"We use our PTR-MS system, consisting of two compact PTR-MS and a calibration unit, to measure breakthrough curves of adsorption filters for various gases, including highly toxic substances. The tailored Ionicon dilution stages gives us the unique opportunity to measure in a very wide range from 5 ppb to 1000 ppm."
"IONICON PTR-MS allow fast and precise measurements of several key VOCs and are therefore very useful for our studies on VOCs sources from remote environments (first measurements in Antarctica) to rural (isoprene fluxes measurements in Provence) and urban atmosphere (one-year measurement in Paris atmosphere, tunnel experiment, and OH reactivity evaluation)."


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 […]

CHARON PTR-TOF and new technologies for increased PTR-TOF performance Our team was able to meet many of you at the ASMS meeting and our science presentations. Those of you who didn’t make it to the conference or our posters, are now able to pull a copy from our website. See what’s coming up and get […]
