Abstract The gas‐phase of two diesel fuels scented with perfume mixtures were examined with a FOX 4000 electronic nose (Alpha‐M.O.S., France) and a Smart Nose GA (LDZ Laboratory, Switzerland). The first system uses chemical gas sensors, the second a mass spectrometer. The data of both instruments were evaluated by principal component analysis (PCA) and linear discriminant analysis (LDA). The LDA results obtained allowed the detection of a much lower perfume concentration with the mass spectrometry data than with the chemical sensor data. Copyright © 2000 John Wiley & Sons, Ltd.
