Measurements were carried out using the gas sensor array consisting of six TGS. Responses of this device to such alcohols as methanol, ethanol, propanol and butanol were investigated. Water vapour influenced sensor responses to each alcohol. On the basis of experimental results it was possible to establish the discriminative factor. It improved the results of recognition of alcohols in humid air. Methanol and ethanol were successfully recognised in 100% cases. The percentages of correct recognition of propanol and butanol were 85% and 95%, respectively.

Przeprowadzono pomiary za pomocą matrycy czujnikowej składającej się z sześciu czujników TGS. Przeanalizowano odpowiedzi matrycy na pary alkoholi: metanolu, etanolu, propanolu i butanolu w powietrzu. Odpowiedzi czujników na pary alkoholi zależą od wilgotności powietrza. Korzystając z tego, zaproponowano wzorce par alkoholi w matrycy czujników na podstawie wyników pomiarów par alkoholi w powietrzu wilgotnym. Wyróżnione wzorce umożliwiły poprawę wyników rozpoznawania alkoholi za pomocą matrycy czujników. Dzięki ich zastosowaniu uzyskano 100% skuteczność rozpoznawania metanolu i etanolu. Propanol i butanol były rozpoznawane odpowiednio w 85% i 95% przypadków.
