| Abstract: | The optimum parameters are seleted by means of orthogonal design for determination of Sr concentration in rock samples by flame-free AAS.
44 measurements in 3 sets of orthogonally designed experiments were performed with good results. In addition, variation trends caused by different factors and uncertainties can be evaluated by direct analysis and variance analysis, data can be processed by mathematical statistics in orthogonal design. Therefore, the results are more reliable. This paper is a good beginning of the application of orthogonal design in different fields. |
