The Evolution from SIFT-MS to PTR-MS

From SIFT to ultimate performance PTR-TOF trace gas analyzers

The success story of PTR-TOFMS has its roots in the so-called “Flowing Afterglow Technique”, introduced in the 1960s. From this starting point continuous research and innovations by various experts, who wanted to eliminate instrumental drawbacks and shortcomings, have led to different technological milestones, among them SIFT-MS.

But innovation didn’t stop there and technological breakthroughs resulted in the development of PTR-MS, ultimately PTR-TOFMS as the current established “gold standard” for direct and extremely sensitive trace gas analysis.

Read our new whitepaper on the evolution from SIFT to PTR-TOF and all the benefits that are now available to you, beyond SIFT-MS.

All abstracts from the 8th International PTR-MS Conference are now online

In February 2019, the must-attend event for all PTR-MS users took place, attracting more than 100 participants from 18 nations. There’s a short review if you would like to know more.

Have you ever wondered what this huge number of IONICON instrument users achieves with their instrument, what they investigate, which complex processes they capture or industrial VOC monitoring challenge their solve with our instruments?

New IONICON Extended Volatility Range (EVR) PTR-MS

Ultra-Fast Time Response Even for IVOCs & SVOCs

Real-Time Ultra-Sensitive trace VOC analyzers from IONICON are known for their response times in fractions of a second and hence are often used to follow rapidly changing processes and VOC signals. However, some substances are known to show a slower instrumental response because of unwanted surface interactions. These substances are either highly polar or have a reduced volatility and are typically classified as „sticky“ compounds.

IONICON’s new EVR PTR-MS: ultra-fast response times for IVOCs & SVOCs

With IONICON’s new Extended Volatility Range (EVR) setup we minimize unwanted surface interactions and still preserve all the advantages of our fully pressure controlled inlet system. This extends our sub-second response from VOCs to a wide range of compounds in the intermediate-volatility range (IVOCs, e.g. 2-tridecanone and vanillin) and even reduces the response of semi-volatile species (SVOC) like cis-pinonic acid to single-digit seconds.

The 8th International PTR-MS Conference, Innsbruck, Austria – a review

Must-attend science forum attracted over 100 conferees from 18 nations

At the beginning of February 2019, the International PTR-MS Conference was held for the 8th time. Ever since the first International PTR-MS Conference in 2003, organized by the Institute of Ion Physics of the University of Innsbruck and sponsored by IONICON, the event became a fixed point in the scientific agenda of many of our international peers.

Talks at the 8th International PTR-MS Conference took place in a historic venue of the University of Innsbruck

Since then the conference evolved, attracting more and more participants filling larger venues. If at the very beginning technology enthusiasts and early-adopters were gathering to exchange and network on their experiences with the first IONICON Quadrupole-PTR-MS instruments, the meeting soon became the PTR-MS event for all IONICON instrument users. The program comprised a selection of parallel sessions covering the very broad field of applications that modern PTR-TOF instruments are successfully used in. (more…)

PTR-MS now with Patented Ion-Chemistry Quality and TRU-E/N

The proprietary TRU-E/N™ method for utmost quantification accuracy

Founded by the inventors of Proton-Transfer-Reaction – Mass Spectrometry more than 20 years ago, IONICON has always been renowned for absolutely precise control of the ion chemistry during chemical ionization.

For IONICON this fact is still true even after the introduction of Radio Frequency (RF) components for focusing and transferring the ions from the reaction region into the mass analyzer.

Several manufacturers of CIMS instruments are trying to boost the sensitivities to the high spheres in which IONICON’s PTR-MS instruments perform. However, this comes at an extremely high cost: control over the ion-chemistry is lost. Undefined fragmentation of analytes renders a comparison of results with values published in the ample PTR-MS literature and, most importantly, accurate quantification impossible. As the reduced electric field strength (E/N) in the reaction region cannot be calculated any more as soon as RF devices are implemented, no E/N values can be stated upon publishing of measurements*, which seriously limits the reproducibility of results.

PTR-MS is not PTR-MS?!

IONICON-grade PTR-MS Quality: Important Ion Chemistry Dimensions

You’ve got used to expecting an IONICON-grade instrument when you see the abbreviation “PTR-MS“? After all, more than 350 IONICON PTR-MS instruments yielded hundreds of high-impact papers and allowed gaining insights in various science domains. But, what determines a real IONICON PTR-MS and how does it compare to other CIMS technologies that sometimes are also claimed to be “PTR-MS”?

Watch our webinar and learn more about the 4 quality dimensions that determine genuine PTR-MS, a technology only available from IONICON:
