Manual radioactivity Thin-Layer Chromatograph (TLC Analyzer) Most efficient and Highly sensitive detector for β-emitting nuclides The single trace radioactivity thin-layer chromatography detector is using a linear analyzer detector, which is sensitive over the entire chromatogram trace from the start to the front. β-emitting nuclides can be detected very efficiently. Manγ-radiation-emitting nuclides are emitting β-radiation as well. The pure γ-emitting nuclides can be detected also because they produce Compton electrons.
