产品详细介绍
CD-1锑矿石成分分析标准物质Antimony Ore Sb：3.57 ± 0.04
Certified Reference Material: Antimony Ore
CD-1 was prepared in 1975 from ore of the Lake George mine of Consolidated Durham Mines and Resources Limited at Prince William, New Brunswick. It contains significant concentrations of antimony and arsenic and, thus, should be especially useful in assessing methods in which there is potential interference between these elements. The following minerals are present in approximately decreasing order of abundance: quartz, mica, clay minerals, stibnite, pyrite, arsenopyrite, pyrrhotite, and traces of chalcopyrite and chalcostibite. The approximate chemical composition of CD-1 is given in the table in the next column.
Twenty laboratories provided analytical results for either antimony or arsenic, or both.
A copy of CANMET Report 77-63, "Antimony-arsenic ore CD-1: A certified reference material", will be issued with each order of CD-1.
