This paper reviews the use of chromatography in the identification of malodour in laundry. Two approaches are described: the first involves the use of the traditional approach of gas chromatography mass spectrometry while the second approach uses a new approach based on multi-capillary column gas chromatography ion mobility spectrometry (MCC-GC-IMS). Examples of GC-MS data representative of the volatile compounds associated with the inside of a washing machine are shown. MCC-GC-IMS has the advantages of extreme sensitivity for volatile compounds as well as the ability to detect nitrogen and sulphur containing molecules. Finally, selected examples of the application of chromatography for the analysis of malodour are presented.
