Maurer, Meyer, Helfer, Weber: LC-HR-MS & MS Library of Drugs, Poisons, and Their Metabolites

Author: Hans H. Maurer, Markus Meyer, Andreas G. Helfer, Armin A. Weber

Developed by toxicologist Hans H. Maurer and his team, the Maurer/Meyer/Helfer/Weber LC-HR-MS/MS Library of Drugs, Poisons, and Their Metabolites consists of spectra for parent drugs or poisons, and their metabolites or artifacts, in various compound classification groups. This metabolite-based library helps minimize the risk of false negative LC-MS results. Learn more.
