Radioactive tracer-paper chromatography techniques

Abstract: The uses and potentialities of combined radiochemical and paper chromatography techniques are discussed. The principle of the methods is to associate one or more radioactive isotopes with one or more substances separated on a paper chromatogram. The labelled substances can then be located and estimated by scanning the paper radiometrically. A simple device for doing this automatically and its use in quantitative work is described.

“…acetone containing 5 % stage technique described (Winteringham, 1952b). Labelled compounds were located and determined on the paper chromatograms by the methods described elsewhere (Winteringham, Harrison & Bridges, 1952). A sensitive 4hr scanning technique was used for very low 14C-activities (Harrison & Winteringham, 1955).…”

“…The simple two-stage chromatographic technique (normal-phase as opposed to reversed-phase) proved to be the more useful technique for measuring the pyrethroid/ non-pyrethroid ratio in the tissue extracts. In this technique (Winteringham, 1952 b) the chromatogram is first developed for a few minutes with acid light petroleum (boiling range 40-60°), dried and then redeveloped for a longer period with amimoniacal light petroleum (boiling range 40}60').…”

“…(b) Radiometric method. The 14C-labelled compounds were located and assayed on the unidimensional chromatograms by a method in which the paper chromatogram is passed automatically beneath a thin end-window Geiger-Muller tube and the radioactivity is automatically plotted (Winteringham, Harrison & Bridges, 1952). Each zone of radioactivity on the strip is represented by a peak on the graph and the area enclosed by the peak is proportional to the amount of 14C in the zone which it represents.…”

“…Some constituents have been tentatively identified by co-chromatography. The amounts of 32p in fractions II, III and IV, measured by radiometric scanning (Winteringham, Harrison & Bridges, 1952), have been expressed as percentages of the total 32P in the three fractions. Where DDT was used 100 ,Ag.…”
