This content is a preprint and has not undergone peer review at the time of posting.


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.
