Thus, the range of application can be extended beyond the threshold of impurity of 5 mol%.
determination of purity using the VAN'T HOFF equation without a mathematical approximation.The following features set this program apart from the known solutions as well as from ASTM E 928: Purity Determination is a program for determining the purity of a material through analysis of the DSC melting peak. The DSC melting peak is evaluated for each. sintering steps (DIL, TMA) ‒ and to calculate activation energy(ies) from a measurement (TGA).įor crystalline substances with known molar mass, Purity Determination serves to determine the percentage of eutectic impurities on the basis of the Van ’t Hoff equation. relaxation peaks (DSC) or thermal expansions and Sintering Sintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. The process responsible for stress relaxation can be physical or chemical, and under normal conditions, both will occur at the same time. This makes it possible to deconstruct the signals into reversing and non-reversing parts (DSC, DIL, TMA) and thereby separate overlapping effects ‒ for example, glass transitions and Relaxation When a constant strain is applied to a rubber compound, the force necessary to maintain that strain is not constant but decreases with time this behavior is known as stress relaxation. When applying temperature modulation, which is available for the TG 209 F1 Libra ®, TG 209 F3 Tarsus ®, DSC 214 Polyma, DSC 204 F1 Phoenix ®, DSC 3500 Sirius, DSC 404 F1 Pegasus ®, STA 449 F1 Jupiter ® (TM-DSC), STA 449 F3 Jupiter ® (TM-DSC), DIL 402 Expedis Select, DIL 402 Expedis Supreme and TMA 402 F1 Hyperion ® (for TMA and DIL, beginning with the 7 th generation of the Proteus ® software), the linear heating rate is superimposed by a sinusoidal temperature change. For comparison purposes, any measurement curves can even be superimposed onto each other – even those of differing types. The various hits on the list can be integrated into the evaluation graphs with a single click of the mouse.
When using Identify, a hit list is produced – of the type known, for example, in spectroscopy. The NETZSCH libraries supplied include more than 1,300 entries from the application fields of polymers, organics, food, pharma, metals/alloys, ceramics and inorganics, as well as the chemical elements. With a single click, experimental curves (even ones that are not yet evaluated) can thus be checked for agreement with stored individual curves, literature data or statistical classes. Via database comparisons, it only takes a few seconds for Identify to identify and classify materials. The specific heat capacity is related to a unit mass of the specimen.cp curves).

In the field of thermal analysis, Identify is the only software of its kind (beginning with Proteus ®® version 7.1 applicable to DSC, TGA, DIL, TMA and Specific Heat Capacity (cp) Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase.
