Method of measuring the concentration of chemical epecies

Method of measuring the concentration of chemical species of industrial, environmental and biomedical interest through the processing of the RGB values ​​of a digital photograph taken together to a colorimetric sensor and a system of reference patterns. It enables a user unskilled with a device with any type of camera capable of data processing, perform the analysis of any chemical species of interest, for example blood iron. removal of ambient noise is made possible, enabling the correct analysis from the chemical point of view from a photograph taken under all light conditions and with any type of camera. Equally important it is that the device used is commercial and requires no adaptation, only the algorithm executes the process of extracting the data from the back photography and analysis.
