Splitless injection on capillary columns, Part II. Conditions and limits, practical realization


Grob, K; Grob, G (1969). Splitless injection on capillary columns, Part II. Conditions and limits, practical realization. Journal of Chromatographic Science, 7(10):587-591.

Abstract

Our procedure of direct splitless injection on capillary columns is based on the choice of column temperature for injection. Under appropriate conditions a marked concentration effect is observed, i.e. the eluted band is more concentrated than the injected one. The dependence of this effect on column temperature, injection time, sample size, and other variables has been studied experimentally. A solvent bypassing technique has been developed which allows the performance of trace analysis on capillary columns
