摘要: 介绍几种Ｈ－ｐｏｉｎｔ法，并与常见的计算分光光度法进行了比较。将Ｈ－ｐｏｉｎｔ法用于复方盐酸丁卡因注射液测定的数据处理，表明Ｈ－ｐｏｉｎｔ法有效地消除干扰，有较高的精密度和准确度。盐酸丁卡因回收率为：Ｈ－ｐｏｉｎｔ法１０１．０％，ＲＳＤ为２．７％（ｎ＝７），Ｋ系数Ｈ－ｐｏｉｎｔ法９９．１％，ＲＳＤ为１．８％（ｎ＝７），三波长Ｈ－ｐｏｉｎｔ法９９．６％，ＲＳＤ为１．４％（ｎ＝７）。Abstract: A set of new analytical methods for the determinaton of tetracaine hydrochloride in compound Injection of Tetracaine Hydrochloride are proposed by using different H point standard additions method.By proper selection of the combination of wavelengths,the
