PPT-GAS CHROMATOGRAPHY Is a technique used for separation of volatile substances, or substances

A sample containing the materials to be separated is injected into the gas chromatograph Gas Chromatography A mobile phase carrier gas moves through a column that contains a wall coated or granular solid coated stationary phase .

Descending paper chromatography is an analytical technique in which the mobile phase moves downward through the stationary phase. In other words, in this method, the development of the paper occurs due to the movement of the solvent downwards on the paper. Therefore, the solvent reservoir should be at the top of the paper. In this process, the movement of the solvent is governed by gravity as well as capillary action.. . . CHROMATOGRAPHIC TECHNIQUES. CONTENTS. Introduction to chromatography. History. Principles.
