This instrument comprises a Shimadzu GC2010 plus Gas Chromatograph with a quadrupole mass detector. The mass detector has an extremely fast scan speed of 20,000 u/sec, allowing for comprehensive GC x GC MS analysis.
The picture shows an attached AOC-20i autoinjector (12 sample capacity) with an AOC-20s tray, which increases sample capacity to 150.
Generally, helium is used as the carrier gas for GCMS applications. However because of the increasing scarcity of He, hydrogen gas can also be used. H2 gives advantages in analysis speed (better Van Deemter curve parameters) but this should be weighed against the higher safety risks with this explosive gas.
