Introduction to the Agilent 7100 Capillary Electrophoresis System

Maintenance 8
Changing the Lamp
Inserting a New Lamp
1 Hold the new lamp by the metal ring to avoid touching the glass surface.
Fingerprints absorb light and can reduce light intensity.
2 Insert the lamp into the lamp compartment. Position the lamp so that the
notch in the lamp ring matches with the pin on the detector housing.
3 Tighten the two lamp screws.
4 Connect the lamp cable connector and fix the cables into the channel in the
foam.
5 Close the detector lid without clamping the lamp cable.
6 Close the top cover. Turn line power on.
7 Boot the Agilent ChemStation and turn the lamp on.
8 Allow the lamp to warm up for about 1 hour.
9 Perform an Intensity Test in the Detector Test suite in the Lab
Advisor/Instrument Utilities software to determine the initial lamp
intensity of your new lamp. Store the result for you own reference.
Further Action
If the instrument fails this test, check the following:
• correct seating and connection of the lamp cables,
• correct seating of the cassette, and
• if the green alignment interface without capillary is used, check for
contamination of the interface.
If none of these reasons apply, call Agilent Technologies.
