• Wide range of stationary phases offers orthogonal separations. • High thermal stability maximizes system ruggedness and sensitivity. • Unrivaled column inertness for accurate analysis of active compounds. • 0.15, 0.18, and 0.25 mm ID formats accommodate varying sample capacities, speeds, and detectors. • Secondary columns come in convenient 2 m lengths for economical method development. GCxGC is a powerful multidimensional GC technique that combines two independent separations to accurately analyze highly complex samples. GCxGC involves two columns with differing (orthogonal) stationary phases that are press-fitted together in series and separated by a modulator. The first (primary) column performs a separation, and its effluent is continually focused and “injected” by the modulator ont...Read more
