Modular structures with interchangeable sensors or measurement modules. Simplified descendant of the original power compensation DSC, and a close relative to DTA (differential thermal analysis) instruments, this DSC is adequate for a measurement of accurate temperature range of a thermal transition. DSC can only be used with non-corrosive samples, meaning that any material that contains any halogen moieties (F, Cl, Br, I etc) cannot be used. The DSC is capable of heating samples to 600°C. A second crucible without sample was used as a reference. instrumentation systems used for measurement and control. Differential scanning calorimetry (DSC): heat difference Pressurized TGA (PTGA): mass changes as function of pressure. A — HUMAN NECESSITIES; A61 — MEDICAL OR VETERINARY SCIENCE; HYGIENE; A61F — FILTERS IMPLANTABLE INTO BLOOD … Better sensitivity means that it is possible to detect smaller thermal effects in the sample or conversely to use smaller amounts of sample. 200 K/min The test conditions are perfectly identical for the TGA and DSC signals (same atmosphere, gas flow rate, vapor pressure of the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). This technique can be used for both substances and chemical reactions. Copyright © 2020 Elsevier B.V. or its licensors or contributors.

Thermo mechanical analysis (TMA): deformations and dimension Dilatometry (DIL): volume Evolved gas analysis (EGA): gaseous decomposition products Often different properties may be measured at the same time: TGA-DTA, TGA-EGA The reference chamber is filled with a solvent. An example of DSC analysis: A small amount of sample (1-15 mg) was contained within a closed crucible and placed into a temperature-controlled DSC cell. Differential scanning calorimetry (DSC) is an instrument that measures the heat capacity of small material samples called thermoanalytical technique. This is accomplished by measuring temperature differences and changes between a sample and a refer- ence, or the heat flux. Dsc presentation 1.
