ProStar 335 Photodiode Array Detector
89
Maintenance
General
The Varian ProStar 335 detector requires three maintenance
procedures to be performed periodically:
Changing and cleaning the flowcell
Replacing the lamp(s)
Calibrating the lamps
Flowcell removal and replacement will be necessary if a flowcell
of different pathlength is desired, or if cleaning procedures do not
satisfactorily clean the cell.
Lamp replacement is required when the lamp output deteriorates
to the level that it affects the reliability of analytical results.
Lamp calibration is recommended every 2000 deuterium lamp
hours, and whenever a lamp is changed or the flowcell type is
changed.
This chapter also covers fuses and cleaning the instrument.
