The Multiple Gas Analyzer #2 GC system (MG#2) is pre-plumbed and ready to resolve H

, O

, N

, methane, CO,
ethane, CO

, ethylene, water, alcohols, propane, butanes, pentanes and C

. The MG#2 is similar to the
, except
that the MG#2 can measure water and alcohol in addition to the multiple gas compounds. This configuration has since
been superseded by the
series GCs, offering improved performance at a lower price.
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 H

, O

, N

, CH

and CO, at which point the molecular sieve carrier flow is turned off and the HayeSep-D carrier flow is turned on.
The HayeSep D column then separates all compounds in the C

-C

range. An
optional
capillary column in parallel with
the HayeSep-D can also be useful in separating the hydrocarbons out through C

any combination, depending on your application needs.
