【摘要】 <正> 采用感应耦合等离子体(ICP)方法来从事血液研究的曾见有Fassal,Greenfleld的报导。他们在克服基体问题上采取标准加入的方法;为了去除基体,也有人用硝酸,过氯酸硝化处理样品;近年Mermet等人采用稀释样品的方法,基体影响虽被克服了,但灵敏度却相应降低,对此问题我们在实验中摸索到用增加标样中电解质(NaCl)浓度的方法,这方法既克服了基体影响又不影响分析灵敏度,比较简便。本文介绍对血清中的磷、铁、锰、铜、锌、钙、镁等元素的一次同时测定。其中可测更多还原

【Abstract】 A method of inductively coupled plasma spectrometry is presented for the simultaneous determination of microamounts of P, Fe, Cu, Zn, Mg, Mn and Ca in human serum. This method is found useful to determine the minimun concentration of Mn 1—2 ppb and the maximum concentration of P 150 ppm. The analytical results are in accordance with those of atomic absorption spectrophotometry. The method has been used efficiently to control the concentration of electrolyte in standard sample for eliminating matrix effect with pretty good precision.更多还原
