A sensory system on a mass spectrometric basis (MS-Sensor) has been developed in the course of this study. The implementation of the MS-Sensor has been carried out in face of all the currently well-known limitations and disadvantages of common multi-array chemosensory systems. The sensing principle is based on the injection of complex sample headspaces into a mass spectrometer, thus creating mass spectrometric patterns of the unresolved gaseous mixtures. The resulting mass spectra of the unresolved mixtures are treated with multivariate data analysis. By selecting a set of particular fragment ions, the user defines a sensor array used for sensor analysis. Individual fragment ions are equivalent to individual sensors, with their intensities being treated as sensor signals of solid state chemosensors.
