The Multiple
Gas Analyzer GC is pre-plumbed and ready to
resolve H2, O2, N2, Methane, CO, Ethane, CO2,
Ethylene, NOX, Acetylene, Propane, Butanes,
Pentanes, and C6 through C10.
Unlike
complicated and timing-critical gas analysis
configurations with 3-4 columns and 3-4 valves,
the SRI Multiple Gas Analyzer uses just a single
10 port gas sampling valve and two columns, and
is very tolerant of valve timing variations or
operator adjustments. The Molecular Sieve column
is located in the GC's heated valve oven at a
constant 100ºC temperature, while the Silica gel
column is temperature programmed from 40ºC to
300ºC in the main column oven. The Silica gel
column can optionally be replaced by a Porapak
column for H2O analysis, or for other polar
analytes.
The main
benefit of the Multiple Gas Analyzer system is
simplicity, since competing systems are often
vastly more complex and tricky to operate. The
only negative is that C4 and C5 isomers do not
completely resolve on the silica gel column.
The Multiple
Gas Analyzer can be configured with the TCD
detector only, for detection limits in the
200-500 ppm range, and TCD-Methanizer-FID for
improved detection limits ( 5 ppm ) for CO, CO2
and all hydrocarbon peaks. Also available is the
TCD-HID detector combination for detection
limits in the 10 ppm range for all analytes
including hydrogen.
