TRADITIONAL RADIOGENIC ISOTOPE ANALYSES

We analyse routinely traditional radiogenic isotopes that are commonly applied to a wide range of water, soil and hard-rock samples. These include Sr (Neptune & Triton), Nd (Neptune and triton), Hf and Pb (both Neptune) isotopes.

For ancient samples, we perform isotope dilution analyses for high-precision ratios and concentrations of Rb-Sr, Sm-Nd and Lu-Hf. 

NON-TRADITIONAL STABLE ISOTOPES

We are specialised in the analyses of non-traditional stable Fe isotopes. We further measure Cu, Zn, Ni, Mo, Rb, Zr, and Ag isotopes in a selection of samples. All of these analyses are performed on the Neptune+.

Stable Nd isotopes are performed via TIMS (Triton+) using the double spike technique.

TRADITIONAL STABLE ISOTOPES

We routinely analyse O-H isotopes in water samples with our Delta instrument.

TRACE ELEMENT ANALYSES

...

GEOCHRONOLOGY

For the dating of accessory mineral phases we use isotope dilution for high-precision geochronology of garnet (Sm-Nd, Lu-Hf) and mica (Rb-Sr). We further perform in-situ analyses with our laser ablation systems on zircons, monazites, titanites, rutiles, and mica.

SPLIT-STREAM ANALYSES

Split stream analyses relate to the combined analyses of dating, isotope ratio and trace element analyses using a single laser spot (on a mineral) and 2-3 different mass spectrometers contemporaneously. For this, we simply split the gas stream to the instruments.
