Dsc q200 ta instrument

For DSC about 2 mg of each sample was placed in an aluminium pan and heated at a rate of 10 °C per minute till 300 °C. Nitrogen gas was purged at a rate of 50 mL/minute. A DSC Q200-TA instrument (TA Instruments, New Castle, DE, USA) was used for the analysis.

TGA measurements (TA Instruments, New Castle, UK) were performed over a temperature range of 30–350 °C under a 50 mL·min⁻¹ N₂ flow, on a Q600 SDT TA instrument equipped with a DSC heat flow analyzer. Samples (5–10 mg of weight) were placed into the furnace inside alumina crucibles and heated with a ramp of 10°C·min⁻¹. DSC curves were collected on a DSC Q200 TA Instrument (TA Instruments, New Castle, UK). Samples were accurately weighed (5–10 mg) and put into sealed aluminum pans. Calibration for temperature and heat flow was performed using high purity standards of n-decane, benzene and indium. All measurements were performed in a 30–350 °C temperature range, with heating rates of 10 °C·min⁻¹.
