| Abstract: | Four reference materials of chrimote were developed according to the need of chrimote reference materials in our country. The content of Cr2O3 ranged from 17.59% to 57.80%. The analytical results indicated that the reference materials were uniform and stable. A multi - laboratory collaborative analysis scheme was adopted in the certification procedure. Certified values of 16 components were assigned and the proposed value of FeO and CO2 was given. |
