ChemEye is used to turn your mobile device as a detector and readout device for colorimetric measurement. Colorimetry is a technique in analytical chemistry that is applied to measure the amount of colored compounds in solution, such as heavy metals, sugars, proteins, food additives, and environmental pollutants. The use of ChemEye would replicate the function of a spectrometer with comparable accuracy, sensitivity and repeatability. This app is designed to enable you to: - Understand the basic principles and theory of colorimetry; - Solve real-life analytical science problem; - Perform detection anytime and anywhere; and - Learn outside the laboratory.
