We mainly use standard ion exchange techniques to purify various target elements from sample matrices. The ion chromatographic separations are performed in hand-made Teflon columns of various sizes. Placing the columns in our in-house built carousels simplifies the handling and allows the simultaneous separation of up to 24 samples.
The ion exchange techniques presently used at the BGF include:
听听听 - Rb-Sr-REE separation using standard cation exchange chromatography (DOWEX AG-50)
听听听 - Sm-Nd purification with Eichrom Ln-resin
听听听 - Rb-Sr separation from carbonates using Eichrom Sr-Spec resin
听听听 - U and Pb separation with standard anion exchange (DOWEX AG-1x8) and Eichrom Sr-Spec resins
听听听 - Cu, Fe, Zn separation on a single column filled with AG MP-1 anion resin
听听听 - Cr purification with anion resin (DOWEX AG-1x8) and liquid-liquid extraction
听听听 - Pa separation on anion exchange resin
听听听 - Li chromatographic purification on cation exchange resin
