GC can be applied to the separation of any compound that is either naturally volatile (i.e., readily goes into the gas phase) or can be converted to a volatile derivative.. . Botanist. In 1906 Tswett used to chromatography to separate plant pigments. He called the new technique chromatography because the result of the analysis was 'written in color' along the length of the adsorbent column. By . Dr. . Amjad. M. T. Khan. Assistant Professor.

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.
