Gas supply
The following gases are used with the emission spectrometer:
¡
Argon as the gas for the torch (plasma gas, auxiliary gas, nebulizer gas)
¡
Argon as the purging gas for the spectrometer and as the cone gas
¡
Oxygen as an auxiliary gas
Optionally for selected applications, such as with some organic solvents, oxygen can be
used as an addition to the nebulizer gas.
The standard length of the hose is 3 m. If different hose lengths are required, please
contact customer service.

Exhaust unit
The exhaust unit must be switched on during operation of the emission spectrometer.
Whether the exhaust is switched on is checked via the device-internal safety circuits be-
fore plasma ignition. The plasma will not be ignited if a fault is present.
Correct exhaust ventilation requires sealed connection of a suction hose to the smoke-
stack of the emission spectrometer.
The exhaust unit is to dissipate health-hazardous gases created during plasma opera-
tion such as ozone or nitrous oxides. Use an exhaust unit made of heat- and corrosion-
resistant material. The first 6 m of the exhaust system must be made of metal or a heat-
resistant material (> 85 °C). The first meter must be made of a flexible material to reach
the device from above.
