Orthophosphate, Pyrophosphate, Trimetaphosphate, and Tripolyphosphate in Shrimps Applying a Dose-in Gradient

This application note describes the determination of orthophosphate and polyphosphates in shrimp meat using the 930 Compact IC Flex. The Dose-in Gradient setup allows to speed-up phosphate separation by adding a stronger eluent during the run. The separation is achieved by increasing the carbonate concentration while keeping hydroxide constant.
