4.5 Care and maintenance
Instrument care
The 837 IC (Eluent/Sample/Combi) Degasser requires adequate care.
Excessive contamination of the instrument could interfere with its func-
tions and reduce the working life of the really robust mechanism and
electronics.
Spilt chemicals and solvents should be removed immediately. The con-
nections on the rear panel (and the mains connection in particular)
should be protected against contamination.
Although the design prevents liquid penetration to a great extent, if
aggressive media should enter the housing then pull out the mains
plug of the 837 IC (Eluent/Sample/Combi) Degasser immediately, in
order to prevent massive damage to the instrument’s electronics. In
such a case please contact the Metrohm Service Department.
The instrument may only be opened by specialized staff of Metrohm.
Maintenance by Metrohm Service
The maintenance of the 837 IC (Eluent/Sample/Combi) Degasser

terval between servicing.

on the maintenance and servicing of all Metrohm instruments.
