Photoionization Detector (PID) Lamp

Product Details Ordering Information Download Materials Related video Application Cases

The lamps used in PID technology possess specific photon energies in the vacuum ultraviolet (VUV) region. These lamps emit photons with energies sufficient to photoionize gaseous molecules whose ionization potentials are lower than the energy of the emitted photons. Typical photoionization detectors can measure volatile organic compounds (VOCs) and other gases at concentrations ranging from parts per million (ppm) to parts per billion (ppb).

Excelitas offers a comprehensive range of PID lamps, which feature exceptionally high intensity, spectral purity, and service life. Both DC- and RF-excited lamps are available in a variety of fill gases and glass materials to suit customer needs. In addition to PID lamps, we also provide power supplies.
Customers can also benefit from our design expertise. The Esselida technical team works closely with OEM manufacturers to design and manufacture products that meet customers’ specific size and performance requirements.
