Discovery series dsc 25 dsc calorimeter

The thermal behaviors of the samples derived from the PETG/x wt.% Si₃N₄ composites and the pure PETG were examined by means of thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The apparatus used was a Diamond Perkin Elmer (Waltham, MA, USA) with a 40–550 °C temperature cycle at an increase rate of 10 °C/min. A Discovery Series DSC-25 DSC calorimeter (TA Instruments, New Castle, DE, USA) was used to obtain DSC measurements, along with an RSC-90 Refrigerated Cooling System. The TGA and DSC analyses were conducted in an inert environment in the presence of high-purity N₂ (nitrogen gas).

Thermogravimetric analysis (TGA) was performed along with differential scanning calorimetry (DSC) to obtain information on the thermal properties of the pure and nanocomposite samples. A Diamond Perkin Elmer device (Waltham, MA, USA) was employed for TGA analysis (40–550 °C temperature cycle, 10 °C/min temperature increase rate). DSC analysis was conducted using a Discovery Series DSC-25 DSC calorimeter (TA Instruments, New Castle, DE, USA). The device is equipped with an RSC-90 Refrigerated Cooling System (TA Instruments, New Castle, DE, USA). During both the TGA and DSC experiments, an inert environment and high-purity N₂ (nitrogen gas) were present.
