  • Patent number: 5096471
    Abstract: Gas chromatography apparatus and procedures are described which enables gas chromatography to be carried out more rapidly than in accordance with prior art techniques and further enables chromatogram peaks caused by materials of interest from being obscured due to their super imposition upon high peak long durations produced by another component of peaks in an organic mixture. Reductions in chromatography evaluation time are achieved through employing a vacuum pump which caused backflushing of a very short column after materials of interest have been eluted but before higher boiling points components of the mixture have eluted. Backflushing is carried out using a vacuum pressure source which when used with a short column, permits rapid and complete backflushing. The chromatography system according to this invention allows simultaneous column backflushing while a new sample is being collected in a cooling chamber for cryofocussing for a subsequent injection.
