Irudi Digitalen Analisia: espektrofotometroa ordezkatzen

Abstract

Digital Image Analysis (DIA) consists of a set of techniques that aim to obtain representative information about a system using images of that system. The main advantages of this method are its speed, simplicity and small amount of sample needed (below 400 μL if microplates are used), as well as the small amount of waste created. Three different applications are described for DIA in this work: the determination of some of the major compounds in a nickel electroplating baths, such as nickel, ammonium and sulfate ions; the simultaneous determination of phosphates and pH in different eye drops and the simultaneous determination of the color additives tartrazine and allura red in food products. In these applications, a flatbed scanner and a smartphone were used for image acquisition.
