New PTR-TOF 6000 X2 2019 Edition: More Performance – Reliable Results

Up to 3x increased sensitivity, a better LoD and 10% higher resolution

The IONICON PTR-TOF success story continues also in 2019 and starts with a performance upgrade for our PTR-TOF series. Continuous investments in R&D lead to a series of improvements of our hexapole Ion-Guide technology as well as the implementation of new RF-electronics catering to the high-performance ion-funnel and ion-guide set-up which we use at the PTR-TOF 6000 X2 (more…)

PTR-MS now with Patented Ion-Chemistry Quality and TRU-E/N

The proprietary TRU-E/N™ method for utmost quantification accuracy

Founded by the inventors of Proton-Transfer-Reaction – Mass Spectrometry more than 20 years ago, IONICON has always been renowned for absolutely precise control of the ion chemistry during chemical ionization.

ION-BOOSTER funnel and hexapole ION-GUIDE with TRU-E/N

For IONICON this fact is still true even after the introduction of Radio Frequency (RF) components for focusing and transferring the ions from the reaction region into the mass analyzer.

Several manufacturers of CIMS instruments are trying to boost the sensitivities to the high spheres in which IONICON’s PTR-MS instruments perform. However, this comes at an extremely high cost: control over the ion-chemistry is lost. Undefined fragmentation of analytes renders a comparison of results with values published in the ample PTR-MS literature and, most importantly, accurate quantification impossible. As the reduced electric field strength (E/N) in the reaction region cannot be calculated any more as soon as RF devices are implemented, no E/N values can be stated upon publishing of measurements*, which seriously limits the reproducibility of results.
