Title: MOS–MOSFET gas sensors array measurements versus sensory and chemical characterisation of VOC’s emissions from car seat foams
Abstract: The present paper describes and compares three methods to analyse volatile compounds emitted by seven car seat foam samples: "electronic nose" with metal oxide semiconductor (MOS) and metal oxide semiconductor field effect transistors (MOSFET), ATD/GC/MS and sensory analysis. Principal component analysis (PCA) and generalised procrustes analysis (GPA) were used to investigate the discrimination between foam samples obtained separately by the three methods. Multiple factorial analysis (MFA) was applied to explore the relationships between "electronic nose" measurements and sensory assessments, which were discussed according to the identified volatile compounds. The established relationships highlighted the relevance of the "electronic nose" system to partly transcribe the olfactory information given by human panel. However, it brought a lower quantity of information than sensory analysis and an interesting correlation with sensory attributes and chemical compounds, but not as high as we could expect. Consequently, further work needs to be done to improve the correlation.
