Özet:

 


 Several analytical methods are being employed related to various research projects and routine works
on water samples in hydrogeochemistry laboratory of General Directorate of Mineral Research and Exploration. Some
statistical evaluations are necessary in order to obtain accurate results for the projects related. In order to control the
precision and accuracy of the chemical determinations in our laboratory, standard water samples have been requested from
EPA (Environmental Protection Agency, USA). The samples donated by EPA have been analyzed for 28 species using our
standard methods. Results of the determinations were compared with the true values supplied by EPA using «Studend's t
test». R values have been used to investigate the presence of systematic errors at 95 % an 99 % confidence levels. Accuracy
and precision of the analytical methods used have been statistically determined. No systematic error was observed for
43 results of the total of 54. Evaluation for systematic error could not be realized for 11 results. Relative percent errors
were found to be in the ranges at 0-10, 11-20, 21-50 and more than 50 for 33, 10, 6,5 results respectively. As a result
of this study, by applying the statistical tests for accuracy and precision, it has been determined that accurate results
are obtained in most of the methods, only two methods require further development.
