Photoionization detector - Wikipedia

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. PIDs produce instantaneous readings, operate continuously, and are ...

Accurately Measuring Volatile Organic Compounds (VOC’s ...

A VOC will be ionized and detected by the PID sensor if the energy it takes to break up the VOC molecules, or Ionization Poten-tial, is lower than the energy emitted by the UV lamp in the sensor. PID lamps are created containing a variety of gases including Krypton, Xenon, and Argon. Each gas emits a speci˛c photon energy when heated, which would ionize a di˜erent subset of VOC molecules.
