Al-Metyaf: a Smart Phone Application for Colorimetric Analysis

Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent. This poster explores the utilization of smartphones for colorimetric quantification of biological macromolecules. A low-cost optomechanical device and an Android application were designed to capture the image of a substance sample, and detect its concentration using the Saturation channel from the HSV color space. We report the device design and findings from preliminary experiments.
