In this work a system based on an array of five quartz microbalances (QMBs) coated with different metalloporphyrins has been proposed for measuring the Breath Alcohol Concentration (BrAC). Four of these sensors were functionalized with widely selective coatings and one with a metalloporphyrins modified in order to enhanced the sensitivity to alcohols. The results obtained for the BrAC estimation show that the system performances, in terms of accuracy, are absolutely adequate for the legal scopes of breath alcohol measurement.

Abstract
In this work a system based on an array of five quartz microbalances (QMBs) coated with different metalloporphyrins has been proposed for measuring the Breath Alcohol Concentration (BrAC). Four of these sensors were functionalized with widely selective coatings and one with a metalloporphyrins modified in order to enhanced the sensitivity to alcohols. The results obtained for the BrAC estimation show that the system performances, in terms of accuracy, are absolutely adequate for the legal scopes of breath alcohol measurement.File in questo prodotto:
