Introduction

Keith A Friedman is a notable inventor based in Santa Clara, CA (US). He has made significant contributions to the field of ion chromatography, holding a total of 3 patents. His work focuses on improving the efficiency and cost-effectiveness of ion chromatography systems.

Latest Patents

One of his latest patents is an "Ion chromatography system using electrochemical suppression and detector." This invention discloses a method for streamlining and lowering the operational costs of ion chromatography while enhancing detection limits. The apparatus features chromatographic separating means that allow a sample to be eluted in an eluent solution containing an electrolyte. It includes suppressor means with a chromatography effluent compartment separated from a detector effluent compartment by an ion exchange membrane. This design creates distinct flow channels for both the chromatography effluent and the detector effluent. Electrode means are integrated into both flow channels to pass an electric current transverse to the solution. The chromatography effluent flows through the suppressor and is detected by means that identify resolved ionic species. The effluent from the detector is recycled through the detector effluent flow channel, forming a sump for electrolyte ions and supplying water for the electrolysis reaction that generates acid or base for suppression.
