Chapter 6 Photoionization Detectors
73 Chapter 6 Photoionization DetectorsChapter 6 PhotoionizationDetectorsThe Photoionization detector (PID) utilizes ultra-violet light to ionize gas molecules, and is com-monly employed in the detection of volatile or-ganic compounds (VOCs). This technique originallyfound use in bench top laboratory instruments, butits complexity limited its use elsewhere. The heart ofthe Photoionization detector is an ultraviolet source,which is essentially a lamp. Early versions of this lampused electrodes inside the lamp similar to those usedin the early days of the vacuum tube and were quitecostly to lamps used today do not contain electrodesand are both less costly and have a longer life expect-ancy.
