    Abstract

    An approach is given using the Perkin-Elmer PEP-2 chromatographic Data System [1] to combine data from both columns in a gas chromatograph. The Interactive Programming Module (IPM) option [2] is required. Program language is Interactive Programming Language (IPL). The component of interest is not always separated adequately from interfering substances in a single column analysis. Thus, a sample is frequently analyzed under more than one set of chromatographic conditions. The component of interest must be identified on each column to give a positive result. When sample volume is large it is convenient to have on-line data processing, such as the PEP-2 dedicated system. A printout of computed results from each column is quantitatively superior to manual chromatogram evaluation techniques. Combining all results for a sample in one report is the approach applied by the authors to a dual column configuration described by Adams [3]. If a drug is identified on both columns, further confirming analyses are pursued.
