"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.[...]"
"We use IONICON Instruments for atmospheric trace gas measurements. In particular we explore the ability to measure real-time eddy covariance fluxes, which requires a time resolution of 10Hz. As such PTR-MS has been a very valuable tool for our research."


Wood-plastic composites – replacing plastics with wood   In the quest for new alternatives for crude oil based materials such as plastics, WPCs (Wood-plastic composites) seem to be suitable materials, used in buildings and in the automobiles production. WPC are natural fiber composites with properties of both plastic and wood. It is estimated that the production […]

IONICON autosampler for automated head-space analysis with PTR-MS The real-time capability of a PTR-MS gas analyzer is typically utilized to continuously monitor trace VOC concentrations – but not only. Some users appreciate the enormous speed of a PTR-MS to rapidly analyze discrete samples in seconds, where a manual sample provision can be the bottleneck. This […]
