Abstrakt

The method of the direct determination of Cu and Zn by ICP-MS in the whole human blood 1:9 diluted with Triton X-100 and HNO3 (0.1 % Triton X-100 and 0.2 % HNO3 in the final solution) was compared with the method based on blood decomposition in a microwave apparatus. Correlation coefficients between both methods were 0.965 and 0.988 for Cu and Zn, respectively (n - 12). The relative standard deviation of repeatability was about 2 % for both methods and metals. The direct analysis without sample decomposition is recommended.
