In the PlasmaQuant PQ 9000, argon is used as a gas for the torch, the nebulizer and for
purging the spectrometer. The purge gas is then directed via the cone for axial observation as a
counter gas to avoid a heavy load being placed on the cone and plasma window by the plasma
torch. Oxygen can be optionally connected as an additive gas.
Plug-in connectors are used for the gas connections of the PlasmaQuant PQ 9000. Hoses are
pushed into the connector as far as possible and are thus securely fastened. To release the
connection, you have to push the blue ring inwards and pull the hose out at the same time.

The hoses for cooling water are also equipped with quick couplings. When connecting the
hoses, the connecting pieces on the hoses are pushed into the sockets all the way until they
