"At Wageningen UR we see many research applications for the IONICON PTR-QiTOF. It’s easy use, sensitivity, accuracy and on line detection without the need of prior treatments makes it a high potential instrument for all kinds of diagnostic and quality oriented research, going from environmental issues, to food and to health biomarkers."
"We use IONICON PTR-MS and PTR-TOFMS instruments for real-time measurements of a broad array of VOCs in the atmosphere, including ecosystem and aircraft scale flux measurements, direct emissions from plants and microbial cultures, controlled laboratory oxidation studies of VOC reactions and secondary aerosol formation, and field studies of atmospheric chemistry and air pollution. The rapid response and low detection limits made possible by these instruments are critical to our scientific investigations."
"Our IONICON PTR-MS offers us the unique possibility to follow dynamic processes of VOCs in many aspects relating to food/food packaging and their physiological impact. This not only greatly complements our classical gas chromatography-based chemical analyses but also opens up new fields of investigation previously not accessible with these techniques."


Crucial application benefits from fast switching NH4+ ionization The proprietary and IONICON exclusive method of producing NH4+ solely from H2O vapor and N2 in the established hollow cathode ion source, without the need of any ammonia (PCT application submitted) has many advantages. Today we would like to introduce a promising application field where NH4+ is the […]

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 […]
