New Possibilities for 14C Measurements by Liquid Scintillation Counting

Liquid-Scintillation Counting of 14C-Labelled Animal Tissues

Developments of liquid-scintillation counting as a practical method for the assay of radioisotopes in biological samples followed work by Reynolds, Harrison & Salvini (1950) and Kailmann & Furst (1950). Reviews of progress and developments in liquid-scintillation counting have been given by Davidson & Fiegelson (1957) and Bell & Hayes (1958). Guinn (1958) and Stitch (1959) have reviewed the adv...

Cocktails for Liquid Scintillation Counting

It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....

Liquid Scintillation Counting

discussed, and he points out that merely because a disease is found to be familial in incidence does not mean it is hereditarily transmitted; leprosy, for instance, was long held to be a hereditary disease, and a law was actually proposed in the Norwegian Parliament forbidding the marriage of lepers for that reason. It was only with the discovery of the leprosy bacillus by Hansen that the true ...

Determination of accurate counting efficiency for liquid scintillation counting.

Liquid scintillation counting of (3H) and (14C) on solid supports: a warning.

Liquid scintillation counting of (3H) and (‘“C) -labeled compounds on solid supports is a common practice in biochemistry. Furlong has recently emphasized “local quenching” of tritium by filter paper, and has suggested that p’s of higher energy might also be anomalously absorbed if they penetrated under the surface of a filter paper support (1, 2). It is the purpose of this report to show that ...
