ABSTRACT:
Chromatographic analysis of the volatile components of a liquid having both volatile and nonvolatile components is accomplished by vaporizing the volatile portion of a liquid sample in a hollow tubular vaporizing column and subsequently analyzing the thus-vaporized portion of the sample. The nonvolatile components of the sample are retained in the vaporizing column during vaporizaton and then are removed by backflushing the vaporizing column with a preselected volume of a liquid solvent.
