Instrument Maintenance
Instrument maintenance is quite simple on the XDS Rapid Liquid Analyzer. The optical enclosure is
sealed to prevent contamination of critical parts, which keeps maintenance to a minimum. A diagram
of the internal parts is shown, primarily for user information.
8.1 Overview
DO NOT attempt to open the optical enclosure. There are no user-serviceable parts inside. Damage is
not covered under warranty.

This is a diagram of a top view of the inside of the instrument, showing the relative location of major
components. Do not attempt to open the instrument enclosure unless directed to do so by trained
Metrohm service personnel. The instrument should be kept clean at all times. If it becomes dusty or
dirty, wipe it with a damp, soft cloth to restore the finish.
Sampling areas should be kept clean to prevent loss of signal. In
the Liquid Analyzer, avoid spills or debris inside the sampling
drawer, which could soil the cuvettes when they are inserted
into the holder.
Clean with a dampened, soft, non-linting tissue. Remove all
liquid, surface deposits and dust.
Periodically verify that no equipment has been placed nearby that might produce vibration or impacts
that could be transferred to the XDS Rapid Liquid Analyzer. Such equipment can produce spectral
disturbances that are visible in diagnostics scans, and may affect analytical results.
8.2 Fan Filter Replacement
The fan filter should be inspected at least monthly. (If installed in a dusty or dirty environment, it
should be checked weekly or twice-weekly.) We recommend that instrument power be turned off
before changing the filter. The filter is changed as follows:
