The Thermo Triton Plus is a state of the art multi-collector Thermal Ionization Mass Spectrometer equipped with 9 Faraday collectors, 4 ion counters along with a RPQ. We routinely analyze Sr, Nd and Ca stable isotopes (check back for more updates). For more details on our instrument, visit:

Sample preparation
- Prior to analysis, the element of interest has to be separated from the sample matrix by ion-exchange chromatography in a clean lab.
- High-purity reagents and water should be used to keep blanks low.
- The purified sample is dried and loaded on Re/Ta/W filaments using dilute acids (e.g. nitric, phosphoric) with or without additional emitters/activators (e.g. silica gel, boric acid). Loading is done in the TIMS lab.
