4.1.3 Gas supply
WARNING
Danger of explosions! Hydrogen is highly combustible. Oxygen is a
powerful oxidizer.
Further, any leak in the gas supplies (except for oxygen) can result in an oxygen
-
deficient atmosphere which can cause asphyxiation!
The operator must ensure that the connector type used on the outlet side of the gas
pressure controller
is adequate for the national requirements that apply.
The operator must carry out the necessary safety leakage tests weekly on all gas
supplies up as far as the device. For this, possible pressure losses from closed systems
and lines under pressure are to
be determined. Any leak is to be localized and
corrected immediately.
If the gas is supplied by pressure cylinders, these must be secured to the wall in an
upright position with cylinder mounts outside the laboratory space.
The following gases are used in conjunction with the PlasmaQuant MS
 Argon as plasma gas, auxiliary gas, sheath gas (optional) and nebulizer gas
 Helium and Hydrogen as gases for the integrated Collision Reaction Cell (iCRC)
 Nitrogen and Oxygen as additive gases to the auxiliary gas (Nitrox only)
Do not connect any other gases than those specified to the correct inlet fittings. Use
only instrument-grade gases with your spectrometer. Do not exceed the maximum
inlet pressures.
Argon gas from the gas supply regulator flows to the ICP-MS gas box module through
a 3 m PTFE hose supplied with the instrument. If other hose lengths are preferred,
please contact the service department at Analytik Jena.
