Exploring the Quantity Traceability in the Certification Process of Oxygen Element Series Standard Samples in Molybdenum Metal
Based on the inert gas melting infrared absorption method and using potassium dichromate reference rea-gent as a calibration point,the determination of oxygen content in metal molybdenum has solved the problem of quantity traceability in the certification process of oxygen element series standard samples in metal molybdenum.The results of the comparative experiment on quantity traceability exploration are within the expanded uncertainty range,with precision RSD less than 10% and spiked recovery rates ranging from 90% to 110% .
