Derivative thermogravimetric curve
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. WebMar 2, 2024 · Thermogravimetric (TG) and derivative thermogravimetric (DTG) curves for pure ground eggshells are plotted in Figure 3 and results are summarized in Table 3. Analyzing the TG/DTG curves presented in Figure 3 , it was observed that the thermal decomposition of ground eggshells and CaCO 3 proceeded similarly, although some …
