Abstract

We present an analytical approach for the detection of perfluorooctane sulfonate (PFOS) by ion transfer stripping voltammetry at an array of micro-interfaces between two immiscible electrolyte solutions. With this approach, picomolar concentrations are detected and environmental matrix effects are evaluated.
