WitrynaYou can create known percent solutions of the sample, take the IRs, create a linear plot (beers law) and derive the equation of the slope to understand the relationship between peak area and concentration. Then you can test your unknown to the calibration curve to find the percent concentration (units of ppm) and calculate the purity.
