Materials for Field Ionization Gas Sensors

It was found that these sensors can detect many gases, such as air. He, Ar, and gas mixtures, without gas separation (Modi et al. 2003). We need to note that ionization gas sensors such as photo-ionization detectors (PID), flame-ionization detectors (FID), or electron-capture detectors (ECD) are not suitable for direct application to gas mixtures. These detectors work in conjunction with a gas chromatography setup that separates the mixture into distinct bands that can then be qnalitatively and quantitatively analyzed (Modi et al. 2003). In addition, FID has poor selectivity and requires bulky and hazardous [Pg.409]
