Food and Environmental Analysis by Capillary Gas by Lothar Matter

By Lothar Matter

According to a couple of conferences held by way of the German Chemical Society, offers functional recommendation for analysts and technicians who're no longer now or ever intend to be specialists at the procedure yet use it since it works. Covers utilizing the foundations of chromatography to capillary gasoline chromatography, settling on residues and contaminants, deciding upon polycyclic fragrant hydrocarbons in meals, and the mass-spectrometer as a detector within the process. Translated from released through VCH Verlagsgesellschaft in 1994.

3 Applications of GCiMS to the Analysis of Residues and Contaminants in Foods 53 C Figure 2-17: Gas chromatographic separation of a mixture of Clophene A30/A60 (top), selected individual isomers of PCB (middlc), and Ugilcc 141 (bottom) on a DB-5 capillary. 54 2 GC/MS Determination of Residues and Contaminants Above all, mention should be made of the PCB congener with Ballschmiter number 153, for which a limiting value is stated in German maximum pollutant level legislation. The joint presence of TCBT and PCB in a food sample would thus inevitably lead to erroneous results if PCB 153 is determined by GC/ECD.
