Liquid Scintillation Counting Technique (X)

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 ...

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....

Determination of accurate counting efficiency for liquid scintillation counting.

Measurements of Strontium-90 in portuguese milk samples using liquid scintillation counting technique

The objective of this study is the implementation of a method combining extraction chromatography and liquid scintillation counting (LSC) technique to the determination of 90Sr in milk samples. The strontium separation is performed using the commercially available Sr-resin (Eichrom) and the beta counting is carried out using a liquid scintillation detector system (Tri-Carb 3170 TR/SL, Packard)....

Rapid method for homogenizing tissue samples for liquid scintillation counting.

EVALUATiON OF A new drug includes analysis of its tissue distribution. We have developed an improved method for solubilizing tissues that is not only rapid, but results in a homogeneous sample for counting. We had found that organs rich in connective tissue (heart, lung, skeletal muscle, urinary bladder, stomach, and intestinal wall) could not be completely disrupted by conventional techniques ...
