"The Ionicon PTR-MS offers us the excellent sensitivity and time resolution that we need for making virtual disjunct eddy covariance flux measurements of biogenic VOCs from forests to the atmosphere. In addition, the excellent service offered by Ionicon allows us to explore innovative uses of the instrument. For example, with their help we are now planning to measure landscape scale fluxes by mounting the PTR-MS on a small airplane."
"The PTR-MS instrument provide us with unique opportunities to investigate dynamic mass transfer processes at low concentrations for a relatively complex chemical composition. We have obtained very useful results related to e.g. emissions of odorous VOC from livestock production and biological air filtration of VOC."
"We use the PTR-MS instrument for both in vitro and in vivo measurements. It constitues an very useful tool to characterize the dynamics of aroma release and to better understand what are the main parameters influencing aroma release, taking product properties and individual physiology into account. It can constitute a first step in better understanding the dynamics of perception."

A novel proprietary method of NH4+ production for IONICON customers In PTR-TOF-MS traditionally H3O+ reagent ions produced from H2O vapor are used. NH4+ reagent ions have been mentioned in literature as being particularly beneficial because of higher sensitivity (less fragmentation) and higher selectivity (higher proton affinity). However, so far toxic and corrosive ammonia was needed […]
