cooling inlet and outlet are located at
the rear of the analyzer and are marked Cooling Liquid In and Cooling Liquid Out. The
TGA 4000 is not used in subambient conditions; its temperature range is 15 °C–995 °C.
Therefore, the only cooling devices available for the TGA 4000 are the Polyscience Chiller
(P/N N537-0220/N537-0221, 120 V and 220 V, respectively) and circulating tap water. The
coolant or tap water flows through the cooling jacket that is wrapped around the furnace. It
is important that no condensation forms on the cooling jacket.
NOTE: When operating the analyzer with a cooling device you MUST use a purge gas.
