Introduction
This chapter describes the routine maintenance procedures required to keep your
instrument in proper working condition and to ensure the highest possible level of
performance. It includes maintenance checks that should be done on a daily basis and
maintenance procedures that should be done periodically depending on instrument
use. This chapter is divided into several sections, each section covering maintenance
procedures for a particular component of the system.
You should perform only the maintenance procedures described in this chapter.
Record your daily maintenance procedures in the
ICP-OES Maintenance Log (Part.
No. 09936225) . If additional maintenance is required, contact a PerkinElmer service
engineer. This instrument requires no specified inspection or preventive
maintenance to ensure the continuous functioning of its safety features.
Daily Checks
The following maintenance procedures should be done on a daily basis. Make sure
to inspect and replace any hoses which show signs of wear because their failure
could cause a hazard.
Daily Cleaning
At the end of each working day, it is recommended that you flush out the sample
introduction system for five minutes with the plasma on. After analyzing aqueous
solutions, flush with deionized water or a 2% nitric acid solution, followed by
deionized water. After analyzing organic solutions, flush the system using clean
solvent. Also clean the spectrometer housing using a mild lab detergent.
Argon Supply
Make sure that an adequate supply of argon is available and connected to the system.
Check that the argon tank(s) have sufficient pressure, and that a spare tank is ready
if necessary. Argon can be purchased from local suppliers. The argon for use with
ICP systems should be 99.996% pure.
Caution
Before using any cleaning or decontamination methods except those
specified by the manufacturer, users should check with the manufacturer
that the proposed method will not damage the equipment.
