原始语种摘要: Abstract(#br)We present new high precision Os isotope data obtained by solution-mode MC-ICP-MS for 4 different Os isotope reference materials and compare the data to that obtained by the N-TIMS method. Mass fractionation effects for MC-ICP-MS are evaluated and we demonstrate excellent adherence to the exponential law. An improved and robust method for the derivation of interfering element isotope ratios is presented and evaluated via analysis of solutions with widely varying interfering element/analyte ratios. We show experiments that illustrate the extent of memory with a conventional solution introduction system and establish a protocol that reduces washout time and memory effects to the same level as those common for other elements typically analysed at high precision by...
