d the stationary phase may be a solid or a liquid. There are thus four main sub-divisions of the chromatographic process, as set out in Table 1.1. The system is called adsorption chromatography if the stationary phase is a solid, and partition chromatography if it is a liquid.978-0-412-20810-2978-1-4899-3360-7

Liquid-phase Chromatography on Columns,ping together a number of different physical systems, and the common feature is the practical technique which is used; the broad sub-divisions were described in Chapter 1. The solid column packing may be itself the stationary phase (adsorption or ion-exchange chromatography) or the packing may be th

Thin-layer Chromatography, Shraiber in 1938. Meinhard and Hall in 1949 developed this notion of an ‘open column’, and in 1951 Kirchner, Miller, and Keller reported the separation of terpenes on a ‘chromatostrip’, prepared by coating a small glass strip with an adsorbent mixed with starch or plaster of Paris, which acte
