New Calcium Carbonate Nano?particulate Pressed Powder Pellet (NFHS?2?NP) for LA?ICP?OES, LA?(MC)?ICP?MS and µXRF

A new matrix-matched reference material has been developed – NFHS-2-NP (NIOZ Foraminifera House Standard-2-Nano-Pellet) with element mass fractions, and isotope ratios resembling that of natural foraminiferal calcium carbonate. 180–355 µm size fraction planktic foraminifera was milled to nano-particles pressed pellets. We report information values for fractions forty-six elements measured by six laboratories as well 87Sr/86Sr (three laboratories), ?13C, ?18O (five laboratories) 206,207,208Pb/204Pb (one laboratory) determined ICP-MS, ICP-OES, MC-ICP-MS, ratio spectrometry, WD-XRF TIMS. Inter- intra-pellet elemental homogeneity tested using multiple LA-ICP-MS analyses in two applying spot sizes 60 70 µm. The results most the relevant proxies palaeoclimate research show RSD < 3%, demonstrating a satisfactory homogeneous composition. Homogeneity pellet verified repeated LA-MC-ICP-MS laboratories. Information are reported Pb values. these systems remains be secondary-ion spectrometry. Overall, our confirm suitability calibration or monitoring quality situ geochemical techniques.
