The sample purge gas inlets (A and B) are used to purge the furnace, and are part of the
internal gas selector (which has two inlets and one outlet). Argon or nitrogen of 99.9%
minimum purity is recommended for purging the sample area. Other gases such as air or
oxygen may also be used. The flow rate of the sample purge gas is controlled using the
software.
NOTE: The gas must be dry. A flow rate of between 20 and 40 ml/min is recommended.
The procedure for connecting the purge gas supply includes the following steps:
•
Connect the purge gas line to the system gas supply.
• Install a filter dryer (optional).
• Connect the purge gas lines to the STA 6000.
Connect the Purge Gas and System Purge Gas Lines to
the STA 6000
Perform the following procedure to connect your sample purge gas and system purge gas
lines to the STA 6000 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 STA 6000 using a female connector.
The STA 6000 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 required, a second sample purge line (1/8-in. Teflon tubing) can be connected to the
purge B inlet.
Connecting purge and system gas lines to the STA 6000 (Your instrument may
show a slight variation):
NOTE: The dry box purge inlet is only used when an autosampler is installed on the
instrument.
