Raytest – Renowned for Precision in Radiation Detection
Raytest's precision radioactivity-measuring instruments have earned a sound reputation for excellence and ease of use in chromatography, as well as many other fields such as quality control, nuclear medicine, environmental protection, and biological and medical research and development.
Many of raytest's instruments can be used with the GINA Star software for measurement, evaluation and control for HPLC and GC.

Radioactive HPLC Detection
Radioactive High Performance Liquid Chromatography (HPLC) detection – online measurement of radioactivity in HPLC eluates – has gained wide acceptance for the qualitative and quantitative analysis of radioisotopic biological samples, replacing fraction collection and discrete sample counting, and offering real-time results and high resolution. Detection of radioisotopic samples separated by liquid chromatography can be optimized using state-of-the-art liquid scintillation counting techniques in a flow scintillation analyser, (FSA), also known as a radioactive monitor or radioactive flow detector.

Radioactive TLC Detection
The major limitation to the use of thin-layer chromatography (TLC) is that a suitable method of detection must be available; however, this limitation is removed when the compounds of interest are radiolabelled. Early methods of quantifying the distribution of radioactivity whilst still maintaining good resolution were time-consuming or labour-intensive, or yielded low resolution results. However, detection instruments have greatly improved over the years.
