    Abstract

    It is possible to apply the k(0)-method using a simplified equation for concentration calculations using Excel spreadsheet, using comparators without making corrections. The objective of this study was to confirm that the k(0)-standardization method is more efficient and accurate than this "k(0)-comparator" procedure, applying suitable software that takes into account several corrections. The reference material GBW07401 soil was analyzed in this study. Relative Bias and u-score tests were used in order to evaluate the overall results.
