摘要
根据我国煤炭资源的总体分布和煤产品的实际需要,研制了16种煤炭标准物质。定值分析方法为国家标准方法,定值项目包括常规指标和部分微量元素。针对煤炭标准物质稳定性差的缺点,研制过程中采取了多种措施,力求改善稳定性,延长有效期。
16 coal standard reference materials have been prepared,which approximately represented the typical coal resources and coal products in China.Standard analytical methods were used in certification.Common components and some trace elements were certified.More attention was paid to stability of the coal standard reference materials and some effective measures were taken to improve the stability and to extend the validity period of the coal standar reference materials.
