Device: Neptune Plus multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) with an Apex-Q desolvation nebulizer or a self-aspirating nebulizer, depending on sample type and overall strontium concentration in the sample.
Strontium isotope ratio data are reported as 87Sr/86Sr ratios. The analytical accuracy and precision were assessed by multiple measurements of certified reference material (SRM 987) during the analysis. Uncertainties for each sample measurement is presented as the 95% confidence interval (CI).
Note: The lab offers strontium concentration for an additional fee only in conjunction with the isotope measurements.
