Patent ID: 6935776

Claim:
A sample holder for differential thermal analysis, comprising: a substrate having a planar surface provided with a sample position for receiving a sample material and provided with a reference position for receiving a reference material; wherein the substrate is configured to allow a neat flow between a heat source to be thermally coupled to the sample holder and the sample position and the reference position; a first thermoelement arrangement in the area of the sample position and in the area of the reference position for supplying a first thermoelectric signal corresponding to a differential between a first temperature at the sample position and a second temperature at the reference position; first connectors formed on the substrate for connecting to the first thermal element arrangement; wherein the first thermoelectric signal corresponding to the differential between the first and second temperatures is tapped at the first connectors; a second thermoelement arrangement providing a second thermoelectric signal corresponding to an absolute temperature of at least one of the sample position and the reference position; second connectors provided on the substrate for connecting to the second thermal element arrangement; wherein the second thermoelectric signal corresponding to the absolute temperature is tapped at the second connectors; the first thermoelement arrangement has a row of first thermocontacts correlated with the sample position and the reference position, respectively; the first thermocontacts are composed of two different thermoelement materials and are connected serially to form a thermocolumn at the sample position and at the reference position, respectively; the first thermocontacts are alternatingly arranged on two circles of different radii centrally positioned relative to the sample position and the reference position, respectively; and the second thermoelement arrangement is a circularly delimited area of a first thermoelement material surrounded concentrically by a corresponding row of the first thermocontacts at least at one of the sample position and the reference position, wherein a connecting area extends from the first thermoelement material to one of the second connectors provided on the surface of the substrate.
