PROMISING the highest performance and lowest detection limits for the detection of volatile organic compounds (VOCs) using proton transfer reaction mass spectrometry, the PTR-QMS-500 series from Ionicon is a new generation of ultra-sensitive PTR-MS online mass spectrometers.
Ionicon's PTR-QMS 500 promises the highest sensitivity for VOC detection
Detection limits lower than 1pptv (part per trillion) are said to be possible with these quadrupole based systems, the successors to the PTR-MS range which Ionicon says are the world’s best-selling instruments of their type.
Chief among the improvements is the new Ionicon Ultra-Pure ion source, which the company says delivers unprecedented precursor ion intensity, enabling the PTR-QMS 500 to continuously quantify VOCs in the lowest possible concentrations.
In addition, the size and weight of the instruments has been reduced without affecting maintainability. A touchscreen display is now featured on all Ionicon instruments, and a new heating chamber layout gives easier access to the ion source.
