ABSTRACT:
To avoid the problem of instrumental drift encountered when using an open-split interface between a temperature-programmed gas-liquid chromatography column and a mass spectrometer, the inert gas supplied to the open-split interface and the interface itself are heated to a temperature above the maximum temperature attained by the chromatography column during the analysis.
