Thermal Ionization Mass Spectrometer

Jan 11, 2021 Fundamental Principles of Thermal Ionization Mass Spectrometry (TIMS) A TIMS is a magnetic sector mass spectrometer that is capable of making very precise measurements of isotope ratios of elements that can be ionized thermally, usually by passing a current through a thin metal ribbon or ribbons under vacuum. The ions created on the ribbon (s) are accelerated across an electrical …

Mar 30, 2020 Thermal Ionization Mass Spectrometry Facility. The Thermal Ionisation Mass Spectrometry Facility (TIMS) provides highly accurate and precise measurements of the isotopic composition of elements using TIMS TritonTM instrument, including sample preparation in clean contamination-free environment.

ABSTRACT A static double collector system in the Finnigan-MAT 262 thermal ionization mass spectrometer was used to analyse different amounts of the boric acid standard NBS SRM 951 and natural samples. The main objectives of the study were to improve precision and accuracy of B isotope measurement, and to define the critical minimum amount of B ...

Rationale: A new compact thermal ionization (TI) mass spectrometer, for the isotope ratio analysis of the elements relevant to nuclear applications, has been designed and developed. The new development offers superior performance in terms of sensitivity, precision and a compact footprint in comparison with the conventional one.

Analytical Techniques The TRITON is a multicollector thermal ionization mass spectrometer capable of delivering accurate and precise results for both positive and negative ion measurements.

Aug 18, 2017 Thermal ionization mass spectrometry (TIMS) is widely accepted as the gold standard for high performance isotopic measurements and has long served as the workhorse in the isotopic ratio determination of nuclear materials. Nuclear forensic and safeguard specialists have relied heavily on such methods for both routine and atypical efforts.

Jan 01, 2001 Mass spectrometric U-series dating of speleothems from Tangshan Cave, combined with ecological and paleoclimatic evidence, indicates that Nanjing Man, a typical Homo erectus morphologically correlated with Peking Man at Zhoukoudian, should be at least 580 k.y. old, or more likely lived during the glacial oxygen isotope stage 16 (∼620 ka). Such an age estimate, which is ∼270 ka …

The Thermo Scientific™ TRITON Plus thermal ionization mass spectrometer sets another standard in high-precision TIMS isotope ratio measurements. It builds upon the strong field-proven reliability and cutting-edge technology from the TRITON instrument: high sample throughput, variable multi-collector, zoom optics, and multi-ion counting.

A temperature ( 1 F) controlled, HEPA-filtered, positive pressure room (ERB-5116A) houses two thermal ionization mass spectrometers acquired through National Science Foundation Major Research Instrumentation grants: the IsotopX Isoprobe-T mass spectrometer delivered in fall of 2006 and moved to the ERB in summer 2011, and the IsotopX Phoenix X62 mass spectrometer installed in spring 2014.

The Thermal Ionization Mass Spectrometry (TIMS) Laboratory is maintained by Professor Elizabeth Griffith. The laboratory, which is supplied with HEPA filtered air, includes: a room that houses a thermal ionization mass spectrometer, and a separate state-of-the-art cleanroom for low-blank separation of elements for mass analysis.

The thermal ionization mass spectrometer facility at Duke University, analyzes the isotopic composition of trace elements in rocks, sediments, water, and environmental samples. We are engaged in research in geochemistry, marine chemistry, paleoclimate, geochronology, radiogenic isotope studies, and stable isotope geochemistry.
