注射用粉剂装量差异的检查一般都是采用称重法,由于要经过洗滌干燥等步骤费时较长,在切割安瓿时,常易有细小玻璃屑落入,导致结果不够准确,但却不易发现。为了克服上述缺点,需要寻找一种简捷可靠的测定粉剂装量的方法,以代替原来的称重法。在快速分析中采用折射率测定法于很多溶液剂的定量工作,因而联想到用这种方法于装量差异的 Injection powder dosage is usually checked by weighing method, due to go through washing and drying and other steps takes a long time, cutting ampoules, it is often easy to have small pieces of glass fell into pieces, resulting in the results are not accurate enough, but not easy to find . In order to overcome the above shortcomings, it is necessary to find a simple and reliable method for measuring the amount of powder to replace the original weighing method. In the rapid analysis of the refractive index determination of the solution in a lot of quantitative work, so think of this method in the loading capacity of the difference
