title: High accuracy, self-calibrating photopyroelectric device for the absolute determination of thermal conductivity and thermal effusivity of liquids.
abstract: An improved photopyroelectric approach to simultaneously determine the thermal conductivity and thermal effusivity of minute quantities of liquids, which is based on a combined scan of the modulation frequency and the piston-sensor distance, is presented. A thorough sensitivity analysis and statistical analysis of the fitting uncertainties show that the method is a very accurate tool for the simultaneous determination of the thermal conductivity and thermal effusivity of liquid samples.
