By Lothar Matter
In accordance with a few conferences held by means of the German Chemical Society, offers sensible suggestion for analysts and technicians who're no longer now or ever intend to be specialists at the approach yet use it since it works. Covers employing the foundations of chromatography to capillary fuel chromatography, deciding upon residues and contaminants, settling on polycyclic fragrant hydrocarbons in nutrients, and the mass-spectrometer as a detector within the procedure. Translated from released by way of VCH Verlagsgesellschaft in 1994.

Although testosterone acetate and nortestosterone propionate coelute under the chosen conditions, in the case of a positive finding a distinction between these two compounds would readily be possible on the basis of their differing mass spectra. The middle chromatogram shows a positive hormone detection in veal. 3 Applications of GC/MS to the Analysis of Residues and Contaminants in Foods 41 ~~ I r Hormones in Veal Testosterone acetate 1 Nortestosterone propionate 2 Norethisteroneacetate 3 Testosterone propionate 4 Estradiol valerate 5 Estradiol dipropionate 6 Medroxyprogesterone 7 acetate Megestrol acetate 8 Testosterone isocapronate 9 Testosterone oenanthate 10 Estradiol benzoate 11 Testosterone benzoate 12 Testosterone cypionate 13 Nortestosterone decanoate 14 Testosterone decanoate 15 Estradiol undecylate 16 Cholesterol CH Fig.
