larly after having made any modifications. If leakage is detected, this has
to be eliminated immediately so as to prevent instrument damages.
If the necessity to clean the oil filter should arise periodically as a result of
analyzing liquefied gases with nonvolatile components, the rinsing with
solvent (see Chapter 4.2.8, page 31) option is particularly recommended.
Given the automated rinsing, no mechanical work is required on the gas-
carrying system. The risk of leakage is thus eliminated. If the filter is
cleaned manually, the system's tightness should be checked again after
the filter is built in, like after any changes to the gas system.
NOTE
The nitrogen inlet's check valve, which is a safety feature in case of an
operating error, must be subjected to a functional check at least once a
year. It has to be checked whether an additional check valve is required
for the nitrogen supply.
5.1.2 Maintenance by Metrohm Service
Maintenance of the 875 KF Gas Analyzer is best carried out as part of an
annual service, which is performed by specialist personnel of the Metrohm
company. If you are frequently working with caustic and corrosive chemi-
cals, we recommend a shorter maintenance interval.
Metrohm Service offers every form of technical advice for maintenance
and service of all Metrohm instruments.
5.2 Quality Management and validation with Metrohm
Quality Management
Metrohm offers you comprehensive support in implementing quality man-
agement measures for instruments and software. Further information on
this can be found in the brochure «Quality Management with
Metrohm» available from your local Metrohm agent.
Validation
Please contact your local Metrohm agent for support in validating instru-
ments and software. Here you can also obtain validation documentation
to provide help for carrying out the Installation Qualification (IQ) and
the Operational Qualification (OQ). IQ and OQ are also offered as a
service by the Metrohm agents. In addition, various application bulletins
are also available on the subject, which also contain Standard Operat-
ing Procedures (SOP) for testing analytical measuring instruments for
reproducibility and correctness.
