TGA DTA Phase diagrams & Thermal analysis • Thermal analysis,an experimental method to determine phase diagrams. This technique, termed MTDSC or MDSC, applies a sinusoidal temperature modulation superimposed over a linear heating rate. There are two types: Heat-Flux DSC and Power Compensating (true) DSC. These instruments are sometimes called heat flux DSCs. Differential Scanning Calorimetry (DSC) is the most popular measurement thechnique to detect endothermic and exothermic transitions like the determination of transformation temperatures and enthalpy of solids and liquids as a function of temperature. It is widely used in industrial settings as a quality control instrument due to its applicability in evaluating sample purity and for studying polymer curing.

Spinal instrumentation techniques have expanded dramatically over the last decade. 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 DSC is used to measure enthalpy changes due to changes in the physical and chemical properties of a material as a function of temperature or time. The standard recognizes these needs, when they are consistent with the objectives of the standard, by providing alternative symbolism methods. Our DSC solutions are simple and offer high accuracy and precision, from very low to very high temperatures. Gramaglia D(1), Conway BR, Kett VL, Malcolm RK, Batchelor HK.
