Radiolabeled materials are often analyzed by chromatography. The original application of liquid scintillation counting to chromatographic techniques was to collect and count discrete fractions. This manner of counting is extremely laborious, and resolution is limited…

Complex radioactive samples are often fractionated on polyacrylamide gels. Analysis of radiolabeled samples in electrophoretic gels follow the same pattern as that on TLC plates. The gel is analyzed as a whole for radioactive bands,…
