In volatile organic compounds and olfaction analysis, electronic nose instruments have been established as reliable and rapid tools to assess the sample quality. To improve the Alpha M.O.S. analytical instruments-electronic nose -, an additional headspace sampling accessory has been developed and adapted to the product line : the Solid Phase Microextraction (SPME). To assess sample quality in complex headspace for olfaction applications, this technology provides significant benefits : a better sensitivity, an enhanced selectivity. This work shows the advantage of the SPME technique combined with the sensor array system (FOX4000) for the analysis of volatile compounds complete desorption of the compounds in the injector. excellent repeatability of the SPME in comparison with the other classic headspace techniques. higher selectivity with the SPME. The use of the SPME, combined with Alpha M.O.S. electronic noses, extends the potential of applications. Better selectivity and lower detection threshold can be obtained. The automation of the sampling process keeps the system easy to handle.
