在多数制剂中,即使存在微量溶解的氧也是有害的,注射剂的氧化也涉及许多重要和复杂的问题,通过取决于精确测定溶液中的氧含量。这些方法分为化学、气相层析、电测量等几个部分,尤其着重于化学分析的Winkler方法和复盖膜极谱检测法。前者在氧测定中是一种基本的方法,后者可能成为具备应用、迅速、易行及准确的合适方法。 Winkler方法约一百年前,Winkler方法已成为测定水中溶解分子氧的经典方法,目前文献中绝大多数溶解氧的数据直接或间接来自此法。该法灵敏、定量和简便,决定了它的普遍性。可用4个化学方程式来概括:
In most formulations, even slight amounts of dissolved oxygen are detrimental, and the injection of the oxidant involves a number of important and complex issues, depending on the precise determination of the oxygen content in the solution. These methods are divided into chemical, gas chromatography, electrical measurement and other several parts, with particular emphasis on chemical analysis Winkler method and covered membrane polarographic detection method. The former is a fundamental method in oxygen determination and the latter may be a suitable method for application that is rapid, easy and accurate. Winkler method About a hundred years ago, the Winkler method has become a classical method for the determination of dissolved molecular oxygen in water. Most of the data on dissolved oxygen in the literature are derived directly or indirectly from this method. Sensitive, quantitative and simple, the law determines its universality. Available in 4 chemical equations to summarize:
