IONICON have introduced their new generation PTR-TOF for quantification of volatile organic compounds (VOC), which is optimised for the detection of their oxidation products typically, present in the parts-per-quadrillion (ppq) range. The key to ultra-high sensitivities is the novel patented 3D tripole reaction chamber where long reaction times are combined with precise control of the ion chemistry via electric fields. A dual-stage core sampling inlet system, which enables analyte transfer with virtually no wall interactions, allows organics ranging from volatile to even extremely low volatility (ELVOC) to be measured, even at ambient sample inlet temperature. In addition, the PTR3 has the unique ability to detect and quantify RO2 radicals.

The latest instrument can achieve sensitivities of more than 50,000 cps/ppbv, e.g. for ketones. Ions are analysed with the novel high-resolution ioniTOF 10K, achieving mass resolving powers of typically 10,000–15,000 mm.
