An apparatus utilizes optical reflectivity (REF) to measure concentrations in liquids. The REF optical system is packaged in a compact and cost-effective form factor. An electronic circuit drives the optical system. The miniaturized REF sensor is situated in an optical-fluidic cell or an optical-fluidic...http://www.google.fr/patents/US7268864?utm_source=gb-gplus-shareBrevet US7268864 - Method for a liquid chemical concentration analysis system
