Summary:Odours of new cars are important today for the consumers’ comfort. Due to the interior trim parts’ manufacturing process and to their petrochemical compounds based, many rubbers and foams used in automotive materials result in a “new car odour” mostly enjoyed but sometimes felt as unpleasant by customers. The use of olfactory sensory panels, especially trained to describe odours, is only one way of addressing that issue. Although they offer interesting characterisation methods, olfactory sensory panels may also have some drawbacks. The odours of several PVC skins were described by human assessors and the corresponding volatile organic compounds were also characterised by a commercially available Electronic Nose technique, based on QMB sensors, whereas their identification was carried out by GC/MS analysis. Finally, a confrontation of the three types of obtained data was performed and showed the existence of correlation as well as the interest of gas sensors device for automotive industry.
