5 Maintenance information
The 832 KF Thermoprep does not need a lot of care. Ensure that it does
not become excessively dirty and is not exposed to corrosive atmos-
pheres.
• Renew used-up molecular sieve in good time. The molecular sieve
should be exchanged as soon as increased drift values occur in the
Karl Fischer cell.
• Rinse the tubing and the distributor occasionally and carefully dry
the tubing.
• Clean the oven compartment at regular intervals.
• Replace the dust filter on the rear panel when necessary.
6 GLP validation
Each instrument produced by Metrohm undergoes a rigorous quality
control check before delivery.
GLP (Good Laboratory Practice) requires, among other things, that the
precision and correctness of analytical instruments are checked at
regular intervals by using SOPs (Standard Operating Procedure).
