A computer facilitated, interactive method of requesting an spectrographic analysis of a sample having an unknown concentration or purity, performing an energy absorbance analysis of the sample to obtain spectrographic data regarding the analysis and comparing the spectrographic data to a stored spectrographic data regarding the analyses of the samples having a predetermined concentration and purity to determine the concentration or purity of the sample having an unknown concentration or purity. The requester can electronically request the analysis and monitor the progress of the analysis. The results of the analysis are electronically transmitted to the requester in real time.
