Based on a number of meetings held by the German Chemical Society, provides practical advice for analysts and technicians who are not now or ever intend to be experts on the technique but use it because it works. Covers applying the rules of chromatography to capillary gas chromatography, determining residues and contaminants, determining polycyclic aromatic hydrocarbons in food, and the mass-spectrometer as a detector in the technique. Translated from published by VCH Verlagsgesellschaft in 1994.
