Nd and Hf Isotope Measurements Using a Double Focusing Multicollector ICP-MS
Stefan Weyer (1) and Johannes B. Schwieters (2)
1) Goethe-Universität, Frankfurt, Germany, 2) Thermo Fisher Scientific, Bremen, Germany
AN30013
Goal: This report describes the short- and long-term performance of the NEPTUNE. The short-term reproducibility is demonstrated by the measurement of an Nd standard solution over 3.5 hrs. The long-term reproducibility of Hf isotope composition measurements is measured over a 9 month period.

EA-IRMS: Tracing the geographical origin of coffee using isotope fingerprints
Maryam Weigt, Christopher Brodie and Oliver Kracht
Thermo Fisher Scientific, Bremen, Germany
AN30418
Goal: In this application note we show hydrogen and oxygen stable isotope measurements on roasted coffee samples measured with the Thermo Scientific™ EA IsoLink™ IRMS System. We were able to trace the origin of coffee beans based on unique trends observed from their isotopic fingerprints.

The power of stable isotope analysis
HJ Jost
Thermo Fisher Scientific, Bremen, Germany
Spectroscopy Online
Goal: Identifying the origin of CO2 in various samples is a major challenge for environmental scientists, regulators and the industry. Different emission sources create CO2 with different isotopic signatures. The Delta Ray Isotope Ratio Infrared Specometer is a powerful instrument for field CO2 monitoring and analysis.
