Fast chip calorimeters

Mathot, V, Pyda, M., Pijpers, T., Vanden Poel, G., van de Kerkhof, E., van Herwaarden, S., van Herwaarden, F., and Leenaers, A. (2011) The Flash DSC 1, a power compensation twin-type, chip-based fast scanning calorimeter (FSC) first findings on polymers. Thermochim. Acta, 522, 36-45. 

Fast DSC is based on the use of calorimeter chips. Samples are very small (about 100 times smaller than DSC samples). The scan rates are comparatively higher (typically 1 kK/s instead of 1 K/s). The measirrement is done in seconds instead of honrs. Very high heating and cooling rates are possible in this method. Hearing and cooling rate as high as 30,000 K/s were nsed. ... 

Differential scanning calorimetry (DSC) has proven to be a very reliable technique to obtain heat capacity at elevated temperatirres in a reasonably short time. DSC also allows the study of the kinetics of nonequilibrium transitions in a wide dynamic range. Because of its simplicity and ease of use, DSC is widely applied in polymer science and is the focus of this chapter. Recent additions such as temperature modulation and fast scanning, both making additional use of chip-based calorimeters, are also discussed in detail.
