• Sommario/riassunto: This is the first comprehensive reference work for GC/MS now in its second edition.It offers broad coverage, from sample preparation to the evaluation of MS-Data, including library searches. Fundamentals, techniques, and applications are described.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 terms and a substance index that helps the reader to find information for his particul
