An Detection Method of Substance Concentration

Colorimetry is a commonly used method to detect the concentration of substances. Because of the sensitive difference and observation error of each person to color, the accuracy of this method is greatly affected. With the help of photographic technology and the improvement of color resolution, the quantitative relationship between color value and substance concentration is established, and the model error is analyzed. Meanwhile, some criteria are also given to evaluate the advantages and disadvantages of the data. At the end of the paper, the influence of color dimension on the model is discussed. This method provides a simple and reliable method for the analysis of solution concentration by colorimetry and a basis for the automatic quantitative analysis of colorimetry.
