以硬石膏矿物标样中Ca相对于S的灵敏度因子为基准,将玻璃标样中主量和痕量元素相对于Ca的灵敏度因子转换成元素相对于S的灵敏度因子,建立了多玻璃标样结合硫内标归一定量技术分析硫化物单矿物多元素的新方法。利用本方法分析了美国合成多金属硫化物矿物标样MASS-1中20种元素,主量元素分析结果的相对误差小于10%,痕量元素分析结果几乎都落在给定值±不确定度范围内。利用本方法对12个硫化物单矿物分析结果表明,绝大多数主量元素含量测定值的相对误差小于10%,且多数主量元素甚至优于以MASS-1为外标、内标归一定量法及内标校准法分析结果,而痕量元素与MASS-1校准结果较为一致。本方法克服了基体不匹配的问题,能比较准确地定量分析硫化物矿物中的主成分S,可用于定量校准硫化物矿物。
Based on the sensitivity factor of Ca relative to S in the anhydrite reference sample, the sensitivity factors of the major and trace elements relative to Ca in the glass standard were converted to the sensitivity factors of the element relative to S. A multi-glass standard A New Method for Analyzing Multiple Elements of Sulfide Single Minerals by Sulfur Assigned to a Certain Quantity of Technology. This method was used to analyze the 20 kinds of elements in MASS-1, a standard sample of synthetic polymetallic sulphides in the United States. The relative error of main elemental analysis was less than 10%. The results of trace element analysis almost all fell within the given values ± uncertainty Range. The results of single sulphide analysis using this method show that the relative errors of the contents of most major elements are less than 10%, and most of the major elements are even superior to those with MASS-1 as the external standard and the internal standard of the same Quantitative method and internal standard calibration analysis results, and trace elements and MASS-1 calibration results are more consistent. The method overcomes the problem of matrix mismatch, can quantitatively analyze the main component S in sulfide minerals more accurately, and can be used for quantitatively calibrating sulfide minerals.
