METHODS OF SOURCE ATTRIBUTION FOR CHEMICAL COMPOUNDS

Methods of determining the source of an unknown sample are disclosed. Mass spectra from possible sources are obtained using two-dimensional gas chromatography coupled with time-of-flight mass spectrometry. That data is processed to obtain a dataset. A random forest algorithm is used to classify the...

Zusammenfassung:Methods of determining the source of an unknown sample are disclosed. Mass spectra from possible sources are obtained using two-dimensional gas chromatography coupled with time-of-flight mass spectrometry. That data is processed to obtain a dataset. A random forest algorithm is used to classify the dataset and create a classifier that distinguishes between the possible sources.
