The 310 Soil Gas GC is similar to the Environmental GC, except that it is more compact and does not include a Purge & Trap. This configuration has been approved by the Japanese Ministry of the Environment for the analysis of VOCs in soil and water samples by direct headspace injection. The only sample preparation required is to enclose the soil sample with water in a vial, and heat it or let it equilibrate at room temperature, then take a headspace sample and inject it into the On-column injector.

Sensitive and non-destructive, the PID detector responds to aromatics and any molecule with a carbon double bond. The combination FID/DELCD detector may be operated in regular (simultaneous operation) or high sensitivity mode (DELCD only, FID hydrogen off). The FID responds to linearly all hydrocarbons, while the DELCD responds to chlorinated and brominated molecules. The built-in air compressor provides a nearly silent supply of FID combustion air, eliminating the need for air cylinders. The 30-meter, 0.53mm capillary column can efficiently separate hydrocarbons up to C₄₀+.
