Generally reverse phase is used. 3. Feed the data into the system or program the HPLC. Assign the number to the solvents when you are opting for gradient elution. Specify the flow rate. Regulate the pressure of the pump. 4. Analyse your sample. Add your sample in the injector system.

Gas chromatography is an analytical tool for the separation of compounds in complex mixtures based on the polarity of compounds. Separation is achieved only for com-pounds that are volatile or

How Gas Chromatography Works. First, a liquid sample is prepared. The sample is mixed with a solvent and is injected into the gas chromatograph. Typically the sample size is small -- in the microliters range. Although the sample starts out as a liquid, it is vaporized into the gas phase. An inert carrier gas is also flowing through the
