WebPerkinElmer Thermogravimetric analysis (TGA) is conducted on an instrument referred to as a thermogravimetric analyzer. A thermogravimetric analyzer continuously measures mass while the temperature of a sample is changed over time. Mass, temperature, and time are considered base measurements in thermogravimetric analysis while many additional measures may be derived from these three base measurements.

WebThe TGA thermogram consisted of a gradual weight loss starting at about 70°C. The thermogram demonstrated that sublimation of mirtazapine base started at 70°C (confirmed by hot stage microscopy) and the sudden drop in TGA curve at 120°C corresponds to the thermal decomposition of mirtazapine that takes place during the melting process ( Fig. 3 ).
