Many researchers in their articles use DTA instead of DTG what is the correct technique of each type?

Differential thermal analvsis (DTA). A technique of recording the difference in temperature between a substance and a reference material against either time or temperature as the two specimens are subjected to identical temperature regimes in an environment heated or cooled at a controlled rate.
Thermogravimetry (TG). A technique whereby the weight of a substance, in an environment heated or cooled at a controlled rate, is recorded as a function of time or temperature.
Derivative thermogravimetry (DTG). A technique yielding the first derivative of the thermogravimetric curve with respect to either time or temperature.
Differential thermal analvsis (DTA) is the first derivative of TGA ( mass loss function of temperature) , while DTG is the first derivative (mass loss function of time)
