苯甲醇注射液中加入适量的氯化钠调等渗己有报道。苯甲醇和氯化钠均有折光性,溶液的浓度与它的折光率呈直线相关,本文采用折光法测定其含量,并与紫外分光光度法作了对照(苯甲醇注射液
Benzyl alcohol injection by adding an appropriate amount of sodium chloride isotonic dialysis has been reported. Benzyl alcohol and sodium chloride all have the property of refraction. The concentration of the solution is linearly related to the refractive index of the solution. In this paper, the content of the solution is measured by refractive index method and compared with UV spectrophotometry (benzyl alcohol injection
