Multiple Gas Analyzer #1 GC
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 100 - 300 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.

This MG#1 version includes:
- TCD detector
- FID-methanizer
- Molecular sieve 13X & silica gel columns
- Temperature programmable column oven
- 10-port gas sampling valve and loop
- 6 channel USB PeakSimple data system
- On-column injector
The FID measures the C1-C6 hydrocarbons, plus CO and CO2, which are converted to methane by the methanizer in the FID jet. The TCD measures hydrogen, oxygen, nitrogen, methane, and other compounds whose concentrations are at least 100 - 300 ppm.
Voltage: for 230VAC, use "8610-0070-2" or "8610-0071-2" or "8610-0072-2" or "8610-0073-2" (add "-2" to part number).
Options and upgrades include additional gas sampling valve, additional detectors, and additional columns.
