Preparing the System for Use

If the gas supplies have been switched off, the optical components should be
purged for at least one hour before powering the instrument.
If the instrument is switched off, allow at least two hours after restoring power to
thermally stabilise the instrument before the chiller is turned on.
A blank sample should be aspirated for ten minutes to allow the instrument to fully
stabilise before analysis.

Instrument Shut-down

After an analysis is finished a blank sample should be aspirated for five minutes to insure
the sample introduction part have been rinsed of sample. To remove the blank sample
deionised or distilled water should be aspirated for a further minute.
When organic solvent based samples are being analysed the final rinse should be the
pure solvent. Air should be aspirated for two minutes to remove organic vapours.
After completing the above the plasma should be turned off. The optical components will
move to a parked position after about thirty seconds.
Allow five minutes after switching off the instrument, or accessories, before disconnecting
the electrical power or other supplies.
