Summary
A new system for multiple simultaneous gas-liquid chromatographic analysis is described. A commercially available gas chromatograph was modified to accommodate three wall-coated glass-capillary columns. A novel design of both the injection port and sample splitter allows the admission of equal portions of the sample into each of the three columns from a single injection. This provides the analyst either with data for the sample in question on three different liquid phases, or with a single result in triplicate if the same liquid phase is used on all columns. This presentation briefly describes the geometry of the inlet system; details will be published shortly. The performance of this system is illustrated with a simple example. In an artificial mixture, the quantitative GLC-data of 6 compounds obtained on three different columns were unequivocally correlated. A correlation number (CN) is derived which gives the maximum possible number of compounds that can be theoretically correlated in a mixture by the system described.
