4 Operation and maintenance
4.1 Maintenance
CAUTION
The conductivity detector must not be opened!
WARNING
When rinsing the detector without column, the pressure must not
exceed 5 MPa. In order to ensure this, the maximum pressure of the
high pressure pump must be set to 5 MPa in MagIC Net.
If the conductivity detector is blocked, you should first of all check
whether the blockage results from the capillary ends being pressed
together too firmly. In this case, shorten the detector inlet capillary (1-3)
or the detector outlet capillary (2-2) by several millimeters.
If this does not help, the conductivity detector can be rinsed against the
normal flow direction. For this, connect the high pressure pump to the
detector outlet capillary (2-2) and rinse - the pressure may not exceed
5 MPa.
4.2 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.
