Liquid Chromatography

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 popular in chemical analysis because the individual capabilities of each technique are enhanced synergistically Detectors for Liquid Chromatography Edited by Edward S Yeung Written by an expert in the field this comprehensive guide explains the basic principles behind detector response instrumentation and selected applications Early chapters cover absorption detectors for high performance liquid chromatography FTIR detection indirect absorbance detectors fluorometric detection and

In gas chromatography the mobile phase is a gas that is moved through the column while the stationary phase is a liquid film that coats the column filling (in packed columns) or the column wall (in capillary columns) Hence the correct name for gas chromatography is Gas Liquid Chromatography abbreviated GLC

Question: B) High Performance Liquid Chromatography Is Known For Wide Selection Of Mobile Phase And Stationary Phase As Well As Its Separation Power - State The Three Advantages Of HPLC IL Explain When Gradient Elution Is Best Used (3 + 2 Marks)

Chromatography is a method using mixed substances that depends on the speed at which they move through special media or chemical substances It consists of a stationary phase (a solid) and a mobile phase (a liquid or a gas) The mobile phase flows through the stationary phase Chromatography is much used in biochemistry and analytical chemistry

Chromatography is actually a way of separating out a mixture of chemicals which are in gas or liquid form by letting them creep slowly past another substance which is typically a liquid or solid So with the ink and paper trick for example we have a liquid (the ink) dissolved in water or another solvent creeping over the surface of a solid (the paper)
