Excelitas Technologies Corp. Photoionization Detector Lamp PID Lamp

Excelitas offers a complete range of DC and RF-operated Photoionization Detector (PID) lamps with the highest intensity, spectral purity, and long life, making them ideal for detecting Volatile Organic Compounds (VOCs). Our decades of experience in lamp design and manufacturing are leveraged to ensure our customers benefit from the highest product quality and reliability. Our DC and RF excited PID lamps are available with a selection of gas fills and window materials to cater to the specific requirements of your VOC sensor project. Photoionization detector lamps are most commonly used in VOC gas detection. Gas chromatography (GC) and sample ionization for mass spectrometry are other areas of use. The PID technique uses a lamp with known photon energies in the vacuum ultraviolet (VUV) region. The lamp output is used to photo-ionize gaseous molecules with ionization potentials lower than the photon energy emitted. Typical photoionization detectors measure VOCs and other gases in concentrations ranging from the ppm to ppb level.
