Why is an IONICON PTR-MS very well suited for your measurement tasks?
During the past two decades, the continued development of IONICON PTRMS systems has led to a steady advancement of our research capabilities resulting in important scientific discoveries as well as providing a large share of the biosphere-atmosphere VOC exchange measurements we have used as the basis for developing VOC emission models for air quality and climate models. In addition to the outstanding performance of their instruments, the excellent support and collaborative environment at IONICON have been critical to the success of our research program.
