4.3 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.
After plasma has been turned off for at least 30 seconds turn off the chiller, following the
manufacturer's instructions (turning off the chiller by removing the power can often cause
breakages!)
Allow five minutes after switching off the plasma before disconnecting the electrical power or
other supplies to the instrument, or accessories.
The tension on the pump platens should be released to preserve the life of the pump tubing.
NOTE: For the iCAP 7600 the valve and tubing should be rinsed and then purged of solutions. To
purge the 7600 Sprint Valve - open the Sprint Valve Configurator. Verify both Sample and Rinse
probes are in air, confirm (or set) Load, turn On the Vacuum Pump Control for several seconds.
When the Sample Loop and Valve are emptied turn Off. See the Qtegra section below.
