布洛芬片在生产过程中发现，半成品、成品的含量测定结果比投料量偏低，需在工艺处方中补加布洛芬原料2%左右。认为其含量测定项的样品溶液配制方法不能准确反映出产品的实际质量水平，误差较大，为此，本实验改进样品溶液配制方法。 1 实验方法 1.1 方法Ⅰ 改进的样品溶液配 Ibuprofen tablets found in the production process, semi-finished products, finished products than the amount of low-volume test results, the need to add prescriptions Ibuprofen raw materials about 2%. It is considered that the content of the determination of the sample solution preparation methods can not accurately reflect the actual quality level of the product, the error is larger, therefore, this experiment to improve the sample solution preparation method. 1 Experimental Methods 1.1 Method I improved sample solution with
