High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture … Ver mais The sample mixture to be separated and analyzed is introduced, in a discrete small volume (typically microliters), into the stream of mobile phase percolating through the column. The components of the sample move … Ver mais A separation in which the mobile phase composition remains constant throughout the procedure is termed isocratic (meaning constant composition). (The example of these the … Ver mais Manufacturing HPLC has many applications in both laboratory and clinical science. It is a common technique … Ver mais Prior to HPLC scientists used standard liquid chromatographic techniques. Liquid chromatographic systems were largely inefficient due to the … Ver mais Partition chromatography Partition chromatography was one of the first kinds of chromatography that chemists developed. The partition coefficient principle … Ver mais Theoretical HPLC separations have theoretical parameters and equations to describe the separation of components into signal peaks when detected by instrumentation such as by a UV detector or a mass spectrometer.
