The PTR-MS Technology and how PTR-MS works
Detailed theoretical background information about PTR-MS technology. Understand what determines the performance of our solutions.
Switchable Reagent Ions (SRI)
Discriminate isomers in real-time with the new "Switchable Ion" feature using H3O+, NO+ and O2+ as precursor ions with your PTR-MS.
PTR-MS Sensitivity and Detection Limits
PTR-MS is the benchmark for all online trace gas mass spectrometers and has detection limits in the upper ppqv-range / single-digit pptv-range. Discover why PTR-MS is the best solution for real-time trace gas analysis.
