"We require high sensitivity and fast response times in order to push the boundaries of Oxygenated Volatile Organic Compound (OVOC) research in both air and seawater. The PTR-MS meets these requirements and is also extremely adaptable, enabling us to carry out our novel science not only in the laboratory, but also at sea."
"Measurements of VOCs are extremely rare in the tropical region of Asia. In India a variety of sources such as anthropogenic, biomass burning, biogenic and photochemical sources contribute to the budget of VOCs. In tropics, the fast response time measurements of VOCs are required to understand the rapid photochemical formation of ozone and secondary organic aerosols. In India, the PTR-TOF-MS based measurement is particularly crucial to understand the tropical photochemistry. The high time and mass resolved measurements of VOCs using PTR-TOF-MS will be important to estimate the emissions flux from terrestrial vegetation and surrounding oceanic regions of India.[...]"
"Brilliant combination of in obtaining sophisticated data and simplicity in operation and maintenance."


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. Airworthiness requires withstanding of heavy G-forces, […]

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 […]
