Boost your research with holistic airborne chemicals analysis

Chemicals are fundamental in our daily lives, yet certain compounds pose threats to both human health and environment. To identify these potentially harmful substances among the myriad of compounds that surround us, ultra-sensitive and selective devices are needed.
 
We provide easy to use end-to-end solutions for air analysis with low detection limits and high selectivity. By partnering with leading universities and research institutes, we support scientific endeavors to expand the frontiers of fundamental science,  address environmental challenges and develop effective environmental policies.

Ultra-sensitive & selective, yet versatile!

The core of our technology lies in the ability to analyze airborne chemical compounds with high sensitivity and selectivity, bypassing traditional chromatographic techniques. We achieve high sensitivity by using chemical ionization at atmospheric pressure and injecting only reagent ions into the sample flow, avoiding the dilution of air samples. Unlike the Proton Transfer Reactor, our method uses soft ionization, where reagent ions form adducts with a sample gas, preventing fragmentation of the target molecules and ensuring high selectivity.
The versatility of our technology is greatly enhanced by the ability to switch between multiple reagent ions and polarities. With all sources switched off, MION2 can detect ambient ions. The switching can be as rapid as one second, enabling seamless analysis of a wide range of compounds without the need to change the setup, therefore, saving time. We call our technology the Multi-scheme chemical ionization inlet or MION2, and it can be easily integrated with OrbitrapTM and TOF-based (Tofwerk/Aerodyne) mass spectrometers.
