Methods are presented for the precise determination of Mg/Ca, Sr/Ca, Cd/Ca, Zn/Ca, Li/Ca, U/Ca, Mn/Ca, and Fe/Ca by sector field ICP‐MS. Analytical precision is largely independent of sample size over the range of ∼5 to 125 μg CaCO<jats:sub>3</jats:sub>, eliminating the need for narrow target dilutions. Long‐term 1σ precisions are as follows: Mg/Ca = 0.54%, Sr/Ca = 0.57%, Cd/Ca = 1.8%, Zn/Ca = 3.2%, Li/Ca = 0.88%, U/Ca = 1.9%, Mn/Ca = 0.97%, and Fe/Ca = 1.4%. For Mg/Ca, actual foraminiferal samples appear to give reliable results below 10 μg CaCO<jats:sub>3</jats:sub> (postcleaning mass).</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994805670656","@type":"Researcher","foaf:name":[{"@value":"Thomas M.
