Separate Alkali Metals & Alkaline Earths Rapidly On Short Columns Use BIO-RAD Ion Exchange Crystals Bio-Rad 2 M (zirconium tungstate) 0.13 cm1 χ 12.3 cm column, 0.75 cm/min. flow rate, trace loading.
Illustrated is an alkali metals separation which can be effected on any one of these new in organic exchangers. Adsorption usually takes place from acidic solutions. Increasing con centrations of ammonium chloride or nitrate are used for elution. Bio-Rad Ion Exchange Crystals are inorganic microcrystalline aggregates with ion exchange capacities and properties similar to those of conventional ion exchange resins, but whose deferences oiler special advantages including the ability to perform separations at temperatures up to 300° C and to withstand high level radiation without breakdown. High selectivity for specific ions allows chromatographic analysis of trace materials in concentrated solutions. Separations of precious metals, cesium from brines, polyvalent anion;, and reactor fission products are described in "Ion Exchange Crystals"—check below.
