Abstract
A method is provided for translating from a first method for performing gas chromatographic analysis to a second method for performing gas chromatographic analysis in a gas chromatography system without changing a peak elution pattern. Unlike the known method translation techniques that work only with the constant pressure gas chromatographic analyses, the invention can translate the gas chromatographic methods where column pressure and/or carrier gas flow rate change during the analysis by an arbitrary program.
