Gas chromatography is used in many research labs, industrial labs (quality control), forensic (arson and drug analysis, toxicology, etc.), environmental labs (water, soil, air), and even in the popular TV culture (crime shows like NCIS (. Evidence. 1. Class characteristic—ink analysis, paper analysis, most handwriting analysis. 2. Individual characteristic--With document analysis, it is difficult to identify to an individual characteristic except with typewriter or printer specific marks.. 1.

Used solid adsorbent: activated charcoal. . . 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. Dr . Debalina. . Basu. Department of Microbiology. Surendranath. College. Paper Chromatography. Principle. What is Descending Paper Chromatography?. 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.. Get complete detail on IT Audit Fundamentals exam guide to crack ISACA IT Audit Fundamentals.
