what is thermal analysis technique in pharma

-Thermal analysis comprises a group of techniques in which a physical property of a substance is measured as a function of temperature, while the substance is subjected to a controlled temperature programme.           

-Enthalpy, weight, dimension, heat capacity, electric conductivity, gas evolution etc are some physical properties examined by thermo analytical techniques. 

-Furthermore they provide information on crystal perfection, polymorphism, melting temperature, sublimation, glass transitions, dehydration, evaporation, pyrolysis, solid-solid interaction and purity, Such data are useful in the characterization of substance with respect to compatibility, stability, packaging and quality control.
