Did you know that Heraeus PID lamps have been used in the measurement of air quality at the London airport?

02.05.2016

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.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...

New design tool automatically creates nanostructure 3D-print templates for user-given colors
Scientists present work at prestigious SIGGRAPH conference

Most of the objects we see are colored by pigments, but using pigments has disadvantages: such colors can fade, industrial pigments are often toxic, and...

Im Focus: Unraveling the nature of 'whistlers' from space in the lab

A new study sheds light on how ultralow frequency radio waves and plasmas interact

Scientists at the University of California, Los Angeles present new research on a curious cosmic phenomenon known as "whistlers" -- very low frequency packets...

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
