Using the Gas
Switching Accessory
You can use the Gas Switching Accessory to
turn the purge gas on and off or to switch
between two different purge gases during a TGA
experiment. Before starting and experiment that
uses the Gas Switching Accessory, make sure its
power switch is on, and make sure the necessary
gas sources are properly connected.
The Gas Switching Accessory can be controlled
by the Gas segment in the method (see the online
help and documentation for further information).
Connect the Gas Switching Accessory to the
purge port only, when switching between gases
during an experiment. Attach the inert gas to
GAS 1 and the other gas to GAS 2.
Consult your Gas Switching Accessory
operators manual for further instructions.
