火焰光度法测定血清钠的计算方法,国内大多数专业书籍皆介绍了一点标准:“直接计算法”。也有作者提出用“减截距计算法”。个别书上提到了“多点标准法”。本文依据火焰光度法中发射光谱强度与被测物浓度的实验式,认为用“双对数转换后回归法”进行计算比较简便实用。 Flame photometric method for the determination of serum sodium, most domestic professional books are introduced a little standard: “direct calculation method.” Some authors also proposed using “subtraction intercept method.” Individual books mentioned the “multi-point standard method.” In this paper, based on the experimental results of the intensity of emission spectrum and the concentration of analyte in the flame photometric method, it is more convenient and practical to calculate with the “double logarithmic regression method.”
