Preparation of samples in the analysis of the measurement process,[link widoczny dla zalogowanych], sample preparation is to analyze the results good or bad or right key. in general sample preparation, the samples required L4turn cross section above the specimen cross-section <14ram time. to the laser process, using the spectrometer with a small jig (<14ram) while working curve drawing tool, as the sample preparation depending on the sample matrix, for iron, cobalt, nickel particle size of the matrix 4ox60 A1. 0 circular grinding wheel on the preparation, the other the matrix with tungsten carbide lathe or milling machine tool preparation, if required in the determination of the matrix trace elements, then the system must be like lathes or milling machines to improve the accuracy of two methods of test accuracy is a measure of precision of a method and apparatus of the key indicators. Analysis of the experimental precision of the method described. is the use of nickel based analysis of standard samples of 35 tested, and in the strict precision of the method is best used when the test sample or control sample spacious production control analysis methods to more accurately reflect the degree of precision. 3. measuring range of the control to draw the nickel working curve based alloy samples is a reflection of the work within a certain concentration curve, beyond the scope of this curve can not use this work curve in the actual analysis process, all ingredients of change, and in high purity nickel (Ni content of 99.99 above) may be most of the trace impurity elements is, in this case can be made in accordance with the method developed low levels or high levels of working curve, in order to achieve the purpose of Determination.
