This tender offer is for a double focusing, high-precision multicollector (MC) inductively coupled plasma mass spectrometer (ICPMS) for isotope ratio measurements. This instrument will be a part of a new analytical facility in the Department of Geoscience at Aarhus University serving primarily geoscience, as well as, many other fields including archaeology, biology, material science and engineering, medicine, among others. The instrument we are seeking must be robust, versatile and capable of analysing a wide range of isotopic systems by solution and solid-sample introduction systems, including Li, B, Mg, K, Si, Cr, Fe, Ni, Cu, Zn, Sr, Sn, Ce, Nd, Yb, Hf, Hg, Th and U.
