Maintenance Guidelines

You can achieve long and trouble-free performance from your Series 200 UV/VIS LC Detec-

tor by performing routine and preventive maintenance procedures.

Preventive maintenance ensures that your Detector will perform consistently at an optimal

level. To maintain the detector in its optimum operating condition, we recommend the fol-

lowing:

• Adhere to standard laboratory cleanliness practices.

• Use only high-purity solvents (preferably HPLC grade) for mobile phases. (Water should

be bottled HPLC grade, or filtered and deionized.)

• Filter the solvents to avoid particulate contamination and tubing blockages.

• Use only high-purity gases when drying contact areas.

• Ensure that all new tubing is passivated and thoroughly flushed before making detector

connections. (The tubing available from PerkinElmer is passivated.)

• Follow the short- and long-term shutdown procedures.

Routine Maintenance

In addition to preventive maintenance, you can perform routine maintenance on the detec-

tor, as needed, to keep it in proper working condition. Routine maintenance consists of

replacing the normal wear items such as the deuterium lamp and columns, whenever you

notice a degradation in performance. The exit window behind the flowcell should be removed

and cleaned periodically.

PerkinElmer replacement part numbers are referenced throughout this section; however,

when ordering replacements, refer to the HPLC Supplies Catalog or to a PerkinElmer Prod-

uct Description List.

To save time and money, refer to the Troubleshooting Guide in this chapter before perform-

ing any service. Use the Troubleshooting Guide to pinpoint the problem, then follow the sug-

gested solutions.

NOTE: For maintenance procedures that require removing the chassis from the external

cover, use the Allen key tool which can be stored inside the instrument, above the "Chassis

removal tool" label. The shaft of the tool is placed between the chassis and the cover, behind

the bulkhead for the plumbing unions on the left side of the insturment. The handle protion

of the tool is pointed down, between the two unions.

Always disconnect the AC line cord from the

AC outlet before opening the Series 200 UV/

VIS cover. Leave the AC line cord discon-

nected during all maintenance and parts

replacement procedures.
