Separation efficiency versus column length. An experimental study with capillary columns


Grob, K; Grob, G (1969). Separation efficiency versus column length. An experimental study with capillary columns. Journal of Chromatographic Science, 7(8):515-516.

Abstract

The columns of different length used for studying the relation between HETP and column length are supposed to exhibit identical characteristics per meter. In the laboratory this condition cannot be rigorously fulfilled. The best approximation probably consists in starting the work with a relatively long capillary column followed by running shorter parts obtained by progressive cutting of the original column. Based on this procedure a marked increase of HETP with increasing column length is observed
