Liquid chromatography–mass spectrometry (LC–MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography - MS systems are … See more The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were … See more Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio (m/z) of charged particles (ions). Although there are many different kinds of mass spectrometers, all of them make use of electric or magnetic fields to manipulate the … See more The coupling of MS with LC systems is attractive because liquid chromatography can separate delicate and complex natural mixtures, which chemical composition needs to be well established (e.g., biological fluids, environmental samples, and drugs). Further, … See more • Thurman, E. M.; Ferrer, Imma (2003). Liquid chromatography/mass spectrometry, MS/MS and time of flight MS: analysis of … See more Liquid chromatography is a method of physical separation in which the components of a liquid mixture are distributed between two immiscible phases, i.e., stationary and mobile. The practice of LC can be divided into five categories, i.e., See more The interface between a liquid phase technique (HPLC) with a continuously flowing eluate, and a gas phase technique carried out in a vacuum was difficult for a long time. The advent of electrospray ionization changed this. Currently, the most common LC-MS … See more • Gas chromatography–mass spectrometry • Capillary electrophoresis–mass spectrometry • Ion-mobility spectrometry–mass spectrometry See more WebGas chromatography separates according to vapor pressure and not boiling point. For example, if you have a non-polar column, but a mixture of alcohols and hydrocarbons, the higher boiling point alcohols will elite much sooner than the corresponding hydrocarbon of the same boiling point.
