A new air-quality measuring instrument invented by Pat Arnott and Ian Arnold of the University of Nevada, Reno that is more economical, more portable and more accurate than older technologies has been licensed for commercial development by Droplet Measurement Technologies of Boulder, Colo.
Arnott, a physics professor in the University's College of Science, had perhaps lugged his heavy pieces of equipment one too many times through airports to faraway places to examine airborne particles. Now, his and Arnold's latest invention has reduced the laser-equipped air-monitoring equipment to suitcase size, while enhancing its measurement capabilities.
This latest, compact version of the photoacoustic particle measuring machine with its lasers, mirrors, flexible tubes, wires and relays is also cheaper and faster and should be an attractive alternative for users.
"This machine will be much more ubiquitous for measuring air quality, or more precisely, black carbon in the air, or a number of other uses," Arnott said. "Key component cost and instrument weight have dropped from $2,000 and 180 pounds to $40 and 20 pounds. This will make it more accessible to researchers, businesses and government agencies; and much easier when traveling around the world to gather data."
Over the past 12 years, Arnott, along with collaborators from the Desert Research Institute, have mapped air pollution on Los Angeles freeways, as well as in Mexico City, the rain forests of Brazil, Vancouver, B.C., and Big Bend National Park, to name a few locations. They have also worked 1,600 feet underground in an active Nevada gold mine to monitor air quality.
Arnott's invention is an improvement on earlier technology he developed with partners. Arnott, John Walker and Hans Moosmüller, all at the time with DRI, commercialized the first version of the instrument with Droplet Measurement Technologies in 2005.
The University of Nevada, Reno's Tech Transfer Office, worked out the deal with DMT to commercialize the technology.
"The new device is a smaller, less expensive photoacoustic instrument for measuring airborne particles related to air quality that makes it affordable for a broader range of uses and it promises to lead to much wider market adoption of photoacoustic technology," said Ryan Heck, director of the University's Tech Transfer Office. "Pat and DMT have worked together for years, and we were pleased to help facilitate a new product based on their collaboration."
Arnott and DMT have already built beta-versions of the device that are in use by researchers at the Lawrence Berkeley Labs and the Bay Area Air Quality District, at the Max Planck Institute for Chemistry in Europe and in locations in Mexico City. Droplet is working to produce many more that will be a fraction of the cost to users.
"We're pleased to have entered into the licensing agreement," John Lovett, CEO of Droplet said. "Pat is a leading scientist in applying photo-acoustic technology to aerosols and has partnered with DMT on developing research-grade scientific instruments for air quality assessment.
"Our new instrument, the Photoacoustic Extinctiometer —PAX, is a next generation monitoring tool to help scientists and air quality engineers accurately assess the optical properties of aerosols that are relevant for climate change and visibility. By measuring the aerosol in its natural state (photoacoustically), without requiring filter collection, the PAX improves measurement accuracy over older competing technologies."
Arnott and Arnold, an undergraduate student in Physics at the University when he assisted Arnott with instrument development, are also working on developing a truly miniature device that may find use as an on-board sensor for real-time black carbon air pollution emission control.
The University of Nevada, Reno's Tech Transfer Office develops license agreements with business and industry for technologies produced and patented at the University. They have more than 30 technologies available for licensing in a variety of commercialization categories including renewable energy, life sciences, physical sciences, environmental sciences and the medical field.
Nevada's land-grant university founded in 1874, the University of Nevada, Reno has an enrollment of more than 17,000 students. The University is home to the state's medical school and one of the country's largest study-abroad programs, and offers outreach and education programs in all Nevada counties.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
