Analytical instruments and monitoring solutions

We are developing individual analytical instruments and industrial monitoring solutions according to our customers' needs for more than a decade. Benefit from our scientific and engineering expertise!


Proton Transfer Reaction - Mass Spectrometry
PTR-MS (Proton Transfer Reaction – Mass Spectrometry) is the benchmark method for simultaneous real-time monitoring of volatile (organic) compounds (VOCs) without sample preparation in very low concentrations. We're the market-leading PTR-MS company.
Selective Reagent Ionization - Mass Spectrometry
SRI-MS is a new technology where the user can select from different reagent ions for chemical ionization direct injection mass spectrometry, only available from IONICON. Our expertise as the world's leading PTR-MS company lead to the development of new ionization technologies currently including H3O+, O2+, NO+, Kr+ or Xe+ as selective reagent ions.
H3O+ and NO+, O2+ / Kr+, Xe+ as precursor ions.
Quantify more volatile compounds than ever in real-time with IONICON PTR-MS and SRI-MS technology, using the SRI/SRI+ features, and take advantage of single-digit pptv-level detection limits, only available with IONICON real-time trace gas analyzers.


"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."
"We use IONICON Instruments for the measurement of VOCs in mainstream smoke and the exhaled breath of smokers. The PTR-MS is a valuable tool for our research as it allows us to conduct continuous real-time measurements of compounds of interest in a rapidly changing, complex mixture on a puff-by-puff basis."
