SIFT-MS (selected ion flow tube mass spectrometry) is used to construct libraries for emissions from pig and broiler farming activities. Libraries are based on full mass scans in m/z range 15 to 250 using HO+, NO+ and O2 precursor ions. The so-called ‘Yule coefficient’, which represents one algebraic number as singular descriptor for similarity between samples, is chosen as the best tool to identify similarities between a given sample and library data. The proposed methodology, which is simple and straightforward, is successfully applied on data from different experimental sampling campaigns. From an engineering point of view, it is considered to be a promising technique to evaluate whether a sample corresponds to one of the catalogued library data sets.
