3.1 Cautions on Operation
 Cautions Prior to Operation
• When high-sensitivity analysis is required, light the Xenon lamp ahead of time, taking into account
the time taken to achieve a stable baseline.
The guide for the stabilization time is 1 hour after the Xenon lamp has lit.
• Check that there are no liquid leaks at the flow cell and tubing connections.
 Cautions During Operation
Fig. 3.1
 Cautions After Operation
• Do not block the flow cell.
The fault that is most likely to occur with this instrument is contamination of the cell or clogging of the flow
cell.
After analyzing a high-density sample, flush the flow cell thoroughly with mobile phase to ensure that none
of the sample remains inside it. If a buffer solution is used as the mobile phase, flush with water after the
completion of analysis.
When the buffer solution dries, crystals will be generated, and these will cause clogging of the flow line in
the flow cell.
Front cover
• Make sure that the front cover is closed during
measurement.
If the front cover is opened during measurement the
baseline will fluctuate and this may hinder high-
sensitivity analysis. It may also increase noise.
