Basic Protocols in Enology and Winemaking -

. .

Résumé :
This volume details methods using classical apparatus and mechanisms to study enology and winemaking. Chapters guide readers through protocols on titration, distillation, spectrophotometry, advanced methods applying High-Performance Liquid Chromatography with Mass Spectrometry (HPLC-MSn), Gas Chromatography coupled with Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR). Authoritative and cutting-edge, Basic Protocols in Enology and Winemaking aims to be a useful and practical guide to new researchers and experts looking to expand their knowledge. ...
