AMBIENT PERTURBATION REDUCTION IN MICROSIZED CALORIMETRIC SYSTEMS

To avoid thermostatting effort in a calorimeter the influence of ambie nt temperature perturbations on the output signal can be reduced by pr edicting and correcting the perturbation part of the output signal of the calorimeter. The prediction can be verified by measuring the tempe rature perturbations and simulating the corresponding output signal. U sing a dynamical model of the calorimeter, simple methods for the solu tion of this problem are shown and tested experimentally. (C) 1997 Els evier Science B.V.
