ABSTRACT:
A vented filter is placed at the HPLC (High Performance Liquid Chromatography) loop entry port of an HPLC injector valve. The vented filter prevents the push gas used to deliver the crude radiolabeled product from over-pushing the liquid to waste. Push gas is vented off when the entire crude liquid product has passed through the vented filter and been loaded onto the HPLC loop.
