Abstract: Chemometric method such as cluster and principal component analyses applied for alkanes C6-C10 detection in the air. To increase piezosensor selectivity to analytes L-apiezon is applied as active modifier. It is shown that processing of piezosensor signals to analytes with cluster and principal component analyses allows to refer (to identify) substance to the appropriate alkane (hexane, heptane, octane, nonane, decane).


Keywords: piezosensors, alkanes, chemometrcis, principal component analysis, cluster
