Cleaning the Prism



WARNING

◇

Handle all harmful substances with extreme caution.

Fully understand a sample's properties before applying to this instrument.

Ensure no harmful sample substances are present when dismantling.



CAUTION

Temperature of the cleaning liquid

◇

Cleaning liquids up to 160˚C can be used for CIP or SIP. The momentary
difference between the sample liquid temperature and the cleaning liquid
temperature must be no more than 80˚C.
When using cleaning liquids at temperatures over 160˚C, the power
switch must be turned off.

When samples flow through the sample inlet for a long period of time, it is possible that solids or oils adhere

to the surface of the prism, and this build-up can affect readings.

Cleaning by hot water or alkaline liquid, called CIP cleaning, is recommended for removal of prism build-up.

The PRM-

100α is designed for cleaning with solutions up to 160˚C.

When cleaning with solutions hotter than 160˚C, the instrument must be powered off.
Additionally, the difference in temperature between the sample and the cleaning solution can be no greater
than 80˚C.
If a greater difference is necessary, run a warmer solution through the sample inlet for a few minutes before

applying the cleaning liquid.

If matter adhering to the surface of the prism cannot be removed by such cleaning, it is necessary to clean

the surface of the prism directly. Follow these steps:

①

Detach the detection section from the sample inlet unit.

②

Clean the surface of the prism using soft tissue paper moistened in lukewarm water or ethyl alcohol.

For a liquid containing oils and fats, wipe out with soft tissue paper moistened in ethyl alcohol.

Never scrub the surface of the prism with a hard object, otherwise flaws will develop.

③

Remount the sample inlet unit in its original position.
