Gas sampling valves are most frequently used to sample gases in constantly flowing streams such as those in chemical reactors, chemical transfer lines, natural gas processing, and fermenters. Sampling valves can also be used to enable multidimensional GC techniques such as backflush, Deans switching, or 2D-GC (GC x GC). However, for non-valve injections (like those made by a typical liquid autosampler), use of capillary flow technology (CFT) is more straightforward.
