Ionicon's PTR-TOFMS series, which includes the Ionicon PTR-TOF 8000 and 2000, moves online mass spectrometry for trace VOC analysis one step ahead.
The new PTR-TOFMS series includes the Ionicon PTR-TOF 8000 and the Ionicon PTR-TOF 2000.
Both instruments combine Proton Transfer Reaction (PTR) technology, which is ultra-sensitive to VOCs (single-digit pptv-range), with the speed and resolution of time-of-flight mass spectrometry.
The flagship of this series is the Ionicon PTR-TOF 8000, providing a resolution of up to 8000, resolving isobaric compounds, and a low detection limit of <10pptv.
The Ionicon PTR-TOF 2000 focuses on sensitivity and speed, reaching a limit of detection below 5pptv and high ion count rates.
It has a mass resolution of up to 2000.
The PTR-TOFMS and the PTR-QMS series (based on quadrupole MS) can be equipped with Switchable Reagent Ions (PTR+SRI-MS), where instead of the single precursor ion (H3O+) used so far in PTR-MS systems, NO+ and O2+ can be used to chemically ionise trace constituents in gas samples.
This allows isomeric VOC compounds to be separated and instantaneously quantified and also allows more substances to be detected.
