Development of a Matrix-Matched Barite Reference Material (NWU-Brt) for Calibration of In Situ S Isotope Measurements by Laser Ablation Multi-Collector Inductively Coupled Plasma-Mass Spectrometry
A new matrix-matched reference material (NWU-Brt) with sulfur isotope ratios resembling those of natural barites has been developed for in situ S isotope measurements by laser ablation multi-collector inductively coupled plasma-mass spectrometry (LA-MC-ICP-MS). A 100 g quantity of natural barite crystal was milled to ultra-fine particles and sintered to a solid block using a fast hot-pressing sintering technique (FHPS). We report δ34S ratios determined by isotope ratio mass spectrometry (IRMS), solution nebuliser multi-collector inductively coupled plasma-mass spectrometry (SN-MC-ICP-MS) and LA-MC-ICP-MS, involving up to six participating laboratories. The homogeneity of δ34S ratios of the synthesised barite was tested by LA-MC-ICP-MS with an analytical spot size of 53 μm. The LA-MC-ICP-MS results show that NWU-Brt demonstrates a satisfactory homogeneous composition and is an appropriate material for calibrating δ34S ratios in barite. IRMS and SN-MC-ICP-MS produced mean δ34S values of +14.17 ± 0.42‰ (2s) and +14.27 ± 0.23‰ (2s), respectively. The results of LA-MC-ICP-MS analyses are consistent with the IRMS and SN-MC-ICP-MS ratios within uncertainty. Overall, our results confirm the suitability of NWU-Brt for the calibration of δ34S ratios in barite using LA-MC-ICP-MS.
