#SRI-8610-0270-1, #SRI-8610-0270-2


  • Separates multiple gases with a single injection, including water
  • Simpler than other multi-gas systems
  • Very tolerant of user adjustments

The basic MGA #2 includes:

  • TCD detector
  • 10-port gas sampling valve, valve oven, and dual loops
  • MoleSieve and Hayesep-D packed columns
  • 1-channel Peaksimple data system

The optional MGA #2 upgrade includes:

  • TCD / FID-methanizer or TCD / HID detectors
  • 10-port gas sampling valve and valve oven
  • MoleSieve and Hayesep-D packed columns
  • 4 or 6-channel Peaksimple data system

Options & Upgrades: additional detectors, 6 channel USB PeakSimple data system



SRI full-featured Portable GCs are ideal for use in the field, as well, and they are equally comfortable on a lab bench. You can customize a GC system to meet your specific analytical needs with a wide range of injectors, detectors, and accessory options.

Due to the popularity of some configurations, a number of pre-configured GCs are offered satisfying a wide range of common analytical applications. In some cases, the preconfigured GCs are less expensive than the identical hardware assembled "a la carte." Each of the preconfigured GCs may be further customized (except the educational GC systems).

Check out these popular pre-configured systems below, or configure your own system to meet your needs.

The Multiple Gas Analyzer #2 GC system (MG#2) is pre-plumbed and ready to resolve H2, O2, N2, methane, CO, ethane, CO2, ethylene, NOx, water, alcohols, propane, butanes, pentanes and C6+. The MGA#2 is similar to the MGA#1, except that the MGA#2 can measure water and alcohol in addition to the multiple gas compounds.

To separate such a wide variety of peaks without co-elution, the MG#2 turns on the carrier gas flow to each column at different times during the run. This allows the Molecular Sieve column to complete the separation of H2, O2, N2, CH4 and CO, at which point the MoleSieve carrier flow is turned off and the HayeSep-D carrier flow is turned on. The HayeSep-D column then separates all compounds in the C1-C6 range. A capillary column in parallel with the HayeSep-D can also be useful in separating the hydrocarbons out through C20. Detectors can be TCD, HID, FID, or any combination, depending on your application needs.

Hot tips:

Up to five injectors can be mounted on the 8610c GC Mainframe. Due to limited space, only a single injector can be mounted on the 310 GC Mainframe.

In order to add a second injector, of any type, additional cold on-column injector hardware must be added first. This hardware is then upgraded to the appropriate injector type.

Preconfigured gcs take advantage of batch manufacturing, offering a lot of gc power at very reasonable pricing.
