What Is A VOC Detector And Why Do You Need One? | GDS Corp

2020-06-26· The most common detection technique used by VOC monitors designed for industrial safety is “photoionization”, and a sensor that uses photoionization is called a “Photoionization Detector”, or “PID” for short. These PID detectors depend on the fact that complex VOC compounds can be ionized by photons of ultraviolet light. Ionization is the process whereby a loosely-held electron is ...

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

2016-01-04· PIDs or photoionization detectors are also known as volatile organic compound (VOC) detectors. We love PIDs because they’re a great tool but people believe them without question way too often. Think of a PID as a very powerful UV lamp. When the energy from that lamp comes into contact with a gas molecule, it temporarily splits (ionizes) the gas molecule into pieces (ions). These ions …
