The key to ultra-high sensitivities is the novel patent-protected 3D tripole reaction chamber where long reaction times are combined with precise control of the ion chemistry via electric fields. With the dual-stage core sampling inlet system, which enables analyte transfer with virtually no wall interactions, organics ranging from volatile to even extremely low volatility (ELVOC) can be measured, even at ambient sample inlet temperature. In addition, the PTR3 has the unique ability to detect and quantify RO2 radicals. Since the invention of the PTR3 principle by Breitenlechner et al. at the University of Innsbruck, Austria, the instrument was revised and complemented with the latest IONICON technologies. Now outstanding sensitivities of more than 50000 cps/ppbv are achieved e.g. for ketones. Another innovation is the Time-of-Flight mass spectrometer itself. Ions are analyzed with the novel high-resolution ioniTOF 10K, achieving mass resolving powers of typically 10000 to 15000 m
