内容説明
This Second Edition of the classic handbook details how to set up an HPLC system that capitalizes on the latest innovations. It covers new techniques in high-temperature, micro-flow, and ultra-fast chromatography, the linking of an HPLC to a mass spectrometer, and more. Complete appendices and supplementary material online, this guide has everything chromatographers need to know to confidently separate, identify, purify, and quantify compounds.
