Photoionization Detectors

RC Systems’ photoionization detector (or PID detector) systems are engineered to detect a variety of organic compounds. These vapor and gas detectors provide effective, reliable performance in a broad range of applications.
An RC Systems PID detector is comprised of an ultraviolet lamp that emits photons that are absorbed by the compound in an ionization chamber. Photoionization occurs when an atom/molecule absorbs light from energy, which in sufficient levels causes and electron to leave, creating a positive ion. Ions produced during this process are collected on electrodes, and the current this generates provides a measure of the analyzed substance.
Because only a small fraction of the analyte molecules are actually ionized, this detection method is nondestructive, which allows it to be used in conjunction with another detector to confirm analytical results.
Our SenSmart 6500 photoionization detector and SenSmart 3500 photoionization detector options utilize cutting-edge technology to ensure accurate results in even the most challenging environments.
