Maintenance 2
To check for leaks
To check for leaks
When required When the sensor indicates a leak has occurred.
Tools required • Cloths, clean, lint-free (p/n 05980-60051)
• Cotton swabs (p/n 5080-5400)
• Screwdriver, TORX, T-10 (p/n 8710-1623)
Parts required None
1 Remove the front cover and top cover from the instrument.
2 Remove the calibrant bottles.
3 Turn off the Spray Chamber nebulizer pressure, drying gas temp, and
vaporizer temp (for APCI or multimode).
4 Disconnect the nebulizing gas tubing and the LC tubing from the nebulizer.
5 Remove the spray chamber from the instrument.
6 Remove the two screws and remove the cover of the calibrant delivery
system.
7 Check the catch tray. If you see liquid, the pump has a leak. If no liquid is
present, the leak sensor may be out of calibration. See the online Help for
instructions to calibrate the leak sensor.
8 If a leak occurs during a long unattended run, the liquid from the leak may
evaporate to give you the impression that no leak exists and the leak sensor
is out of calibration. Turn the system back on and make sure no leak exists
before you recalibrate the leak sensor.
9 Check the selection valve, the waste fitting, the inlet fitting, and the
calibrant delivery system valves. If you find a leak, correct it and check the
remaining locations.
10 Dry the catch tray and leak sensor.
11 When the catch tray and leak sensor are thoroughly dry, reassemble the
instrument.
The spray chamber operates at very high temperatures. Give the spray chamber time
to cool before proceeding.
