Did you know that Heraeus PID lamps have been used in the measurement of air quality at the London airport?
In a research project with the University of Cambridge, UK in and around London Heathrow airport a sensor network with 50 stations has been installed measuring the air pollution caused by road and air traffic around Heathrow airport.
For this purpose the small battery-powered instruments are lamppost-mounted, which contain a number of sensors that measure six gases, volatile organic compounds (VOCs) and airborne particulates. Heraeus Noblelight supplied PID lamps, which have been used for the detection in these sensors.
If you would like to know, how air analysis and emission protection with PID lamps works, read more on our website or contact us.
PID lamp (Photoionisation detector lamp)
PID lamp (Photoionisation detector lamp) PID lamp is most commonly used in VOC gas detection, in gas chromatography (GC) and sample ionisation for mass spectrometry.
The PID technique uses a lamp with known photon energies in the vacuum ultraviolet (VUV) region.
The output from the lamp is used to photoionise gaseous molecules with ionisation potentials lower than the photon energy emitted. Typical photoionisation 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.
