"IONICON's instruments are manufactured in top quality having a superior performance in sensitivity and detection limit"
"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.[...]"


Real-time VOC monitoring in FOUP, fab and the clean-room environment Airborne Molecular Contamination (AMC) is more and more taking center stage in today’s semiconductor manufacturing processes. In the past the focus was on filtering particles from the ambient air in the clean-room to reduce their negative impact on production yield. Using  expensive air filtration equipment and transport […]

INTRANEF – More analytical performance for agroindustrial applications Fondazione Edmund Mach (FEM) and IONICON are funding a PhD program in Physics at the University of Milan on the improvement of the analytical performance of PTR-MS in agroindustrial applications. The project is called “INTRANEF” for INcreasing ThRoughput and ANalytical Efficency of direct injection mass spectrometry for […]
