Liquid chromatography–mass spectrometry (LC-MS or LCMS) is the term for an analytical chemistry technique. Scientists use LC-MS to separate, isolate, and evaluate components of a compound. The duties of people in LC-MS jobs involve using instruments to perform analysis in a laboratory setting. Researchers, R&D scientists, and laboratory technicians use LC-MS techniques to test products in the food, cosmetic, and pharmaceutical industries. Scientists with chemical, agricultural, and biomedical qualifications also use this technique. After collecting data from the LC-MS equipment, your responsibilities include using your scientific skills to interpret your findings and, in some cases, apply the results to product development.
