13. Cleaning the Prism
◇ Before running hazardous substance(s) through any system,
necessary precautions should be taken to ensure the safe
handling of the hazardous substance(s). If using a sample inlet
unit, use caution when disconnecting the CM-BASEα unit.
◇ Before cleaning the prism, be sure to turn off the power
(DC24V).
① Detach the clamp band that connects the main unit to the sample inlet unit, piping or
tank.
② Clean the prism surface carefully with a soft tissue soaked with warm water or ethyl
alcohol. If the sample solution contains oil or grease, use ethyl alcohol to ensure the
prism surface does not develop a film. Development of a film on the prism could
cause erroneous measurements.
③ NEVER clean the prism with an abrasive material. Cleaning the prism with an
abrasive material could cause scratches on the prism which could lead to erroneous
measurements.
④ After cleaning is complete, re-attach the CM-BASEα unit to the sample inlet unit,
piping or tank.
Clean this prism surface carefully with a soft
tissue soaked with warm water or ethyl
alcohol.
