The supposition of even temperature distribution in the sample mass (‘ingradient’ approach) led to mathematical expressions describing the basic quantitative elements of thermal curves: the transformation duration, the peak height, the initial and final section peak areas and the total area. The simplest expression is that for the total peak area: S=(R2Hd/2k1)1nR1/R, where R, H, d, k1and R1are the...
