We have two TIMS machine in the IES. Currently the old Triton (Thermo Fisher Scientific Inc.) supports routine Sr, Nd, and Os (negative ion mode) analysis. Small samples (nanogram level or lower) of Sr, Nd, and B (negative ion mode) are run on the new model Triton XT (Thermo Fisher Scientific Inc.). New methods are under development. Please contact Dr. Yi-Wei Liu if you have any interest in collaborating with us.
