    Description

    TIMS is a magnetic sector mass spectrometer designed for high precision isotope ratio measurements. Our TIMS facility, built around the ThermoScientific Triton-Plus mass spsectrometer, specilaizes in analysis of radiogenic isotopes, but is also capable of measuring non-radiogenic isotope ratios from solid and liquid matrices. Compared to the MC-ICP-MS, the TIMS affords higher precision, lower throughput. alternative for strontium (Sr) and calcium (Ca) isotopic ratio analysis. Examples of other isotopic analyses using the TIMS include:

    Rb-Sr geochronology
    Sr isotopic analysis
    Ca isotopic analysis
    U-series isotopic analysis*
    Pb isotopic analysis*
    Sm-Nd geochronology*
    Nd isotopic analysis*
    * Methods are not yet developed in our laboratory. Please contact our laboratory for updates

    Prior to analysis, samples are acid-digested and elements of interest are purified using traditional ion chromatography techniques. Currently, Sr, Ca, and Rb may be isolated using the ESI Prepfast automated ion chromatography system, allowing for higher sample throughput compared to traditional gravity-fed column chemistry. For solid samples, in-situ isotopic analysis can be achieved using the ESI Micromill housed in our facilities.
