TIMS 1/3

Our TritonTM TIMS instruments features a multicollector system consisting of nine Faraday cups and a secondary electron multiplier, multiple ion counting, and a 21-sample turret. The isotope dilution technique used is a ‘definitive’ method of analysis producing highest achievable accuracy and precision. TIMS represents the gold standard for isotopic analysis, reaching a precision of 0.001% on isotopic ratios. The history of TIMS-based research at Curtin can be traced back to the 1960s, when the isotope study group carried out Rb-Sr and Lu-Hf chronological studies. The facility has recently installed a Thermo Scientific TritonTM mass spectrometer, facilitating a new range of geochemical, geological and environmental research applications.

TIMS 2/3

The TIMS instrumentation, in combination with isotope dilution methodology, is widely used in chemical metrology for the calibration of isotopic standards, and the calculation of isotopic abundances and atomic weights.

TIMS 3/3

The TIMS Facility at Curtin University has contributed to accurately measuring the concentrations of various elements in international reference materials. The currently accepted atomic weights of Cd, Te and Sn are based on measurements made at Curtin. The present applications of TIMS are mainly in the broad field of geochronology involving Re/Os, U/Pb, Pb/Pb and Sm/Nd isotope systems, and in isotope fingerprinting in the study of ore- and petroleum formation processes.

STABLE ISOTOPE ACID DIGEST LABORATORY 1/2

Sample preparation and chemical separation of elements is carried out in the recently purpose-build Acid Digest Laboratory with clean air environment designed for ultra-trace analyses. It is equipped with ULPA-Filtered air to reduce particle levels, ducted fume cupboard and deionized distilled ultra-pure water.

STABLE ISOTOPE ACID DIGEST LABORATORY 2/2

The Clean Lab represents the latest evolution in the design of clean labs for processing ultra-trace amounts of heavy metals.

APPLICATIONS

The present applications of TIMS are mainly in the broad field of geochronology involving Re/Os, U/Pb, Pb/Pb and Sm/Nd isotope systems, and in isotope fingerprinting in the study of ore- and petroleum formation processes.
