Leak detectors identify, analyze, and measure any gases or fluids either entering or escaping an enclosed space or pressurized system. Leak detectors search for the source of a leak, how fast the substance may be coming in or going out and evaluating if the rate of entry or escape is increasing or decreasing. Most leak detectors measure the presence of helium gas and have vacuum technology already built into their construction.
Most leak detectors, like those in the Leybold product range, use a 180° mass spec, capable of bonding ions around a magnetic field. Leak detectors, in general, are fine-tuned to detect the presence of helium. Particles become ionized in the vacuum and accelerated with added voltage, separating them within the magnetic field and turning the ions into an electric current.
