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 MG#2 is similar to the MG#1, except that the MG#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.
