What Gases Does a PID Detect?

PIDs are considered broad-band detectors because they will respond to almost any gas or vapor that has an ionization potential (IP) lower than the energy output of the UV lamp.

Common targets include:

• Aromatics: Benzene, toluene, xylene, styrene.
• Olefins (Alkenes): Butadiene, hexane, propylene.
• Halogenated hydrocarbons: Trichloroethylene (TCE), perchloroethylene.
• Oxygenated compounds: Alcohols, ketones, aldehydes, esters (e.g., acetone, ethanol, ethyl acetate).

• Amines and sulfur compounds: Mercaptans, hydrogen sulfide (at certain levels).

Note: PIDs do not detect common background gases like nitrogen, oxygen, carbon dioxide, carbon monoxide, or methane because their ionization potentials are too high for standard UV lamps to affect.
