Abstract

Electronic nose devices are of increasing interest for the quality control of beverage and food processing. Optical gas sensors that require low electrical power are in great need for such devices. Magnesium 5, 10, 15, 20-tetraphenylporphyrin thin film sensors have been fabricated by spin coating onto glass substrates for detecting specific alcoholic volatile organic compounds (VOCs). Responses of the films to various alcohols were monitored by UV/Vis spectroscopy using a homemade measurement setup, which employs a LabVIEW program to control the measuring process.
