Summary

The characteristics of gas chromatography peaks arising from various compounds when the column flow is reversed has been studied. It is shown that all compounds are eluted after reversal of the flow with the peak maximum at a time equal to or less than the time of flow reversal. The half width of the reverse peak is determined by a constant related to the number of plates in the column, and the square root of twice the time of flow reversal multiplied by the square root of the time of emergence of the compound when run in the forward direction. The method appears applicable to the concentration of trace high boiling impurities in any matrix in which the bulk components can be rapidly eluted through a suitable column.
