project description
Spectrophotometers utilize a range of select wavelengths that allow them to detect the presence of certain chemicals, compounds, or elements dissolved in aqueous solutions that we will refer to as impurities. Spectrophotometers exploit the absorption and transmission profiles of such impurities to show a distinct difference in the intensity of the incident light versus the received light, after passing through a sample containing the impurity. We developed a system that engages this concept to detect Chlorophyll A and Chlorophyll B impurities present in a water sample. The primary physical property that will be used to determine the presence and quantities of chlorophyll impurities will be the Lambert-Beer Law, which highlights the ability to calculate the concentration of a substance when both input and output intensities are known in adjunction with the chemical absorption coefficient. The design’s ability to detect chlorophyll concentrations will allow users to detect the amount of photosynthetic material present in just about any organic material. Indicators of photosynthetic capabilities can be used to better understand organic materials and their macroscale impact on surrounding environments.
