The products of a chromatography depend on which method is applied. When applying a gas chromatography the mobile phase is gaseous, while the stationary phase is solid or viscous liquid. The products here are then gases and the separated molecules are then either bound to the solid or liquid phase. When applying a liquid chromatography the mobile phase is liquid and the stationary phase is solid, leading to liquid and solid end products. | |||
