The difference between PID and FID detection technology

Differences between PID and FID:

Photo-ionization detectors (abbreviated as PID) and flame ionization detectors (abbreviated as FID) are detectors with good sensitivity to low concentrations of gases and organic vapors, and optimized configurations allow detection of a wide range of gases and organic vapors. Both technologies are capable of detecting concentrations down to the ppm level, but they utilize different detection methods. Each detection technology has its strengths and weaknesses, and the most appropriate detection technology should be used for the particular application. Overall, PIDs are compact, lightweight, and easy to use, making them very portable.
