Abstract: A sensitive high resolution gas chromatography method for elution of volatile sample mixtures at controlled speed including intermittent stop flow operation. The method utilizes chromatographic exit column pressure above one atmosphere absolute up to and higher than 50 atmospheres absolute concurrently with controlled low velocity carrier gas movement within the column, The method facilitates stop flow operation for on line spectral analysis of eluted samples, and facilitates matching the speed of high resolution chromatograph operation to other on line analysis processes.
