The inductively coupled plasma-triple-quadrupole-mass spectrometer coupled to a laser ablation system (LA-ICP-QQQ-MS) is being developed to measure multiple sulfur isotopes.

Digests of isotopically characterized pyrite (Sierra pyrite, LaFlamme et al. 2016) have been tested by ICP-QQQ-MS with Bastian Goerg, Senior Scientist Agilent Scientific and have promising results:

We are now actively analysing S isotopes by LA-ICPMS using our characterised reference materials for pyrite, chalcopyrite and pyrrhotite. Please contact crystal.laflamme@ggl.ulaval.ca

We are also completed trace element analyses and maps in a wide-variety of minerals including sulfides, oxides, silicates.
For more information about our method and capabilities, see this recent abstract presented at GACMAC 2022 (Halifax) and SGA 2023 (Zurich) by Guillaume Barré and Crystal LaFlamme:
