Include all details on preparation of standard solutions. Also include the vitamin tablet brand name; the listed mass of vitamin B2 per tablet; procedure used for extraction of the tablet and dilutions performed. The experiment began by determining the best wavelength at which to excite the riboflavin molecule, by examining the graph given in the laboratory manual. To measure this, a few drops of the stock 50ppb solution was pipetted into the plastic cell and the fluorescence machine was calibrated using the settings in the laboratory manual.
