8 Instrument Maintenance
Instrument maintenance is quite simple on the XDS MultiVial 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.
The sampling window should be kept clean to prevent loss
of signal. (This is especially important with high-absorbance
samples.) Clean with a dampened, soft, non-linting tissue.
Remove all 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 MultiVial Analyzer. Such equipment can produce spectral
disturbances that are visible in diagnostics scans, and may affect analytical results.
