The Hiden HPR Series of mass spectrometer-based gas analysers
is further expanded to include analysis of static off-line gas
samples in addition to the more routine conditions of dynamic flow.
New additions include the HPR-70 benchtop system for gas
composition measurement of individual discreet samples as small
as 0.1 sccm, the gas preparation stage including selectable
cascade volumes for pressure optimisation over a wide spread of
sample volumes and sample pressures. Samples will normally be
acquired and contained off-line, the container having an isolation
valve or breakseal for direct connection to the mass spectrometer.
The HPR-90 system uses similar mass spectrometer stages
together with a customised inlet system specifically configured for
analysis of gases trapped within enclosed volumes. Commonly
the enclosure material will be glass, metal, plastic or ceramic,
examples being lighting bulbs and tubes, electronic packaging, gas
bubbles in glass. The item is totally enclosed within a UHVcompatible
evacuated vacuum vessel and the system is equipped
with appropriate cracking or drilling facilities to enable release of
the gas sample for immediate analysis. Package volumes ranging
from 10 litres down to sub-millilitre are accommodated.
Systems offer a choice of either manual or automated operation
and include multiple calibration routines for data quantification
enabling measurement of low-level gas components to the subppm
