Ruggedized and Airworthy PTR-TOF 4000

Custom-built by IONICON engineers for the University of Montana

One of the special skills we are known for is to custom-build PTR-TOFMS and ioniTOF systems for research and industrial applications. Our engineering team is eager to work out special solutions and by now we have a solid track record for more than two dozen tailor-made analytical instruments that are fully customized.

Each one is unique and purpose-built to withstand G-forces, shocks, varying pressure levels and temperatures that you and I wouldn’t like to experience. Often also size and weight matters and our team has to make the instrument fit into spaces where a normal analyzer is too large or heavy. (more…)

This very successful event organized by the University of Innsbruck every couple of years, attracted the community from all over the world for one week full of science and networking. Latest developments were showcased, results discussed and a bright outlook given for IONICON’s real-time trace gas analyzers. (more…)

Launching our new ultra-sensitive PTR-QiTOF trace VOC analyzer

Welcome to the future: 25x more sensitive, we proudly present our new flagship PTR-TOFMS instrument: the IONICON PTR-QiTOF.

PTR_QiTOF_webFeaturing a Quadrupole ion guide (Qi), the PTR-QiTOF achieves a performance, no other commercial PTR-TOFMS system has ever been able to demonstrate before.

Expect up to 25x more sensitivity, one order of magnitude lower detection limit and 20% higher mass resolution than the world’s current bestselling and up to now also best-performing PTR-TOFMS instrument – our PTR-TOF 8000.

Vacancy from the PTR-MS Community

Full-time experienced PTR-MS technician/scientist at the University of Antwerp

Technicians or scientists with experience in PTR-MS are high in demand!
Below you’ll find an interesting opening at our colleagues at the University of Antwerp. The PLECO research group has got two of IONICON’s  proton transfer reaction mass spectrometers (PTR-QMS and PTR-TOF-MS). PLECO’s PTR-TOF 8000 can be used to measure not only BVOC concentrations, but also BVOC fluxes in the field.

Find all details of this vacancy here: Full-time experienced PTR-MS technician/scientist to join the PLECO research group, University of Antwerp, Belgium.

IONICON PTR-TOF-MS helps providing new insights and a SCIENCE paper

Extremely large range of VOCs are a challenge to current emission, air quality, and global climate models.

J.-H. Park et al. were relying on an IONICON PTR-TOF 8000 instrument to study fluxes of an unprecedented number of volatile organic compounds (VOCs) simultaneously. Their results, “Active Atmosphere-Ecosystem Exchange of the Vast Majority of Detected Volatile Organic Compounds“, have recently been published in the prestigious SCIENCE Magazine. Using traditional measurement techniques, monitoring of VOCs was limited to a few selected compounds, the authors explain, whereas PTR-TOFMS technology reveals 186 organic ions with a net deposition, and 494 that have bidirectional flux.

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:

Ultra-sensitive and fast detection of BVOC emissions with IONICON PTR-TOF

Detection of Plant Volatiles after Leaf Wounding and Darkening by Proton Transfer Reaction ‘‘Time-of-Flight’’ Mass Spectrometry (PTR-TOF)

A new study published yesterday, where IONICON PTR-TOFMS was used to detect biogenic volatile organic compounds (BVOCs) induced by leaf wounding and darkening, shows the huge potential of PTR-MS for monitoring and quantification of  fast processes in our environment. Leaf wounding reactions where BVOCs are emitted occur very fast and therefore a method is necessary that can capture the BVOC profiles in seconds. A very high time resolution and sensitivity in combination with the high mass resolving power of a time of flight makes the PTR-TOFMS technology an ideal tool for such applications. PTR-MS can detect most of the common VOCs in real-time, in very low concentrations and without complicated sample preparation as our online mass spectrometers directly inject the sample gas and provide results without delay.

The study is an outcome of the Marie Curie Industry-Academia Partnership and Pathways (IAPP) project 218065 ‘‘PTR-TOF’’ funded by theEuropean Commission within the Seventh Framework Programme (FP7 – People), where IONICON is one of the partners.
