The two most common lamps used in Photo Ionization Detectors (PIDs) are 10.6 eV and 11.7 eV lamps. The 11.7 eV lamp measures the broadest range of compounds while the 10.6 eV lamp is more selective. To allow higher energy light to pass through, 11.7 lamps are manufactured with a cylindrical window (the flat surface…
