Abstract: A method for calibrating thermal resistance and thermal capacitance parameters characterizing a DSC cell, and then calculating the heat flow to the sample based upon the results of the calibration. The method is applied in a conventional heat flux calorimeter, to obtain thermal analysis data having improved baseline and resolution. A first embodiment is based upon a model of a calorimeter in which there is no cross-talk between the sample and reference sides of a DSC cell. The thermal resistance and thermal capacitance parameters are calculated by carrying out a sequential series of calibration measurements with an empty DSC cell, materials on the reference side and materials on both the sample and reference sides. Another embodiment takes the existence of cross-talk between the sample and reference sides of the calorimeter into account.

Abstract: A platinum/Rhodium resistance thermal probe is used as an active device which acts both as a highly localized heat source and as a detector to perform localized differential calorimetry, by thermally inducing and detecting events such as glass transitions, meltings, recystallizations and thermal decomposition within volumes of material estimated at a few .mu.m.sup.3. Furthermore, the probe is used to image variations in thermal conductivity and diffusivity, to perform depth profiling and sub-surface imaging. The maximum depth of the sample that is imaged is controlled by generating and detecting evanescent temperature waves in the sample.

Abstract: A system and method for performing localized mechanothermal analysis with scanning probe microscopy (“MASM”) is disclosed. In a preferred embodiment an image of the surface or subsurface of a sample is created. A localized region of the sample is selected from the image. Using a scanning microscope, an active or passive thermal probe is positioned at the selected region. A temperature ramp is applied to the localized region. In addition, a dynamic or modulated stress or strain is applied to the localized region. Force data resulting from the applied temperature and stress or strain is collected and processed to produce a graph or fingerprint of the dynamic mechanical and/or calorimetric properties of the selected localized region.

Abstract: A modulated differential scanning calorimeter that accounts for heat flow due to evaporative solvent loss. The calorimeter modulates the temperature applied to a sample and a reference to determine the amount of heat flow that is due to evaporation. By calculating the amount of heat flow due to evaporation, the user can determine how much of the heat flow of any given well is due to the process of interest as opposed to evaporation.
