iCAP RQ Pre-Installation Requirements Guide (P/N BRE0009927, Revision A)
5-7
Plasma and Cooling Gas
The argon supply to the iCAP RQ instrument must be stabilized. The
gas pressure regulator must be qualified for the purity specification of
the plasma gas, see
.
Using a high quality two-stage regulator is recommended, see
for suppliers of pressure regulators.
NOTICE
The plasma gas regulator must have an outlet pressure of max.
1 MPa (10 bar), and it must fit the maximum primary pressure
specification of the argon gas laboratory supply. Check whether your
maximum primary pressure is 30 MPa (300 bar), 23 MPa (230 bar), or
20 MPa (200 bar), and choose accordingly.
▲
Connection of the laboratory argon supply to the iCAP RQ instrument
is made via a push-in fitting. A recommended set-up for the argon
supply is shown in
. 3 m polyurethane tubing will be supplied
with the instrument.
