A gamma‐ray detector for capillary zone electrophoresis and its use in the analysis of some radiopharmaceuticals

Abstract
The construction and evaluation of a gamma-ray detector for capillary zone electrophoresis is described. The detector was shown to have a linear response from the limit of detection 10 to 500 Bqcm−3 corresponding to 5.1 x 10−17 to 2.55 x 10−15 gcm−3 43Tc99m. The application of the detector for the analysis of some radiopharmaceuticals is presented.
