Abstract. Chip-based fast scanning calorimetry (FSC) or chip-calorimetry based on MEMS-sensor technology nowadays enables constant heating and cooling rates from 10 2 up to more than 10 9 K/min on micro- to nanogram samples, respectively, as measured between − 150 and 1000 °C. Evidently, fast processes – like applied in production during cooling – can now be .
