Multidynamic measurement of small Neodymium (Nd+) ion signals on Faradays using Xact amplifiers with 1e11 Ω and 1e12 Ω (1T) resistors
Zenon Palacz, Davydd Wanless, Ian Turner & Tony Jones. Isotopx Ltd. UK Introduction Thermal Ionization Mass Spectrometry is an extremely sensitive detection technique. For Neodymium, measured as Nd+ , ion yields of 1 ion per 50 atoms loaded are typical for triple filament geometries on a Phoenix TIMS. This efficiency is of huge importance for…
