Agilent’s portfolio of gas and liquid sampling valve supplies are designed for complex applications.

• Gas sampling valves are available in Hastelloy C, a robust metal alloy ideal for corrosive or polar analytes, or in Nitrionic 60 stainless steel, which is the standard choice for most general applications
• Gas sampling valves are available as 4, 6, 10, or 14 port valves
• Sample loops for gas sampling valves are available from 0.025 μl to 10 ml
• General purpose liquid sampling valves are stainless steel, and available with 0.2 μl, 0.5 μl, or 1 μl

Gas and liquid sampling valves are most frequently used to sample gases or liquids 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 nonvalve injections (i.e., made by a typical liquid autosampler), use of capillary flow technology (CFT) is more straightforward. For more challenging valve applications, such as natural gas or transformer oil gas analysis, Agilent offers preconfigured analyzers for optimizing your GC system.
