Planar Chromatography Application in Analytical Toxicology

I. PLANAR CHROMATOGRAPHY

A. Recent Practice

Planar chromatography is a natural tool for analytical toxicology. This technique allows chemical analysis to be done on a surface in such manner that the analyst can observe and control the process to achieve the desired end. The goal of this analysis is to fully separate and identify an unknown chemical that caused a harmful (often fatal) effect, usually on a biological system or entity. The most sophisticated confirmation may be made by spectral analysis, or the simplest colorimetric detection may be made. On a preparative scale, isolation and full characterization may also be made.
