[Characterization of an analytical method, comparison between two methods and electronic elaboration of data...

An experimental scheme for the evaluation of two parameters of validity of an analytical method, precision and accuracy, has been reported. Particular emphasis has been given to the problem of comparison between two methods. In the description a validity limit of the scheme has been given and certain critical points, commonly encountered in the measurement of the above mentioned parameters during the preparatory as well as the experimental phase, has been underlined. Further, with the help of tables and graphs, an example for electronic elaboration of the data obtained during the course of standardization of an automatic method for the determination of uric acid in serum according to the above scheme, has been given.
