GIS
Gas Interface System
The Ionplus Gas Interface System GIS is the most versatile gas handling system for ¹⁴C-AMS measurements of CO₂. Direct measurements of CO₂ 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 CO₂ 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 CO₂-producing device is possible through the integrated zeolite trap.
