Preparations
1. Flush the detector with the detector gas flow being turned on. For
recommendations on flushing the detector, see section 7.4.3
Flushing the Detector between Analyses, page 172 .
2. 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.
3. Turn off the detector and
all
other system modules with their main
power switches.
4. Disconnect the power cord from the detector and power source.
5. Disconnect all cables and capillaries to other devices.
6. Disconnect the gas and drain tubes:
a) Disconnect the gas inlet and exhaust tubes from the detector:
On the push-in fittings on the tubes, push in the locking ring of
the fitting with the multitool. Pull the fittings off from the gas
connectors on the detector.
b) Disconnect the leak tubing and the waste tubing from the drain
ports on the right side of the detector.
Follow these steps
1.
If applicable
Remove any modules that stand on top of the detector in the system
stack.
2. Remove the detector from the system stack.
The following steps require a team effort:
a) Take the detector on both sides and lift it slightly.
b) Grasp the detector from below and lift it from the stack.
c) Place the detector on a clean and stable surface.
To restack the detector in the system stack, see section 5.5.1, page 67 .
