Abstract
Two samples of one litre each of mercury contaminated soil were analyzed by Big Sample INAA. Using this method, sample preparation procedures can be omitted and the number of sample size reduction steps are decreased. Therefore, the representativity of the sample is improved. Afterwards, Big Sample INAA is compared to standard INAA by analyzing ten subsamples taken from each one litre sample. It is concluded that multi-element analysis results of Big Sample INAA are valid even for inhomogeneous large samples. This paper presents the first concentrations measured with BSINAA.
