This volume discusses the latest analytical approaches used to sample defined molecular populations of metabolites via functional group derivatization, specialized chromatographic methods, and ionization techniques. Chapters cover key methods for sample introductions to the ion source, including direct flow, gas chromatography, liquid chromatography, and capillary electrophoresis. Chapters also explore non-targeted and targeted analyses, as well as the emerging field of metallomics. In the Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory. Cutting-edge and authoritative, Metabolomics is a valuable resource for students, researchers, practicing physicians and veterinarians, and administrators involved in the funding of research.
