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 a real 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.

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…)

There’s suspense in the air – detected with IONICON PTR-TOFMS

Scientists analysed the air in cinemas and discovered that every movie leaves a characteristic pattern of VOCs

Thomas Klüpfel installs a tube into the ventilation system of a cinema for PTR-TOFMS monitoring.

Researchers at the Max Planck Institute for Chemistry and the Johannes Gutenberg University in Mainz, Germany investigated how the composition of the air changed when an audience watched movies from different genres such as comedies like “The Secret Life of Walter Mitty” and “Buddy”, or fantasy movies like “The Hobbit” and the science-fiction thriller “The Hunger Games”. The scientists determined how the audience reacted to individual movies on a scene-by-scene basis. Using their analyses incl. PTR-TOFMS data, they were also able to reconstruct which scenes were playing at the time. (more…)
