Project Objective
Measure properties of a zein film sample
- Thermal properties using DSC
- Viscoelastic properties using DMA
- Crystalline properties using XRD
Today's Task
Finish DSC Calibration
- Cell conditioning
- Measure sapphire heat capacity (baseline calibration)
- Determine cell constant (heat flow calibration)
- Measure melting point of Indium (temperature calibration)
Notes
- Cell conditioning: empty furnace, -80C to 300C (3 cycles)
- Baseline calibration: empty furnace, -80C to 300C at 20C/min (3 cycles) sapphire, -80C to 300C at 20C/min (3 cycles)
- Heat flow calibration: indium, 100C to 180C at 10C/min
- Temperature calibration: indium, 100C to 180C at 10C/min
Baseline Calibration successful.
