| Abstract: | The repeatability and durability of the method to determine the contents of acid soluble substances in medical talc powder (MTP) and the main influence factors are discussed in this paper. The influence effect on the differences of the determination results of the filtering media of acid soluble extraction solution is analyzed on the basis of the contents of acid soluble substances measured at random by weighing method. There is not obvious difference in determinations made by different filters and laboratories. The RSD values of the contents for equal rank samples of 30 batches MTP are 0.0%~18.2%. There are some problems in the repeatability and durability of the method to determine the contents of acid soluble substances in the MTP. It is necessary to change the content limits relatively. |
