1. Turn off the pump flow and then the gas flow:
a) Turn off the pump flow to the detector. Wait at least 5 minutes.
During the waiting period, the detector drains any remaining
mobile phase to waste.
b) Turn off the gas flow on the detector.
c) Wait until the system pressure is down to zero before you
continue.
d) Turn off the gas supply to the detector.
2. If you operate the detector from the chromatography data system,
disconnect the detector from the software.
3. Turn off the detector with the main power switch.
