Description

Highlights: • Online Pu measurement system coupling α-LSC with microchip was developed. • Flow-through cell of α-LSC was prepared to combine microchip outlet. • A stable two-phase flow was formed in microchannel with the use of coiled tube. • Analytical performance of the system was characterized. - Abstract: An online measurement system using an alpha liquid scintillation counter (α-LSC) coupled to microchip solvent extraction has been developed. A flow-through cell of α-LSC has been prepared by packing PTFE tube into glass tube to combine microchip. Two-phase flow in microchannel has been stabilized by using coiled tube. The Pu in organic phase has been mixed with scintillation cocktail by T-junction connectors. The system separates and detects Pu by online with detection limit of 6.5 Bq/mL, generating only μL-level wastes.
