Abstract

Improved instrumentation facilitates on‐column injection of up to several hundreds of microliters onto GC capillary columns. It incorporates an autosampler with adjustable injection speed, a standardized precolumn system, an early vapor exit, and software that models evaporation of a given solvent at the flow and temperature conditions chosen by the user. The software calculates the appropriate injection speed, guides the autosampler correspondingly, and closes the vapor exit at a moment leaving in the precolumn the amount of unevaporated solvent that is selected by the user. © 1995 John Wiley & Sons, Inc.
