Liquid chromatograph coupled with a Q-TOF mass spectrometer (6520).

Chromatography is a powerful analytical tool for separating compounds from a given matrix, whether for the identification, confirmation or quantification of analytes. The service has several chromatographs available. Depending on the nature of the analytes to be analysed, liquid or gas chromatographs and different detection systems—ultraviolet, fluorescence, and mass spectrometry—are used. The mass detector is considered one of the most versatile and is mainly used to identify and confirm compounds. It is a highly selective detector, as it can detect the characteristic mass of a compound and, by selecting that mass, can selectively detect the compound of interest in a complex matrix, thereby resolving interference issues within the sample matrix.
