We are the world’s leading producer of real-time PTR-TOF trace gas & organic particle analyzers based on Proton Transfer Reaction – Mass Spectrometry (PTR-MS) technology, with a market-leading detection limit < 0.1 pptv for VOCs.

Considered as academic but also industrial “gold standard”, our instruments are used in environmental research, air quality monitoring networks, atmospheric chemistry, engine emissions testing, food & flavor science and medical breath analysis.

We also supply industrial VOC monitoring systems such as the AMC-Monitor for cleanroom and FOUP analysis in the semiconductor industry, BTEX air pollution tracking as well as fenceline emissions monitoring for production sites.

We manufacture modular time-of-flight mass spectrometers for academic research projects & as OEM.
