GIS

Gas Interface System

The Ionplus Gas Interface System GIS is the most versatile gas handling system for ¹⁴C-AMS measurements of CO. Direct measurements of CO are performed on ultra-small samples of 3 to 100 μg carbon with the GIS + MICADAS/MILEA coupling. Gas measurements are the ideal solution not only for small samples but also for all lower precision samples in screening and high throughput studies. Sample CO is mixed with helium and the mixture is continuously fed into the ion source of MICADAS/MILEA.

All functionalities of the instrument are software-controlled and fully automated for gas measurements without user interaction for 8 to 40 samples. Moreover, the coupling of virtually any CO-producing device is possible through the integrated zeolite trap.
