Photoionization detector (PID) is gas sensor that uses ultraviolet (UV) light detect volatile organic compounds (VOCs) in the air. Here is breakdown photoionization detector how it works Light source and ionization: PID uses specially designed ultraviolet lamp that emits high energy photons light to particles at specific wavelengths. These photons target VOC molecules in the […]
