Orthophosphate, pyrophosphate, trimetaphosphate, and tripolyphosphate in shrimp applying a Dose-in Gradient

The determination of orthophosphate and polyphosphates is an important quality control for shrimp. The Dose-in Gradient setup accelerates phosphate separation by adding a stronger eluent. The separation of the phosphates is achieved by increasing the carbonate concentration while maintaining the same hydroxide content.
