Les MC-ICP-MS Neptune et Neptune Plus sont des spectromètres de masse multi-collecteur à source plasma. Ils permettent de mesurer des compositions isotopiques pour toute une gamme d’éléments, des plus légers au plus lourds (Li, B, Mg, Si, K, Ca, Cr, Fe, Ni, Cu, Zn, Sr, Nd, Pb, etc…).
Ils peuvent être couplés à un désolvateur (Apex HF, Apex IR, Apex Oméga) pour les échantillons en solution ou à un laser (Analyte G2 193nm ArF Excimer) pour les échantillons solides.
Le CRC-MC-ICP-MS Sapphire présente quant à lui la particularité de posséder une cellule de collision/réaction dans laquelle des gaz (e.g., He, H2, O2, N2, SF6) peuvent être utilisés pour s’affranchir de l’40Ar et des interférences polyatomiques associées (e.g., 38ArH+ sur 39K+, 40Ar+ sur 40Ca+, 40Ar14N+ sur 54Cr+ et 54Fe+, 40Ar16O+ sur 56Fe+, 40Ar23Na+ sur 63Cu+).
Les MC-ICP-MS de la plateforme PARI s’inscrivent au niveau national au sein de l’infrastructure de recherche RéGEF du CNRS-INSU (dans le réseau spectrométrie TIMS, MC-ICPMS & LA-ICPMS).
