Method and thermal analysis device including a sample holder and at least one temperature detector which is assigned to the holder. The invention further relates to a production method for a temperature detector. A heat flow to be detected is conveyed to the temperature detector between a support surface and the sample holder, wherein the support surface and/or the sample holder include elevations or depressions forming contact points, which define a relevant heat flow zone assigned to the support surface. A thermocouple, which includes at least two elements made of different metals, a first metallic element A, with a higher expansion coefficient compared to a second metallic element B, is introduced in a precisely fitting manner into second metallic element B constituted as a hollow profile and the two elements A, B are heated in a first operational step and then cooled again in a second operational step.

Method and device for material analysis

A system for measuring the thermal diffusivity of a material includes a housing having an upper portion and a lower portion, a plate holding the material in a fixed position between the upper portion and lower portion of the housing, and a source at the lower portion of the housing projecting heat onto the material along a first axis that is perpendicular to the plate. A sensor at the lower portion of the housing is movable in relation to the plate and senses the heat radiating through the material along a second axis that is perpendicular to the plate and offset from the first axis. A controller receives data from the sensor and calculates the thermal diffusivity of the material.

3D diffusivity

A method for evaluating a measurement result of a thermal analysis. A program-controlled computer unit is used to calculate at least one probability of the agreement of the measurement result with at least one dataset previously stored in the computer unit, wherein this calculation is based on a comparison of effect data previously extracted from a measurement curve of the thermal analysis with corresponding stored effect data of the dataset. The evaluation can advantageously include, an automatic recognition and classification of measurement curves and can be carried out in particular more efficiently, more economically and more quickly than previously, with at the same time a high quality of evaluation.

Method for evaluating a measurement result of a thermal analysis, as well as use of the method, computer unit, computer program product and system for performing the method

A method for conducting a differential thermal analysis, in which a sample disposed in a temperable sample space is tempered according to an essentially linear temperature program extending from a start temperature to an end temperature, such that, from the result of a measurement of the sample temperature conducted during tempering at a number of measurement time points, a DTA signal is calculated as the difference between a measured sample temperature and a reference temperature calculated according to a temperature curve model. According to the invention, for every measurement time point, the relevant reference temperature is calculated by the following steps: (a) establish a time interval containing the relevant measurement time point; (b) calculate a non-linear adjustment function for the measured sample temperature curve in the time interval; and (c) calculate the reference temperature as a value of the adjustment function for the measurement time point.
