Two-Stage Gas Pressure Regulators

The quality of the CR gas regulator is critical to ensure optimum
performance of the instrument. A high quality two-stage pressure
regulator is absolutely essential, and it must be qualified for the purity
specification of the CR gas.
A gas regulator with two installed pressure gauges is not necessarily a
two-stage gas pressure regulator. Inform your local supplier that a
two-stage gas pressure regulator is absolutely essential and is a
requirement for stable performance of the iCAP Qnova Series
instruments.
The CR gas regulator should have a specification of 0.3 MPa (3 bar)
outlet pressure (max. 0.8 MPa [8 bar]), and it must fit the maximum
primary pressure specification of the CR 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.
Each country has a different standard outlet fitting for its gas supplies
and therefore each country will require a different regulator. Examples
for regulators are given by region in
listed, contact your local Thermo Fisher Scientific service office for
advice.
