When performing chromatography separation, it is essential to determine the precise point when a substance is eluted from the column or cartridge to achieve optimal fractionation.
A chromatography detector is a device used to detect the presence of individual substances as they elute from the column or cartridge. The detector converts a change in effluent levels into an electric signal which is recorded by a data system.
In preparative liquid chromatography, the detectors used must accommodate high flow rates and high sample concentrations associated with the process.
