The DSCsignal is generally generated by heating a dish containing a sample and an empty reference dish using the same heat source.
If you subtract the heat flux signals of the two shells from each other, you get endothermic or exothermic peakswhen the sample temperature changes due to thermal effects.
The Chip-DSC integrates all the essential components of a DSC—the oven, sensor, and electronics—into a miniaturized housing.
The chip assembly incorporates the heater and the temperature sensor into a chemically inert ceramic assembly containing a metallic heater and a temperature sensor.
As a result, the chip DSC enables very fast heating and cooling rates while maintaining high resolution, accuracy, and reproducibility.
In this example, skim milk powder was analyzed using DSC in the temperature range from -0 to +85 °C. Skim milk powder contains approximately 50% lactose (“milk sugar”), 36% protein, and 4% residual water.
Due to the manufacturing process, the lactose is amorphous (“glass-like”) and has a glass transition temperature above room temperature. This glass transition was investigated at various heating rates.
