The Problem with PIDs (photoionization detectors) and …

20160104· 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 …
