WebMass spectrometry (MS) has the capability to separate organic molecules according to their molecular mass and permits their detection and quantitation with extremely high sensitivity. High performance liquid chromatography (HPLC) facilitates the rapid, quantitative separation of compounds from each other and from the other constituents of complex Flow cytometry (FC) is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one … See more The first impedance-based flow cytometry device, using the Coulter principle, was disclosed in U.S. Patent 2,656,508, issued in 1953, to Wallace H.
