A novel dual-valve sequential injection manifold (DV-SIA) for automated liquid-liquid extraction. Application for the determination of picric acid

Abstract

Novel DV-SIA manifold that resolves the main problems of LLE utilization in SIA has been designed. The main idea was to construct SIA system connecting two independent units, one for aqueous-organic mixture and the second for organic phase flow.
