A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm).The photoionization detector is an efficient and inexpensive detector for many gas and vapor analytes.A PID may produce instantaneous readings and operate continuously. These hand-held, battery-operated detectors are widely used in military, industrial, and confined working facilities for safety.he first commercial application of photoionization detection was in 1973 as a hand-held detector for the purpose of detecting leaks of volatile organic compounds (VOC's), specifically vinyl chloride monomer (VCM), at a chemical manufacturing facility.
