在复方制剂的快速分析中,经常遇到先利用某种标准溶液滴定几种成分的共同性质,以求得这几种成分的总量,然后利用特定的标准溶液滴定其中某一成分,反过来确认其中另一成分或几种成分的含量情况。根据常见的全国各省、区医院制剂手册所记载的这方面的计算问题提出两点予以讨论。一、复方制剂各种成分的限量计算问题例如:复方碘溶液的快速分析:
In the rapid analysis of compound preparations, it is often encountered to titrate several components first with a standard solution to determine the total amount of these components, and then use a specific standard solution to titrate one of the components, and vice versa Confirm the content of one or more of the other ingredients. According to the common national provinces, district hospital preparation manual recorded in the calculation of this issue raised two points to be discussed. First, the compound formulations of various components of the limited calculation example: Compound iodine solution rapid analysis:
