采用蒽酮法测定右旋糖酐溶液的浓度。研究了影响测定结果的因素，并提出了提高测定精度的方法。分析了测定过程中的误差来源，认为最可能的误差来源是空白的变异。测试了不同浓度水平的19种不同化学品对分析的影响。通过计算97组重复空白测定和345组重复样品测定的标准偏差，估计方法的精密度。样品的标准偏差（吸光度单位）为0.0029，相当于吸光度水平为0.600时的0.48%。
The anthrone method was used for the determination of concentration of dextran solutions. The effects of the factors involved in the method were studied and a procedure designed to improve the preci-sion was evolved. Sources of error in the proce-dure were analyzed andit was concluded that the most probable source of error is variation in the blank. Nineteen different chemicals at different levels of concentration were tested for their effects on the analysis. The precision of the method was estimated by calculating standard deviations from 97 sets of duplicate blank determinations and 345 sets of duplicate sample determinations. The standard deviation for the samples, in absorbance units, is 0.0029, corresponding to 0.48% at an absorbance level of 0.600.
