摘要
根据我国煤炭检测的实际需要,制备了煤中15种微量元素系列标准样品。介绍了煤中微量元素标准样品制备过程中的一种高均匀性定量分装方法,并对样品的均匀性、稳定性进行了详细研究,确保所制备的煤中微量元素系列标准样品均匀性和稳定性良好,符合国家标准样品的要求。
According to the actual needs of Chinese coal testing,a series of 15 types of reference samples of trace elements in coal were prepared.This paper introduced a high homogeneity quantitative fractional pack method in reference sample preparation process of trace elements in coal,meanwhile,the homogeneity and stability of sample were studied particularly,which would ensure good homogeneity and stability for this series of reference samples,and make them meet the national standard sample requirements.
