The prior edition was the first comprehensive reference work for GC/MS. The new edition likewise offers broad coverage, from sample preparation to the evaluation of MS-Data, including library searches. Fundamentals, techniques, and applications are described. Several new chapters like 'Automated Solvent Extraction (ASE)', 'Hyphenation with Isotope Ratio MS' and an accurate description of the topical TOF-technique have now been added. A large part of the book is devoted to numerous examples for GC/MS-applications in environmental, food, pharmaceutical and clinical analysis. These proven examples come from the daily practice of various laboratories. The book also features a glossary of almost 300 terms, now considerably extended, and a substance index that makes finding a specific application easier.
