A chemical sensing system that uses a new type of sensor film and digital signal processing of sensor dynamic responses is described. This system consists of quartz crystal microbalances coated with plasma polymer films. The sensor dynamic responses include information about the target gases, and linear filters can extract the dynamic parameters even when the gas concentrations change. An application to a fire alarm system is described based on the proposed method. This system can discriminate between the gases from burning polyvinyl chloride (PVC) cables and circuit boards.
