  • Patent number: 6146013
    Abstract: A method and apparatus for performing combined single differential thermal analysis and dynamic mechanical analysis of a sample relative to a reference, using either one reference measurement for a sequence of material measurements--whereby the reference can also be represented by an empty weighing pan--or by the use of a mathematical model which is so determined that it takes the real behavior of the thermal analytical apparatus into account. Reference temperature curves are generated relative to time of an empty furnace or a reference sample contained in the furnace, and temperature curves of a sample to be measured are taken at the exact same location in the furnace. The reference and sample temperature curves are compared to determine the temperature difference.
    Type: Grant
