a Regulatory View of the Importance of Chiral Discrimination,It is timely to review whether or not this is acceptable for two reasons: (1) there are now many well substantiated cases in which one isomer differs markedly in biological potency from the other and (2) advances in analytical techniques now permit the separate analysis of individual isomers.athlete’s-foot 发表于 2025-3-28 22:57:50

A Diode Laser Polarimetric High-Performance Liquid Chromatography Detector and Applications to Enanty in enzyme and free radical reactions are reviewed. Polarimetric detection with chiral chromatography of complex reaction mixtures has allowed identification of enantiomers, and with achiral chromatography of near racemates has given enantiomeric purities to 0.1%.FLIP 发表于 2025-3-29 15:21:35

J. W. Bridgesn verstehen zu können, war man stets auf das mitgegebene Schema angewiesen. Was dieses nicht zur Stellen, so konnte man aus den Bezeichnungen in der Regel nicht klug warden und mußte versuchen, so gut es ging, durchzukommen und nötigenfalls durch Probieren die richtige Schaltung herauszufinden.

Ulrich Taddaynt concepts Computer-aided methods provide today the possibility to handle, process, analyse, and retrieve large information volumes. Both, remote and close-range sensing, collect extreme quantities of data, but with different focus. Therefore, different processing strategies need to be developed to案发地点 发表于 2025-3-30 06:35:09
