|Title:||Electrospray ionization mass spectrometry fingerprinting of perfumes: rapid classification and counterfeit detection|
|Abstract:||A fast procedure to classify perfumes and identify counterfeit samples is described. Dilution of a few mu L of the sample in a 1:1 methanol/water solution is followed by detection of its major polar components via direct infusion electrospray ionization mass spectrometry (ESI-MS) in the positive ion mode. As proof-of-principle cases, three famous brands of perfumes were used. The ESI(+)-MS fingerprints of authentic samples were very characteristic, showing distinctive sets of polar markers for each sample. Principal component analysis (PCA) placed samples of the three perfume brands in well-defined groups. Counterfeit samples were also clearly detected owing to contrasting ESI-MS fingerprints, with PCA placing these samples far away from the authentic samples.
