Operation
3 Turn off the Peltier by choosing Peltier Off from the Analyze menu.
CAUTION
The ICP-OES gas control unit supplies uninterrupted gas purge to the
polychromator assembly to minimize the ingress of moisture. It is strongly
recommended that gas supplies be left on at all times except during long periods
of non-use.
4 Switch off the mains power switch (the green light will go off). This will turn off
the complete instrument, including the Peltier (if not done so manually earlier)
as well as the polychromator thermostating system.
5 Loosen the peristaltic pump tubes by releasing the pressure bars and lift the
tubes out of the grooves. To do this:

6 Switch off the water cooler, laboratory exhaust system and any accessories
(where applicable), and shut down the argon gas supply at the cylinder.
7 Exit the ICP Expert II software, if it is no longer required, by choosing Exit from
the File menu. Switch off the printer and monitor.
8 Restarting the instrument will take several hours due to gas purge and
polychromator thermal stabilization time.
NOTE
If the instrument is not going to be in use for a period of time the torch, cone, snout
and torch compartment should be cleaned of any deposits, dirt or residue.
