摘　　要：本文简要介绍PID原理特点,并较全面、系统地介绍PID在空气、水及土壤中环境污染物的分析应用。In recent years, PID has been used for analyzing pollutants in air, water and soil samples to detect hydrocarbons, hylogenated hydrocarbons, and salfur-, phosnhorus-, arsonic-and nitrogen-contained compounds at ppb and ppm levels. Unsaturated hydrocarbons, such as alkene and aromatic hydrocarbons can also be detected selectively. The linear dynamic range is up to 10~7. The PID has the advantage of non-destructive detection and is widely used as GC detector. PID can also be used in series with other detectors (FID, ECD, etc) , and by using their normalized relative response factor, the components in complex mixtures can be identified qualitatively according to their chemical classes.
