Differential Scanning Calorimetry (DSC)

       Differential scanning calorimetry (DSC) measures enthalpy changes in samples due to changes in their physical and chemical properties as a function of temperature or time.

Features and Benefits:


• Amazing sensitivity – for the measurement of weak effects

• Outstanding resolution – allows measurement of rapid changes and close-lying effects
• Efficient automation – most reliable 34-sample position sample robot for high sample throughput
• Small and large sample volumes – for microgram or inhomogeneous samples
• Modular concept – tailor-made solutions for current and future needs
• Flexible calibration and adjustment – guarantees accurate and precise measurement results under all conditions
• Wide temperature range – from –150 °C to 700 °C in one measurement
• Ergonomic design – intelligence, simplicity and safety facilitate your daily work

       The Differential Scanning Calorimeters (DSC) is used to measure the change of the Heat Flow of the sample when heated. Compared with the reference sample. The physical changes. And chemical composition of the sample was heated. Be related to the adsorption or desorption heat (endothermic or exothermic processes) or born of the heat capacity.

 

 

 

 

 

Thermogravimetry (TGA)

       Thermogravimetry (TGA) is a technique that measures the change in weight of a sample as it is heated, cooled or held at constant temperature.

Features and Benefits:


• High resolution – ultra-microgram resolution over the whole measurement range
• Efficient automation – most reliable sample robot for high sample throughput
• Wide measurement range – measure small and large sample masses and volumes
• Broad temperature scale – analyze samples from ambient to 1600 °C
• METTLER TOLEDO ultra-micro balance – rely on the balance technology leader
• DSC heat flow measurement – for simultaneous detection of thermal events
• Gastight cell – ensures a properly defined measurement environment
• Hyphenated techniques – evolved gas analysis using MS and FTIR
• Modular concept – tailor-made solutions for current and future needs

       Thermogravimetric Analysis (TGA) is used to analyze the thermal properties of an object to changes in temperature. By measuring the change in weight, weighing in at a high resolution and sensitivity. Environment in which the experimental set. To be used in the study, MA importance of various types of samples. The example in Ceramic, Polymer and inorganic substances can be analyzed for temperature, loss of weight, the impurities in the sample. Including the Phase analysis of the samples when heated.

 

 

 

 

 

 

Dynamic mechanical analysis (DMA)

       Dynamic mechanical analysis (DMA) is used to measure the mechanical and viscoelastic properties of materials as a function of temperature, time and frequency.

Features and Benefits:


• Dedicated force sensor and unique LVDT positioning for accurate measurement of moduli and tan δ
• Frequency range up to 1000 Hz
• Various deformation modes and measuring systems to accommodate any sample type and material suitable for DMA analysis
• Easy sample preparation using external mounting fixtures
• Traceable temperature calibration with melting point standards using SDTA
• Broad force and displacement range for measurements over stiffness ranges of 7 decades in one run

       Dynamic mechanical analysis (DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus. The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus; this approach can be used to locate the glass transition temperature of the material, as well as to identify transitions corresponding to other molecular motions.
