| Abstract: | Thermospray liquid chromatography-mass spectrometry has been applied in the solution of a number of problems of biological and biomedical interest. These include the analysis of phenazines from the Gram negative bacterium Pseudomonas aeruginosa, steroids released by rat adrenals and eicosanoids generated by human inflammatory cells. The application of the technique to leukotrienes in blood is discussed. Isotopic labelling prior to analysis, to facilitate identification and structure elucidation is outlined with reference to the steroids. |
