When more than one person qualifies to do the sarre <br />test, replicate data will be compiled to validate not only <br />personnel but also the method of analysis used. Personnt' <br />demonstrate their proficiency in conducting chemical analyses by <br />analy`ing spiked standard samples prior to conducting analyses of <br />natural samples. They will be prepared by spiking dei onized water <br />with the analyte of interest at: <br />0.0 times the desired detection limit. <br />-0.5 times the desired detection limit. <br />1.0 times the desired detection limit. <br />2.0 times the desired detection limit. <br />5.0 times the desired detection limit. <br />10.0 times the desired detection limit. <br />Detection limits are calculated using the method in Section 13.0. <br />- -- - The accuracy is the slope of the best linear regression line of <br />found versus target concentration. The best linear fit regression <br />line must have a correlation coefficient of 0.996 for the <br />calculation of the detection limit and accuracy. A minimum of one <br />sample at each concentration level is analyzed each day for three <br />separate days. The precision of the method is the standard error <br />of the best fit linear regression line of the found versus tercet <br />
