This paper describes the use of IBC′s AnaLig®Pu-02 molecular recognition technology product to effectively and selectively pre-concentrate, separate and recover plutonium from urine samples. This method uses two-stage column separations consisting of two different commercial products, Eichrom’s Pre-filter Material and AnaLig®Pu-02 resin from IBC Advanced Technologies. By eliminating the co-precipitation techniques and the ashing steps to remove residual organics, the analysis time was reduced significantly. The method was successfully tested by adding known activities of reference solutions of 242Pu and 239Pu to urine samples.

A rapid separation method has been developed which allows measurement of plutonium, americium and strontium isotopes in the high active sample from CBRN Training and Testing Centre in Zemianske Kostolany (Slovakia) with high chemical recoveries and effective removal of matrix interferences. This method uses different commercial products stacked AnaLig® Pu-02, AnaLig® Sr-01 and DGA® Resin cartridges from IBC Advanced Technologies and Eichrom Technologies. The method allows rapid separation of plutonium, strontium and americium using a single multi-stage column in the vacuum box (cartridge technology) with rapid flow rates to minimize sample separation time. The 239,240Pu, 238Pu and 241Am were determined by alpha spectroscopy, 90Sr was counted on TRICARB 2900 TR by Cerenkov counting of its progeny 90Y.

In this paper three different methods were used for plutonium separation and statistical tested-molecular recognition technology products AnaLig® Pu-02, liquid–liquid extraction with Aliquat-336 and extraction chromatography with TRU® Resin. The methods performance was investigated by analysis of NPL (High Alpha–Beta 2005) intercomparison sample. Regression diagnostics procedures were used for examination of the regression triplet and pair t test were applied for comparison of methods for the separation of 239,240Pu, 238Pu with Aliquat-336, TRU® Resin and AnaLig® Pu-02. The presented results were evaluated as correct for all experimental data.
