摘要: A portable gas chromatograph assembly for detecting chemical species comprises a sample collector/injector introducing into the system, cryogenically enhanced stationary phase focusing zone reducing band width of introduced sample, one or more resistively heated conductive film clad, fused silica capillary columns and associated support structure separating mixture its individual components, column temperature control electronics, detector registering components.
