Launch of new ultra-sensitive IONICON PTR-QMS 500 series

A new generation of ultra-sensitive PTR-MS online mass spectrometers for VOC analysis now complements the IONICON PTR-QMS series

We  present the new PTR-QMS-500 series to the analytical and laboratory market: highest performance and lowest detection limits (< 1 pptv) for VOCs detection and monitoring based on Proton Transfer Reaction – Mass Spectrometry. The PTR-QMS 500 series is the 4th generation of PTR-MS systems developed and commercialized by IONICON Analytik GmbH, Innsbruck Austria.

The High-Sensitivity PTR-QMS 500 and its sister instrument, the PTR-QMS 500 are the successors of the world’s bestselling PTR-QMS instrument series, the IONICON High-Sensitivity PTR-MS and Standard PTR-MS. This is the new flagship quadrupole-based PTR-MS series where created a new generation of instruments providing the highest sensitivity available in the PTR-MS market but also incorporating several new features and improvements we developed in response to the needs and feedback of our customers.


IONICON US, Inc. starts its operations in North America

Effective and fast local PTR-MS sales and support for US customers now directly available from IONICON US, Inc., New Jersey.

In March 2011 we founded IONICON US, Inc., a totally-owned subsidiary of Austrian-based IONICON Analytik GmbH. Our new US subsidiary takes over the marketing and after-sales-support for the United States and Canada. I am looking forward to the start-up of operations at IONICON US. This will improve the user experience as one of our most experienced PTR-MS experts is now residing in New Jersey and is available for inquiries, customer showcases and professional after-sales-service.


New Overview Article on IONICON PTR-MS and its Applications in “American Laboratory”

Technical Advances in Proton Transfer Reaction-Mass Spectrometry and New Fields of Application.

In 1998 IONICON was founded and we were able to sell the first commercial instrument. Since then, after years of dedicated research, passionate development and intensively working together with our partners and customers, we sold more than 200 units. Learn more on the recent advances of the PTR-MS technology, our products and their applications in an article with the title Technical Advances in Proton Transfer Reaction-Mass Spectrometry and New Fields of Application, published in American Laboratory (September 01, 2011) being available online.

Innsbrucker Forscher und PTR-MS waren Teil der NASA Mission DISCOVER-AQ

PTR-MS hilft dabei neue Erkenntnisse über die Schadstoffverteilung in der Atmosphäre zu gewinnen.

Armin Wisthaler und Tomas Mikoviny von der Universität Innsbruck sind das einzige ausländische Forscher-Team, das auf Einladung der NASA an 14 Messflügen mit ihrem PTR-MS Instrument teilgenommen hat.

Detaillierte Kenntnisse über die Verteilung und den Transport von Luftschadstoffen in der Atmosphäre können zuverlässig nur durch Messungen aus Luft gewonnen werden, weshalb die beiden Forscher im NASA Messflugzeug P-3B über dem Großraum Washington-Baltimore unterwegs waren. Mit ihrem Protonentausch-Reaktions Massenspektrometer (PTR-MS) wurden die Konzentration von verschiedenen Kohlenwasserstoffen ermittelt, die an der Bildung von Ozon und Feinstaub beteiligt sind. „Wir haben bereits vor drei Jahren mit dem PTR-MS an einer NASA-Kampagne sehr erfolgreich teilgenommen, weshalb man uns auch zu DISCOVER-AQ wieder eingeladen hat“, erzählt Wisthaler. „Da das Flugzeug etwa 100 Meter pro Sekunde zurücklegt, sind schnelle Messungen, wie sie das PTR-MS durchführen kann, unabdingbar“, ergänzt er. Während des Fluges wird über einen Einlass Luft eingesaugt und das PTR-MS ermittelt in Sekundenschnelle die Konzentration von Kohlenwasserstoffen.


First results of CERN’s CLOUD experiment now published in NATURE journal

PTR-MS technology made in Austria contributes to important results of the CLOUD experiments at CERN.

The CLOUD experiment has been designed to study the effect of cosmic rays on the formation of atmospheric aerosols – tiny liquid or solid particles suspended in the atmosphere – under controlled laboratory conditions. Atmospheric aerosols are thought to be responsible for a large fraction of the seeds that form cloud droplets.

The CLOUD results show that trace vapors assumed until now to account for aerosol formation in the lower atmosphere can explain only a tiny fraction of the observed atmospheric aerosol production. The results also show that ionization from cosmic rays significantly enhances aerosol formation. Precise measurements such as these are important in achieving a quantitative understanding of cloud formation, an important contribution to climate models.

The prestigious NATURE journal has now published first results from the CLOUD experiment, where two PTR-MS instruments from the Institute for Ion Physics and Applied Physics of the University of Innsbruck contributed to this cutting edge project. A quadrupole based PTR-MS was used to monitor trace concentrations of Ammonia and a PTR-TOF-MS system (based on time of flight technology) continuously scanned organic vapor concentrations in the CLOUD chamber.


IONICON at 6th Future Security, Security Research Conference

IONICON science manager, Dr. Philipp Sulzer will co-chair the session A3 Detection of hazardous Material and give a lecture.

Terrorism, organized crime and sabotage, but also natural disasters and technological accidents can cause serious damage and disruption with long-lasting consequences for economies and the quality of life.

The 6th Future Security, Security Research Conference will take place 5. -7. September 2011 in Berlin, Germany and has the aim to bring together the decision makers in politics, industry and finance with scientists working on leading edge and innovative concepts, sensors or systems for civil security.

Philipp Sulzer will chair the session Detection of Hazardous Material on Tuesday September 6 from 9:00 to 10:20 and give a lecture with the title: Detection and Identification of illicit and Hazardous Substances with Proton-Transfer-Reaction Mass Spectrometry (PTR-MS).

PTR-MS compared to SIFT-MS, APCI and MS-e-noses

A new review article in Trends in Analytical Chemistry discusses direct-injection mass spectrometry for VOC analysis.

F. Biasioli, C. Yeretzian, T. D. Märk, J. Dewulf and H. Van Langenhove wrote an interesting review with the title “Direct-injection mass spectrometry adds the time dimension to (B)VOC analysis” that was recently published in Trends in Analytical Chemistry 30 (7) (2011).

We at IONICON are often asked what actually the differences and in our case, the benefits of the PTR-MS technology compared to other, similar methods are. Not only a technical comparison is of interest but also feedback from studies in the field covering various applications is in high demand by people contacting us.

For me the advantages of PTR-MS are obvious and I also know which position our technology and products have in the market, but of course it is more credible if an article in a peer-reviewed journal has such a comparison as topic and gives the reader a chance to follow a well grounded debate.
The synopsis of this article with regards to PTR-MS and my conclusion, I would summarize as follows only mentioning the most intriguing arguments:
