Qtof is a mass spectrometry technique for detecting and identifying molecules of interest by measuring their monoisotopic mass. The Qtof technique makes it possible to precisely measure the monoisotopic mass of an ion and to deduce its gross formula. The Qtof spectrometers allow an analysis after ionization. This technique is used in practically all scientific fields: physics, astrophysics, chemistry in the gas phase, organic chemistry, dosages, biology, medicine …
