GAS LIQUID CHROMATOGRAPHY Principles Partition of molecules between gas (mobile phase) and liquid (stationary phase)
GAS LIQUID CHROMATOGRAPHY Principles Partition of molecules between gas (mobile phase) and liquid (stationary phase)
Most Common Stationary Phases 1. Separation of mixture of polar compounds Carbowax 20M (polyethylene glycol) 2. Separation of mixtures of non-polar compounds OV101 or SE-30 (polymer of methylsilicone) 3. Methylester of fatty acids DEGS (diethylene glycol succinate)
