}
Confirm the prompt to switch off the purging gas for the spectrometer with [Yes] if it
must be switched off.
}
If work is only interrupted for a short period (up to 30 min.): Do not switch off the
purge gas. This saves the wait time for the spectrometer to be sufficiently purged
during the ignition process.
}
Wait for the message that the device and the cooling can be switched off.
}
Switch off the emission spectrometer, and, if applicable, the sampler via the respec-
tive power switch.
}
Unclamping the pump hoses from the hose pump:
– Release the clamping levers so that the clamping brackets no longer press on the
hoses.
– Pull the hose stoppers on the left side of the pump from the restraint.
}
When using the sampler, unclamp the pump hoses in the same manner.

Switching off the device via the plasma deactivation switch in an
emergency
Immediately switch off the plasma using the plasma deactivation switch on the left-
hand side of the device if one of the following faults occur:
¡
A rattling sound can be heard
¡
A ring plasma forms (plasma forms only in the induction coil)
¡
The quartz glass of the external torch tube glows red-hot.
¡
No communication with the PC
Wait at least 30 s for the emission spectrometer to cool down before switching it off via
the power switch.
After manually switching off the plasma or an automatic shutoff by one of the device's
safety circuits: Check that all requirements for switching the device on are met before ig-
niting the plasma again.

Starting a measurement routine
A method must be developed before a measurement can be made. The application team
is on hand to offer support. Please observe the information provided in the operating in-
structions of the ASpect PQ program.
}
Switch on the emission spectrometer and ignite the plasma.
