Electrochemical and optical sensing of polyions were first introduced in the early to mid 1990s via the development and study of the first heparin-sensitive potentiometric and optical polyion sensors. Since then, the number of reports relating to electrochemical and optical polyion sensing technologies have grown substantially. Both biologically and industrially relevant polyions can be detected using...
Potentiometric polyion‐sensitive polymeric membrane electrodes are capable of detecting a wide variety of polyionic macromolecules. Herein, we utilize this lack of selectivity to report the first application of this sensor technology as a detector in liquid chromatography (LC). A reversible polycation pulstrode based on tridodecylmethylammonium‐dinonylnaphthalene sulfonate doped within a polymeric...
