Gasera launches disruptive multi-gas analyzer to protect life, health, and security GASERA ONE is a portable device for conducting ultra-sensitive, multi-gas analysis. Using its patented, cantilever-enhanced photoacoustic technology, Gasera Ltd. delivers a market-disruptive solution for climate change prevention, border security, and occupational safety improvement.

Gasera, a Finnish-based high-tech company, announces the launch of GASERA ONE, a new portable device for air quality and security measurement. GASERA ONE is based on cantilever-enhanced photoacoustic tech-nology. It utilizes several different infrared light source technologies, such as widely tunable quantum cascade lasers (QCLs). This enables countless application areas for reliable ppb-level trace gas monitoring.

GASERA ONE measures, for example, VOCs, inorganics, hydrocarbons, fluorocarbons, anesthetics, and corro-sives at very low concentrations.

“Our concept is unique, since it can monitor such a wide range of gases at a ground-breaking sensitivity level. Many chemicals can severely damage human health, even at low concentrations. Its high level of sensitivity to harmful gases combined with the stability of our patented technology gives GASERA ONE a true advantage for reliable multi-gas analysis,” says Gasera’s CEO, Ismo Kauppinen.

Detects greenhouse gases, illegal substances, and hazardous chemicals

The main application areas include climate change prevention, border security, and occupational safety. GAS-ERA ONE simultaneously measures, for example, methane, nitrous oxide, and ammonia emissions from animal agriculture, a growing concern in combatting climate change. A vast number of illegal substances related to ter-rorism or smuggling, including narcotics, explosives, and even human beings, can be monitored using GASERA ONE at border crossing points or airport security checkpoints

Real-time detection of hazardous chemicals present in, for example, cargo containers or indoor air can bring remarkable improvements for both living and occupational conditions. Currently, approximately 20–30% of test-ed cargo arriving at major destination ports is identified as containing multiple chemical compounds exceeding Occupational Exposure Limits (OEL).

GASERA ONE has huge market potential, according to Kauppinen.

“The market potential for a multi-gas analyzer like GASERA ONE is enormous thanks to the wide range of possible application areas. Our mission for the future is to miniaturize the technology into a hand-held ana-lyzer for personal air quality measurements that anyone can use,” says Kauppinen.

A significant advantage of the product is the intuitive interface, which is easy to use with a single knob or your smart device. Thanks to its photoacoustic detection scheme, GASERA ONE gives an exceptionally high level of stability with a re-calibration period ranging from several months up to several years, and thus it offers a low total cost of ownership.

Gasera is a Finnish high-tech company established in 2004 as a University of Turku spin-off company. Its activi-ties build on patented gas measurement technology. Gasera employs 32 persons. In 2015, the EU Horizon 2020 Framework Programme granted Gasera EUR 2.3 million for the development and commercialization of a portable device for detecting hidden drugs, explosives, and people as well as toxic substances in the indoor air of cargo containers. Gasera’s vision is to bring hand-held multi-gas analyzers with lab-grade performance to consumer markets in the future. For more information, visit www.gasera.fi.

Protecting life, health and security

GASERA ONE concept GASERA ONE is a photoacoustic multi-gas analyzer that serves a wide variety of research and industrial applications. It combines the best of both worlds in the detector and the light source sides. The unmatched performance of GASERA ONE is based on a photoacoustic infrared spectroscopy engine with a patented ultra-sensitive cantilever pressure sensor.

Many problems – one simple solutionGASERA ONE can be tailored to suit multiple applications by selecting optimal lasers and/or light sources. For even more complex measurement scenarios, several GASERA ONEs can be stacked and synchronized to provide an ultimate solution for your application.

Easy-to-use – one button operationGASERA ONE provides the user with a simple and intuitive interface with high resolution display and a single rotating knob. In addition, the user can control the GASERA ONE wirelessly with smartphone, tablet or other devices.
