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
Fassal and Greenfleld have reported on the use of inductively coupled plasma (ICP) for blood research. In order to remove the substrate, some people use nitric acid and perchloric acid to treat the sample. In recent years, Mermet et al. Used the method of diluting the sample, but the influence of the matrix was overcome, but the sensitivity was reduced correspondingly , This problem we found in the experiment to increase the concentration of electrolyte (NaCl) standard method, this method not only to overcome the impact of the matrix without affecting the sensitivity of the analysis is relatively simple. This article describes the serum of phosphorus, iron, manganese, copper, zinc, calcium, magnesium and other elements of a simultaneous determination. Which measurable
