Sample introduction system maintenance
WARNING
Risk of eye and skin injuries due to UV and electromagnetic radiation!
Plasma emits UV radiation and high-frequency electromagnetic radiation which can
cause serious eye and skin injuries as well as other health problems.
Before removing the glass components of the sample introduction system for
maintenance work, always extinguish the plasma from the software.
CAUTION
Risk of injury from breaking glass!
The standard sample introduction system components are made from high purity
quartz glass and susceptible to breakage if handled roughly. Always use care when
installing, removing, or cleaning these items!
NOTICE
Risk of contamination!
Do not use compressed air to dry the glass components. Compressed air often contains
oil vapor and the oil will contaminate the glass components.
It is safe to leave the power to the ICP-MS on when maintaining the glass components
of the sample introduction system.
The glass components of the sample introduction system (torch, transfer tube, spray
chamber, nebulizer) may require periodic cleaning if extended rinsing does not
eliminate contamination. The glass components can be cleaned in almost any solvent
or acid bath mixture (except for HF acid) without damaging them. Typically soaking
the components overnight in strong acid or detergent followed by extended rinsing in
deionized water is suitable. Remove all fittings and connectors from the glassware
before soaking them.
All glassware parts except the nebulizer can also be cleaned in an ultrasonic bath as
well.
