血中痕量元素的测定是对诊断或了解机体代谢的情况均极有价值。例如,血清中铜的浓度显然与恶性淋巴瘤及治疗效果有关。钴能改变肾的红细胞生成因子,对它的测定也与B_(12)的代谢有关。临床化学中血清锰浓度增高是心肌梗塞的最准确的指标之一。作者认为具有背景补偿的石墨雾化器法对生物体液及组织中锰、钴和铜的测定,可提供一个迅速、可靠而灵敏的方法。此法的优点是耗血量少、简便,从而减少了污染的危险性。此法可用市售的现成分析仪器,不需进行花钱太多而又很精
Determination of trace elements in the blood is the diagnosis or understanding of the body metabolism are extremely valuable. For example, the serum concentration of copper is clearly associated with malignant lymphoma and treatment. Cobalt can change the renal erythropoietin, and its determination is also related to the metabolism of B_ (12). Increased concentration of serum manganese in clinical chemistry is one of the most accurate indicators of myocardial infarction. The authors consider the graphite atomizer method with background compensation to provide a rapid, reliable and sensitive method for the determination of manganese, cobalt and copper in biological fluids and tissues. This method has the advantage of less blood consumption, simplicity, thereby reducing the risk of contamination. This method can be commercially available off-the-shelf analytical instruments, without having to spend too much and very fine
