Additional Gas
Depending on the application, a variety of additional gases may be
employed. The use of mass flow controllers is required when working
with additional gases.
The gas supply to the additional mass flow controllers of the instrument
must be stabilized. The gas pressure regulator must be qualified for the
purity specification of the respective gas. Thermo Fisher Scientific
recommends using a high quality two-stage gas pressure regulator.
Argon, Pure Helium or Mixtures with Argon
For some applications, the use of additional gas is beneficial. The gas
requirements are detailed in
Table 5-11 .
NOTICE
The additional gas regulators must have an outlet pressure of max.
0.1 MPa (1 bar), and they must fit the maximum primary pressure
specification of the additional gas laboratory supplies. Check whether
your maximum primary pressure is 30 MPa (300 bar), 23 MPa
(230 bar), or 20 MPa (200 bar), and choose accordingly.
