Odor Detecting Experiment and Result Analysis Based on Photoionization Detector

Abstract:

Odor pollution means a distinctive gas that is offensively unpleasant and harmful for the living conditions, not only disturbing social activities but also being harm for human. For the character of odor pollution, a kind of odor detecting system based on photoionization detector (PID) has been developed. The capillary column has been used as separate device and the PID as detector. From stability experiment of PID sensor, the standard deviation of system is 5.88×10^-3, relative standard deviation is 0.14%. Furthermore, the experimental results of the sample calibration and stability illustrated that by using ethyl alcohol, xylene and butane, system lineaity is 99.99%, 99.98%, 99.98% respectively and the limit of detection is 0.8ppm, 1ppm and 0.6ppm respectively. PID has good stability and the experimental system has better reliability and repeatability.
