Analysis Name |
Dynamic Mechanical Analyzer (DMA) |
|
Device Brand and Model |
PERKİN ELMER & 7100 |
|
General Information |
DMA are analytical instruments that determine the physical properties of a wide range of materials such as polymer solutions, composites and solids. Physical properties of these materials are strength, tension, strain, frequency and temperature values. While the materials are deformed by the applied mechanical stress, the energy loss properties are determined by measuring the values in the displacement according to the applied force. Analyzer records temperature-dependent visco-elastic properties and determines the modulus of elasticity and damping coefficient by applying an oscillating force to the sample. DMA mainly differs from other mechanical devices in two ways. First, the tensile testers focus solely on elastic particles. Second, tensile testers operate outside of the linear viscoelastic range. DMA works within the viscoelastic range and is also more sensitive to samples' structures. |
|
Sample Preparation |
For DMA Analysis, the desired thickness, width and length of the samples must be prepared by the researchers. |
|
Usage Area |
Materials such as polymers, polymer blends, elastomers, composites, fibers, films, and resins can be tested with DMA. |

Device Name |
Thermogravimetric - Differential Thermal Analyzer (TG / DTA) |
|
Device Brand and Model |
HITACHI & 7300 |
|
General Information |
Thermogravimetric analysis (TGA), is the method in which the change in sample mass is examined as a function of temperature or time in a controlled atmosphere (in an environment where the temperature is increased programmatically). The temperature of the sample is subtracted from the temperature of the reference and this difference is plotted against increasing temperature. The peaks seen here can be endothermic or exothermic. |
|
Sample Preparation |
It is necessary to consider many factors in sample preparation for TG-DTA experiments. These; the sample must have all the properties of the material to be analyzed. The mass of the sample should be sufficient for the test. The sample should be able to change very little during the sample preparation phase. No contamination should occur in the sample during the sample preparation phase. The morphology of the sample affects the diffusion value of the reaction result and the order of the reaction course. However, it can also affect the heat transfer within the sample. The mass used in the experiment can affect the mass loss rates during the heat transfer process and similar diffusions. |
|
Usage Area |
Applications such as transformation, evaporation, sublimation, decomposition, decarbonation, dihydroxylation, dehydration, combustion products of organic materials, coal, oil and fuels, oxidation of metals, reduction, sintering, corrosion, decomposition of polymers can be performed with the TGA / DTA device. With TGA, the resistance of chemical and natural fiber-based textile materials (fiber, yarn, fabric) to heat and flame can be tested for quality control purposes. DTA determines melting, boiling and disintegration points with high accuracy. It also provides information about crystallization and phase changes.
