Differential thermal analysis under quasi-isothermal, quasi-isobaric conditions (Q-DTA)

For testing this new method, CuSO4·5H2O, MnSO4·5H2O, Mg(NO3)2·6H2O and Na2SO4·10H2O have been investigated. These model substances can be prepared in stoichiometric composition free of impurities, their decomposition mechanism is well-known, thus the effect of the altered experimental conditions by the simultaneous Q-DTA, Q-TG method on the course of their dehydration can be calculated.
