Popis: This method uses stacked column separations consisting of different commercial products pre-filter material, DGA® Resin from Eichrom Technologies and AnaLig® Pu-02 gel, AnaLig® Sr-01 gel from IBC Advanced Technologies. Raw urine was acidified and passed directly through the resin columns. The method was successfully tested by adding of National Physical Laboratory (NPL) Alpha–Beta High 2005 sample with known activities of radionucledes to urine samples. The demonstrated linear model clearly proves that the residua fulfill the Gaussian model, without any autocorrelation and trend for intercomparison NPL Alpha–Beta High 2005 sample. By eliminating the co-precipitation techniques and the ashing steps to remove residual organics, the analysis time was reduced significantly.
