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.

Taking CHARON PTR-TOF to the Sky

At the Frontier of Airborne Research aboard NASA’s Flying Laboratory

Using the opportunity provided by NASA’s Student Airborne Research Program (SARP) we gave wings to our newly developed CHARON aerosol inlet. In cooperation with the University of Oslo our team combined CHARON and a custom built PTR-TOF 4000 instrument.

“Business Class” for our airworthy CHARON PTR-TOF 4000, monitoring VOCs & aerosol in real-time.

Airworthiness requires withstanding of heavy G-forces, coping with pressure changes and most importantly being fail safe. Therefore unique modifications to CHARON have been made and thoroughly tested before getting airborne. (more…)

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:

CHARON Real-Time Aerosol Inlet System for PTR-TOFMS

Direct Sampling and Analysis of Atmospheric Particulate Organic Matter

An international team of researchers from the University of Innsbruck (Austria), the IRCELYON in Lyon (France) and the University of Oslo (Norway) recently studied the application of the new CHARON Particle Inlet to directly sample and analyze the chemical composition of atmospheric sub-µm particulate organic matter (POM) by PTR-TOFMS.

By conducting laboratory based measurements of pure aerosolized substances the team could demonstrate the quantitative response of CHARON PTR-TOFMS to a range of typical POM substances down to single-digit ng m-3 mass concentrations. This quantitative response combined with the low selectivity of PTR-MS led to a good agreement in the detection of total urban POM in comparison with other state-of-the-art aerosol instrumentation.  (more…)

CHARON PTR-ToF-MS: a new method for real-time measurement and molecular-level characterization of submicron particulate organic matter

Soon this powerful add-on will become available as an upgrade exclusively for selected IONICON PTR-TOF instruments. Expect nothing less than a revolution of existing methods for on-line and real-time characterization of organic particulate matter: measure aerosols directly with your IONICON PTR-TOFMS! (more…)

Food-grade CO2 analysis: new PTR-TOF 1000 ultra application

Real-time Quantification of Impurities in Food-Grade CO2 with PTR-MS

The modern food and beverage industry is not imaginable without food-grade carbon (CO2) dioxide. Its many uses include carbonation of beverages, and as packaging and cooling gas.

Pittcon 2017 poster: Real-time Quantification of Impurities in Food-Grade CO2 with PTR-MS.

In this study we investigate volatile organic impurities emerging from a food-grade certified (European standard E 290) carbon dioxide cylinder using a PTR-TOF 1000 ultra.

The PTR-TOF 1000 ultra is a compact PTR-TOFMS equipped with the ION-BOOSTER funnel technology. Its high sensitivity make the PTR-TOF 1000 ultra a perfect tool for applications where complex matrices have to be rapidly analyzed. One such example application is quality assurance in the food and flavor industry.
