An apparatus for centrifugal acceleration of paper chromatography

The design and manipulation of an apparatus for centrifugal acceleration of paper chromatography has been described. The main novel features consists of using filter paper strips instead of circular sheets and a constant flow solvent reservoir enclosed in the chromatography tank. Our arrangement is particularly suited for the quantitative analysis of materials labelled with radioactive isotopes of short half-lives and examples are given of the separation of some 82 Br- and 131 I-labelled substances. Advantages of the above method over circular paper chromatography are discussed.
