Abstract: An aerosol-generating article is provided, including an aerosol-generating substrate including: a homogenised plant material including at least 2.5 percent by weight of eucalyptus particles on a dry weight basis, an aerosol former, a binder, at least 0.04 mg of eucalyptol per gram of the substrate, on a dry weight basis, at least 0.2 mg of eucalyptin per gram of the substrate, on a dry weight basis, and at least 0.2 mg of 8-desmethyleucalyptin per gram of the substrate, on a dry weight basis. An aerosol-generating substrate, an aerosol-generating system, an aerosol produced upon heating of an aerosol-generating substrate, and a method of making an aerosol-generating substrate, are also provided.

Abstract: The invention relates to a method for analysing mass spectral data obtained from a sample in GC×GC (2-dimensional) mass spectrometry, comprising: (a) comparing mass spectral data of an analyte with mass spectral data of candidate compounds of known structure in a data library; (b) identifying a plurality of candidate compounds from the library based on similarities of mass spectral data; (c) predicting, for each candidate compound, a value of at least one analytical property using a quantitative model based on a plurality of molecular descriptors; and (d) calculating a match score for each candidate compound based on the value predicted in step (c) and a measured value of the analytical property for the analyte.
