•

Front cover, lamp cover, or flow cell cover is missing

Optical components are sensitive to temperature and light. Do not operate the
Dionex PDA unless the front cover, lamp cover, and flow cell cover are in
place.

•

Crimped or plugged tubing

Over time, tubing may become pinched off and plugged. Periodically check
all tubing and replace as needed (see

•

Flow cell installed incorrectly

Check that the cell is inserted straight into the optical bench and is fully
seated.

•

Inappropriate rise time

In general, the rise time should be approximately 25% of the peak width at
half-height of the narrowest peak of interest. See

for more

information.

•

Detector exposed to high vibration

Optical detectors are sensitive to vibrations. Make sure the Dionex PDA
installation site is vibration-free.

•

Filter paddle has malfunctioned

If you have recently autozeroed the detector, check the Chromeleon Audit
Trail. If the “Filter wheel sensor could not detect blocked position.” or “Filter
wheel sensor could not detect open position.” message is displayed, see

for instructions.

•

Pump needs priming and/or maintenance

If the baseline noise is synchronized with the pump stroke, reprime the pump
and clean the piston seals and/or check valves. Refer to the pump user’s
manual for instructions.

•

Negative absorbance level is too high

Baseline noise may increase as the negative absorbance increases. If the noise
is unacceptable, reduce the negative absorbance level (see

).
