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, NOx, acetylene, propane, butanes, pentanes, and C₆-C₈. The MG#1 is very 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 2-meter Molecular Sieve 13X and a 2-meter Silica Gel.

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