Progress on Instrumental Analysis Methods for Malodorous Substances

The total concentration is important for the detection of malodorous substances.But what is more,the compositions and corresponding concentrations of malodorous substances are also necessary.With the development of analytical techniques for trace gas,more and more malodorous contaminants could be analyzed quantitatively.Due to a wide variety of species and properties,the analytical methods of malodorous substances are varied.This article is an overview on instrumental analysis methods for malodorous substances.The issues of sampling,pretreatment,and selection of analytical instruments are discussed according to the physical and chemical characteristics of different malodorous substances, and the analytical techniques and standards available are also summarized.
