| Summary: | Introduction. Different approaches are used for transfer of impurities determination methods. In most cases, comparative testing of samples or partial validation of methods is performed. At the same time, a number of issues important for practice are still relevant.Text. The features of methods validation and comparative testing of samples during the transfer of impurities determination methods are considered. Potential acceptance criteria – requirements to the permissible difference between results of transmitting and receiving laboratories – are given. The calculation formulas of the TOST test are considered, and the critical condition for the comparative testing of samples is given. The key points that should be taken into account when transferring the methods are discussed.Conclusion. The data and recommendations are presented, which are important for increasing the reliability of the transfer of the impurities determination methods. |
