This material is extracted from the part, for readers to pharmacy drug inspection work reference. In the future will continue to choose to load. - Editor One, the general operation of rapid quantitative determination 1) rapid determination, according to the seizure of the nature and amount of different choice of 0.1 or 0.02 N titration solution. 0.02 N titration solution is mainly used for the determination of poisonous drugs (such as alkaloids, etc.) and high molecular weight substances. 2) When weighing the liquid preparation should take ml (capacity). If the solution concentration is higher than 2 ~ 3%, calculate the proportion should pay attention to. When the total concentration of a solution containing a plurality of ingredients is 4 to 5%, the average specific gravity is 1.025 to 1.035 (see the following table for the specific gravity of a solution).
