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 ...

PHOTOIONIZATION DETECTION (PID) TECHNOLOGY

PID lamps can be created with a number of gasses, each of which has different photon energy. TSI’s PID probes use Krypton gas, with photon energy of eV. While the intensity of PID lamps may change over time, or from lamp to lamp, affecting the absolute VOC measurement, PID sensors with a given lamp type will have the same photon energy.

The Problem with PIDs (photoionization detectors) and VOC ...

Jan 04, 2016· 2. Humidity is a problem. Humidity is a huge problem with some PIDs. Most PIDs and their users are blind to RH effects: Water vapour scatters and absorbs photons, reducing the PID output. This is also called ‘quenching.’. With high RH, you may find current leakage along the sensor walls, resulting in higher than actual readings.

Detecting VOCs with PID how it works

Having recently shared our video on pellistors and how they work, we thought it would make sense to also post our video about PID (photoionisation detection). This is the technology of choice for monitoring exposure to toxic levels of another group of important gases – volatile organic compounds (VOCs). The sensor includes electrodes and a […]

Understanding PID Detectors Advantages and Disadvantages

Sep 30, 2019· PID Detectors are commonly used to monitor VOC’s (Volatile Organic Compounds). Many gases and vapours fall under the VOC banner and IGD’s PID’s can monitor for over 300 Gas species. This makes a PID an ideal first responder for VOC leaks even though the PID cannot directly determine the gas type detected.
