We investigated the effect of zeolite at the sample input of a gas-analysis
system (Electronic Nose) on recognition of volatile molecular mixtures. It is shown that
the NaX molecular sieves can remove ketone-type molecules from a gas sample more
efficiently than the NaA molecular sieves. A comparison of recognition of four different
perfumes, both with and without NaA zeolite at the inlet of a multisensor system, showed
that introduction of zeolite reduces responses of all sensors and does not improve
recognition
