| The BTU Gas Analyzer
GC is pre-plumbed and ready to resolve
N2, Methane, CO2, Ethane, H2O, Propane, iso- and normal Butanes
and Pentanes, and C6 plus backflush.
Unlike complicated and
timing-critical gas analysis configurations with
3-4 columns and 3-4 valves, the SRI BTU 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 30M. methyl silicone capillary column is located in the GC's
heated valve oven at a constant 40șC
temperature, while a stainless steel Hayesep D packed column is
temperature programmed from 30șC to 180șC using the SRI
resistively-heated "Virtual Oven" concept.
The main benefit of the BTU Gas Analyzer system is
simplicity, low cost, and low power consumption (300
watts). The BTU Analyzer can also determine the water
content of the gas sample. This GC can be operated from
a vehicle cigarette or power outlet using a power inverter and
laptop computer.
The BTU Gas Analyzer
can be configured with the TCD detector only, for
detection limits in the 200-500 ppm range. Other detectors
can be added for additional sensitivity.
