Multi-Collector Mass Spectrometers

The multi-collector mass spectrometer is a powerful tool that is particularly designed for measuring high precision isotope ratios. The Department is equipped with 6 different multi-collector mass spectrometers, including both MC-ICP-MS (Nu Plasma, Nu Plasma HR, Nu Plasma II, Nu 1700) and TIMS (Thermo Finnigan Triton) for different research and teaching purposes. We also have the prepFAST MC, an automated sample purification system, that can allow high sample throughput. The instruments provide a full range of analytical capabilities for measuring various isotopic systems in minerals, rocks, meteorites, sediments, waters, and biological samples, ranging from the land to the ocean, and from the Earth to the Moon.

In Oxford we are one of the few laboratories world-wide to have a great suite of novel mass spectrometers and advanced techniques. We have developed a wide range of analytical methods for measuring diverse isotopic systems (e.g. Li, Ca, V, Cr, Ni, Cu, Zn, Sr, Mo, Cd, Ba, Nd, W, Pb, Ra, Th, Pa, and U, please see our recent publications for references).

Our isotope research facilities can provide collaborative support for a wide range of stable and radiogenic isotope applications. If you have any enquiries, please contact Alan Hsieh for more information.
