A radionuclide separation Sample Preparation
A range of products that employ the technique of radionuclide separation to efficiently preconcentrate and separate radionuclides from a variety of different matrices have recently been introduced by Eichrom Technologies LLD (Lisle, Illinois, USA) and Triskem International (Bruz, France). Extraction chromatography combines the power and selectivity of solvent extraction with the ease of use of a chromatographic column. Through careful selection of the extractant, which is adsorbed onto the resin support, a material is produced that is highly specific for a particular radionuclide or group of radionuclides. In the majority of cases, either retention or elution of the radionuclide of interest is achieved by modification of the concentration of the acidic eluent used. Employing such technology has resulted in an accurate and reproducible sample preparation method for the determination of radionuclides in environmental samples.
