中文词条名差示分光光度法 英文词条名differential spectrophotometry 分光光度法中样品中被测组分浓度过大或浓度过小(吸光度过高或过低)时测量误差均较大为克服这种缺点而改用浓度比样品稍低或稍高的标准溶液代替空白试剂来调节仪器的100%透光率对浓溶液或0%透光率对稀溶液以提高分光光度法精密度准确度和灵敏度的方法称为差示分光光度法差示分光光度法又可分高吸光度差示法低吸光度差示法精密差示分光光度法等
几种颇有应用潜力的光谱分析方法：一、差示分光光度法(Difference Spectrophotometry)：简称ΔA法。取两份相等的供试液，一份加酸，另一份加碱或缓冲液或其他能够发生某种化学反应的试剂，有时也可不加任何溶液，然后...
