The VCS-203 system is a hardware and software package for testing radiochemical purity with thin layer chromatography and for the execution of basic gamma spectrometry. The system is available in two configurations, for low energy or high energy isotopes analysis. For PET analysis (high energy) is available a module for the half-life measurement on a peak on the chromatography strip. This feature enables the determination of radiochemical purity and the confirmation of radionuclide identity in one automatic procedure. In the high energy configuration is also possible to perform the system suitability test, which uses a two-spot Cesium-137 test strip.
