前言目前,人体生物材料中痕量金属元素水平与疾病和健康的关系问题,已引起国内外学者的关注。监测人体生物材料中痕量金属元素含量的工作日益增多。由于生物材料品种繁多,基体组成复杂,因而使用不同测定方法获得的数据的准确性是一个值得探讨的问题。标准物质是已确定其一种或几种特性,用于校准测量器具,评价测量方法或确定材料特性量值的物质。随着分析化学的发展,国内外研制和推广使用了一些生
Preface At present, the problem of the relationship between trace metal elements in human biological materials and disease and health has drawn the attention of scholars at home and abroad. There is a growing body of work to monitor trace metal elements in biomaterials. Due to the variety of biomaterials and the complexity of matrix composition, the accuracy of the data obtained by different measurement methods is a problem worth exploring. Reference material is one that has identified one or more of its characteristics, used to calibrate a measuring instrument, to evaluate a method of measurement, or to determine the magnitude of a material characteristic. With the development of analytical chemistry, some students have been developed and popularized at home and abroad
