5 "OUT" cooling water outlet
Argon is used for the torch, the nebulizer and for purging the spectrometer. The purging
gas is then directed via the cone as a counter gas for axial observation to avoid heavy
strain to the cone and plasma window via the plasma torch. Oxygen can be optionally
connected as an auxiliary gas.
Plug-in connectors are used for the gas connections. Hoses are pushed into the connec-
tor as far as possible and are thus securely fastened. To release the connections, push
the blue ring inwards and pull the hose out at the same time.
Figure 9 Plug-in connectors for gas connections
The hoses for cooling water are also equipped with quick couplings. When connecting
the hoses, push the connection pieces on the hoses into the sockets all the way until
they engage with a click. When releasing the connections, push the ring on the socket
back and pull the hose out of the connection. The valves in the quick couplings prevent
the cooling water from flowing out.
