Today, I would like to describe my favorite chromatographic books: from one I bought even before I (really) knew what chromatography is to one which has chapter with my name on it.
In liquid chromatography liquid mobile phase flows through the column with stationary phase. The main principle of separation remains the same.
The gas chromatography is special type of chromatography, where the mobile phase is gas, such as helium or nitrogen. The stationary phase is usually solid support covered with liquid layer.
Chromatography is analytical chemistry method which is used (and useful) for the separation of complex mixtures of chemical compounds. The main mechanism of the separation is repeatable distribution of the tested compound in between two different phases.
