The color contributes a major portion of the appearance and hence it is essential to ensure that the color of the products is of the best quality and level. To ensure that, a colorimeter is used. A colorimeter is a light-sensitive device used for measuring the transmittance and absorbance of light passing through a liquid sample. The device measures the intensity or concentration of the color that develops upon introducing a specific reagent into a solution.

Before reaching the solution the ray of light passes through a series of different lenses. These lenses are used for navigation of the colored light in the colorimeter. The colorimeter analyzes the reflected light and compares it with a predetermined standard. Then a microprocessor installed in the device is used for the calculation of the absorbance of the light by the solution. If the absorption of the solution is higher then there will be more light absorbed by the solution and if the concentration of the solution is low then more lights will be transmitted through the solution.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The colorimeter is based on Beer-Lambert&#8217;s law, according to which the absorption of light transmitted through the medium is directly proportional to the medium concentration.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As mentioned earlier, the colorimeter is based on Beer-Lambert&#8217;s law, according to which the absorption of light transmitted through the medium is directly proportional to the medium concentration.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">The mathematical representation of the combined form of Beer-Lambert\u2019s law is as follows:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Log<\/span><span style=\"font-weight: 400;\">10<\/span><span style=\"font-weight: 400;\"> I<\/span><span style=\"font-weight: 400;\">0<\/span><span style=\"font-weight: 400;\"> \/ I<\/span><span style=\"font-weight: 400;\">t<\/span><span style=\"font-weight: 400;\"> = a<\/span><span style=\"font-weight: 400;\">s<\/span><span style=\"font-weight: 400;\">bc<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If b is kept constant by applying Cuvette or standard cell then,<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Log<\/span><span style=\"font-weight: 400;\">10<\/span><span style=\"font-weight: 400;\"> I<\/span><span style=\"font-weight: 400;\">0<\/span><span style=\"font-weight: 400;\">\/I<\/span><span style=\"font-weight: 400;\">t<\/span><span style=\"font-weight: 400;\"> = a<\/span><span style=\"font-weight: 400;\">s<\/span><span style=\"font-weight: 400;\">c<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The absorbency index\u00a0 as is defined as<\/span><\/p>\n<p><span style=\"font-weight: 400;\">a<\/span><span style=\"font-weight: 400;\">s<\/span><span style=\"font-weight: 400;\"> = A\/cl<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Where,<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0c = <\/span><span style=\"font-weight: 400;\">concentration of the absorbing material (in gm\/liter).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0l = <\/span><span style=\"font-weight: 400;\">distance traveled by the light in solution (in cm).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In simplified form, the Beer-Lamberts law is commonly written as:<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">A= \u0190cl<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400;\">Where A is the absorbance (no units, since A = log10 P0 \/ P ), \u0190 is the molar absorptivity (with units of L mol-1 cm-1), c is the concentration of the compound in solution (expressed in mol L-1) and l is the length that the light passes through (expressed in centimeters).\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Note that if there is a continual changing of the solution, then the percentage of transmittance against time is generally used.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">To measure concentrations, the amount of light absorbed is dependent upon the amount of solute.
