| Abstract | |
Two e-nose setups formed by similar sensing units based on nanofibers and drop-cast films of poly(vinylidene fluoride) (PVDF) were compared. In both setups, the sensing units were formed by pristine PVDF and PVDF modified with conducting polymers. The e-noses were tested in a custom-made chamber with volatile organic compounds (VOCs) and ammonia, using dry nitrogen as a flow gas. Overall, both e-nose devices discriminate against almost all vapors, especially ammonia. The results suggest that the e-nose based on nanofibers can distinguish ethanol from isopropanol, which is not possible with the e-nose based on drop-cast films of the same materials. (AU) | |
