摘要： A gas chromatography instrument is provided that is capable of analyzing samples both quickly and accurately. The detector includes a first unit and a second unit that alternate between collection mode and desorption mode. This allows one unit to collect the sample, while the other unit desorbs another sample before the units switch operations. The alternating collection and desorption modes allows the detector to generate a data point approximately every thirty seconds, with each alternating unit.
