A solution containing two different fluorescent compounds, Ben and Jerry, were analyzed for their individual concentrations in the mixture. Standards of pure Ben and pure Jerry were prepared at a concentration of 500.0 mM and were run in a UV-Vis Spectrophotometer to determine their absorption properties Absorbance Wavelength Compound Ben 500 mM Compound Jerry 500 mM 400 nm 0.137 0.136 450 nm 0.312 0.113 500 nm 0.154 0.078 550 nm 0.076 0.079 600 nm 0 227 0.148 650 nm 0230 0230 700 nm 0.151 0.357 750 nm 0.157 0246 800 nm 0.154 0.154 A standard curve of the standards was also prepared to help determine the concentration of each component in the solution. The solution produced an absorbance reading of 0.486 at the Amax of Ben, and 0.463 at the Amax of Jerry.
