We are the world’s leading producer of real-time 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 PTR-TOF 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 monitoring as well as instruments for COVID-19 detection in breath. We manufacture modular time-of-flight mass spectrometers for academic research projects & as OEM. We also offer analytical services and are an active contributor to numerous international scientific research and training projects.
