isobaric mass-change determination

https://doi.org/10.1351/goldbook.I03261
A technique in which the equilibrium mass of a substance at constant @P04420@ of the volatile product(s) is measured as a function of temperature while the substance is subjected to a controlled temperature @P04869@. The record is the isobaric mass-change curve. The mass should be plotted on the ordinate decreasing downwards and temperature on the abscissa increasing from left to right.
