ABSTRACT:
The present invention comprises a method for expediting the analysis of a plurality of samples, preferably using gas chromatography. A specific embodiment comprises a dual isothermal heated zone configuration for use in combinatorial chemistry. This involves partitioning the samples into two isothermal zones, allowing detailed analysis of light components in a lower-temperature zone while heavy components are handled in a higher-temperature zone.
