| Abstract: | A method for the rapid quantitative determination of impurities in ultra-pure organic compounds is described. It is based on the difference in slopes of the curves obtained when the difference in temperature between the sample and a reference shield is plotted against time. The results are compared with those obtained by thermal analysis. |
