This volume is one in a series designed for the individual chromatographer, providing guidance and advice on a wide range of chromatographic techniques with emphasis on important practical aspects of the subject. The measurement of chromatographic peaks is the focus of this volume. In particular, it describes and discusses the manual and electronic techniques use to make these measurements and how to use integrators. The aim is to help analysts get more data from their chromatograms and to help them understand how integrators work so that results are never accepted unquestioningly.
