Contract Services in Isotope Geochemistry
Ca, Sm, Nd, Rb, Sr, U, Pb

 

We perform U, Pb, (Rb), Sr, Sm, and Nd concentration analyses by isotope dilution mass spectrometry or equivalent methods. Our facility includes ultraclean Class-100 laboratories with controlled temperature and humidity for weighing, dissolving and processing samples. Isotope ratios are determined using a Triton TI thermal ionization mass spectrometer. We include the results for internationally recognized isotopic standards with all our contract work. Please note that we only offer Rb determinations on mineral separates.

Although we can, in rare circumstances, carry out mineral separations, we prefer that mineral separates and/or rock powders are prepared and provided by the requestor. All powders should be inspected for homogeneity under a binocular microscope prior to shipping them to us. Please do not provide powders in paper or plastic bags - centrifuge tubes or small plastic/glass vials should be used.
