TIMS

Our current TIMS instrument is a 2004, nine moveable Faraday cup collector, single ion multiplier Thermo-Fisher Triton. The Triton has state of the art sensitivity and accuracy and is

used in positive ion mode (P-TIMS) for isotopic analyses of Sr, Nd, Ba, Sm, Pb and Cr. In negative mode (N-TIMS) it is used primarily for Os.
