A method comprising
- purging a sorbent tube with a purging gas;
- detecting a humidity level of fluid exiting the purged sorbent tube with a humidity sensor fluidically coupled to the sorbent tube;
- and
- discontinuing purging of the sorbent tube when the humidity level drops below a selected humidity level.
The method of clam 61, further comprising continuously monitoring the detected humidity levels in the exiting fluid.
A method of purging water from a sorbent tube, the method comprising:
- introducing a purging gas into a sorbent tube;
- detecting a water level in fluid exiting the sorbent tube with a humidity sensor fluidically coupled to the sorbent tube;
- and
- stopping introduction of the purging gas into the sorbent tube as soon as the detected water level in the exiting fluid is below a selected level.
