Are you limited in sample size?

We understand that one of the major challenges in Geosciences is the analysis of small ion beams. Especially in studies that focus on isotope compositions of scarce materials (dust in ice cores, inclusions in diamonds, components of extraterrestrial material), or materials that have ultra-low concentration of the isotopes of interest (Hf in depleted peridotite, Re and Os in silicate rocks), but also in studies that aim to resolve isotopic variability on a small spatial scale (growth zones in minerals, teeth or hairs). Ultimately, the analytical precision of such studies is limited by the detection system of your mass spectrometer.

Thermo Fisher Scientific™ has developed a new design of amplifiers equipped with 10¹³ Ω Amplifier Technology, a revolutionary new resistor design guarantees fast response times and extremely low noise/signal characteristics. Experience 4-5 times better internal precision for small signals.
