Sr Isotope Analysis of Picogram-Level Samples by Thermal …

Thermal ionization mass spectrometry (TIMS) has shown excellent analytical precision for Sr isotopic ratio analysis, even for small masses of material (0.5–10 ng). However, because of the sensitivity limit of TIMS, it is still not possible to obtain high precision 87 Sr/ 86 Sr isotope ratios for picogram-level sample sizes (30–100 pg) due to the lack of a highly sensitive emitter.

Thermal Ionization Mass Spectrometry (TIMS)

To obtain high precise isotopic information from metal element systems, Thermal Ionization Mass Spectrometry is one of the most suited techniques. It consists of a thermal ionization source, where ions are generated and accelerated under vacuum, a magnetic sector where the ions get separated according to their m/z ratio and a detection system where the ions beams get converted to voltage.
