The SRI Multiple Gas Analyzer #1 GC System (MG#1) can separate multiple gases with a single injection. It is pre-plumbed and ready to resolve H₂, O₂, N₂, methane, CO, ethane, CO₂, ethylene, acetylene, propane, butanes, pentanes and C₆, if desired. The MG#1 is tolerant of user adjustments and timing variations because it is simpler than other multi-gas capable systems. Unlike complicated and timing-critical gas analysis configurations with three or four columns and three or four valves, the MG#1 uses a single 10-port gas sampling valve and two packed columns: a 6 foot long molecular sieve 13X packed column, and a 6 foot long silica gel packed column.

The basic Multiple Gas Analyzer #1 is equipped with a TCD detector for detection limits in the 200 - 500 ppm range. The second option is a TCD-Methanizer-FID configuration, which provides 5 ppm detection limits for CO, CO₂, and all hydrocarbons. The third option is a TCD-HID configuration for detection limits in the 10 ppm range for all analytes.
