Close the worksheet by clicking ‘Close’ from the ‘File’ menu but leave
the ICP Expert II software running. You may switch off the printer,
monitor and any accessories if desired.
Ensure that the powersave option on your PC is disabled (this will
prevent the shutdown of your hard disk). If this option is not
disabled, you could lose data during an unexpected shutdown.
WARNING
Noxious Fumes
Inhalation danger. The exhaust system MUST remain on if the gas supplies
are on.
Using Shutdown Mode
To shut down your instrument:
1
Rinse the spraychamber by aspirating water for a few minutes.
NOTE
When running organic samples it may be necessary to disconnect the
spraychamber and clean and dry it thoroughly between analyses.
2
Extinguish the plasma by clicking the
Plasma Off
icon, pressing
F4 on the keyboard or choosing
Plasma Off
from the
Analyze
menu. The peristaltic pump stops automatically when the plasma
is extinguished.
NOTE
The yellow Plasma emergency off button, located next to the mains power
switch on the front of the instrument, is designed to be used only in an
emergency—for example if the torch is melting. It is not intended to be used
every time you want to extinguish the plasma.
If used to extinguish the plasma, you will need to reset the Plasma emergency
off button to the ‘on’ position before the plasma can be re-ignited.
3
Turn off the Peltier by choosing
Peltier Off
from the
Analyze
menu.
