Air pollution such as ozone, nitrogen dioxide, volatile organic compounds (VOCs) and fine particulates - mostly from vehicular emissions - puts a strain on the environment and affects people’s health, which could result in reduced life expectancy.
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.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
