of resting on the instrument.

ICP Expert II software running. You may switch off the printer, monitor and any
accessories if desired.

during an unexpected shutdown.

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.
