ABSTRACT:
The invention relates to a flow cell, a method for separating carrier-free radionuclides from a liquid or liquefiable target material, and the radiochemical reaction thereof. According to prior art, flow cells are known which require reaction volumes corresponding to the volume of the target material in order to carry out the desired reactions. The inventive flow cell (1) and method enable the reaction volume, and thus the quantity of starting material, to be reduced by a multiple by reducing the cylinder volume (=reaction volume). As the radioactively marked product is present in very small quantities (picomole to nanomole), the HPL-chromatographic separation of the non-reacted starting material is significantly improved. The economic efficiency of the method is increased due to the fact that small quantities of starting material can be used.
