一、标准液的配制和浓度调整为了计算简便,快速分析中标准液浓度均作为F=1。间接法配制的标准液浓度总是或高或低,需要根据标定浓度调整。其方法据文献[麦维歧:药房制剂分析,111页,人民卫生出版社,1965]介绍有二:1.高浓度调低时,可直接加水稀释;2.低浓度调高时,要先加一定量试剂调浓,标定后稀释(或用浓标准液调整)。显然1法简便快速,所以
First, the standard solution preparation and concentration adjustment In order to calculate the simple, rapid analysis of standard solution concentrations are as F = 1. Indirect method formulated standard solution concentration is always high or low, need to be adjusted according to the calibration concentration. The method according to the literature [Maiweiqi: pharmacy preparation analysis, 111 pages, people’s health publishing house, 1965] there are two: 1 high concentration down, you can directly add water dilution; 2 low concentration, Add a certain amount of reagent to adjust the concentration, dilute after calibration (or adjust with concentrated standard solution). Obviously a simple and fast method, so
