“…These are part of the NIST SRM 610–617 series of glasses described in detail by Kane (1998). However, it is understood that inaccuracies using non‐matrix‐matched reference materials do exist to varying degrees depending upon analytical technique (Strashiem and Brandt 1967, Burnett et al . 2015).…”

The attractive physical and chemical properties of corundum lend to this material’s importance in both its natural and synthetic forms. However, much of the quantitative work performed on this material is plagued by unknown inaccuracy as non‐matrix‐matched reference materials are used. To conduct accurate quantitative analysis using SIMS, matrix‐specific relative sensitivity factors (RSFs) were determined for eighteen trace elements in corundum using dose‐verified ion implants. The RSF values ranged from 2.56 × 1022 to 3.29 × 1024 cm‐1 with total combined uncertainty values ranging from 7 to 10%. The RSF values, which are related to ionisation potentials, showed trends consistent with expectations for an insulating oxide. The developed values were applied to calibrate reference materials for LA‐ICP‐MS and to study other natural and synthetic corundum samples. A measurement reference material calibrated for Mg, Si, Ti, V, Fe and Ga produced consistent results over ten sessions in 4 years with relative standard deviations per trace element of 5% or less, confirming the repeatability of our process. A key finding was that calibrating LA‐ICP‐MS with NIST SRM 610 and 612 glasses to analyse corundum resulted in under‐reporting trace elements Be, Ti, V, Fe, Co, Ni and Ga compared with using matrix‐matched reference materials.

“…Techniques range from a small dilution to obtain a matrix correction factor to the addition of high levels of diluent so that sample and standard will have a common matrix (117,209,211,346,471,472,483,485,486). More details of the borax dilution are covered in the section on sample preparation and standards.…”

“…Fusion eliminates particle size effects and drastically reduces interelement effects. Sensitivity is only slightly reduced as a result of dilution by borax (255,471,484). There were several critical studies made of the borax fusion procedure that included factors such as temperature, fusion time, sample-to-flux ratio, and particle size effects (330,482,468).…”

Nous avons appliqué la méthode de double concentration, dont nous rappelons brièvement le principe, à la détermination précise des constituants majeurs et mineurs, soit Fe2O3 MnO, TiO2, CaO, K2O, P2O5, SiO2, Al2,O3, MgO et Na2O, dans les roches silicatées ou apparentdées. Dans ce cas, la technique de la double mesure permet de corriger pour l'effet interélément avec une précision relative théorique de l'ordre de quelques dixièmes de pour cent et nous avons pu grâce des précautions particuliéres en ce qui concerne la préparation des “perles” vitri‐ fiées et la mesure des intensités nettes, porter la precision pratique à un niveau comparable. Une étude exploratoire alors menée sur quatorze roches étalons (dont sept du Centre de Recherches Pétrographiques et Géochimiques de Nancy et sept de l'U.S. Geological Survey à Washington) nous a conduits à des résultats très satisfaisants, en ce sens qu'ils concordent généralement avec les valeurs “recommandées” dans la limite de ±1 pour cent, voire mieux, en valeur relative. Un petit nombre de valeurs recommandées ou proposées, dans le domaine des très faibles concentrations, peuvent même être contestées ou améliorées. Cette méthode simple et directe qui nous dispense d'avoir recours à toute espèce de coefficients d'influence ou de para‐ mètres fondamentaux, ainsi qu'aux machines, est quasi‐absolue. On peut I'employer avec avantage non seulement pour l'analyse des roches et des composés similaires, mais aussi et même avec une précision encore accrue pour l'analyse des minerais en général.
