The PID technique uses a lamp with known photon energies in the vacuum ultraviolet (VUV) region.
The output from the lamp is used to photoionized gaseous molecules with ionization potentials lower than the photon energy emitted. Typical photoionization detectors measure volatile organic compounds (VOCs) and other gases in concentrations from the ppm to ppb level.
Heraeus offers a complete range of PID lamps with the highest quality in terms of intensity, spectral purity and long life. Both DC and RF excited lamps are available with a variety of gas fills and window materials. The right power supplies are also provided.
Customers can also benefit from our design expertise, as the Heraeus Technical Team works closely with OEMs to design and build products to meet their specific dimensional and performance requirements.
