Gas Chromatograph Gas Chromatography
Gas ChromatographyChromatography: Separate analytes in a mixturewith a resolution in the shortest amount oftime and detection of separated Chromatograph123456= Gas supplies usually have traps to remove anywater, oxygen, hydrocarbons or other contaminants from compressed gases Instruments can have multiple injectors,detectors or columns Injectors and detectors temperatures controlled The GC oven has a large fan and a vent door forrapid cooling/heating. Data collection /and integration system The analyte (GC) necessarily in gas between the mobile phase (carriergas) and the liquid stationary phase(predominant) inside capillary column or onparticles inside a packed column Some packed-column GC uses non-coatedsolid stationary phases; gas-solid adsorptionchromatographyAchieve separation by using suitable; columns with properstationary phase, diameter ofcolumn,stationary phase loading, , and columnlength.
Bonded – thermally stable. Mobile phase - carrier gas (GC), usually an ‘inert’gas, primarily pushes the material through the column. In LC; m.p. is a solvent, should be compatible with the analytes and influences the equilibration process in partitioning etc.
