ASTM E698, E793, E794, E968, E1131, E1269, E1356, E1641, E2550 and others available Understanding the fundamental thermal transitions and stability is important for elucidating performance of a material. There are multiple methodologies which can be useful for determining these object and material characteristics, but none as accurate as calorimetric analysis. Differential scanning calorimetry (DSC) and differential thermal analysis (DTA) can be useful for determining fundamental thermodynamic properties of a material over specific temperature ranges, while thermogravimetric analysis (TGA) can provide insight into the stability of a material with respect to temperature. A variety physical properties can be measured through calorimetric measurements, including heat capacity (C p), glass transition temperatures (T g), enthalpy of transitions (ΔH), phase changes, solidus and liquidus points, and thermal stability. Below is a few methods which we can recommend for measuring these values. - Thermogravimetric Analysis (TGA) - Differential Scanning Calorimetry (DSC) - Differential Thermal Analysis (DTA) - Simultaneous Thermal Analysis (STA) – includes coupled TGA and DSC testing (TG-DSC) and coupled TGA and DTA testing (TG-DTA) - High sensitivity microcalorimetry with a 3-dimensional heat flow sensor (3D DSC) Thermal analysis and calorimetry see a very broad application. Anywhere thermodynamics or chemical stability can be a concern is a field where thermal analysis and calorimetry will see application. This includes, but is not limited to: - Cosmetics - Food science - Polymers - Materials Science - Metallurgy - Ceramics - Batteries - Electronics - Petroleum - Geology … and many, many more. A diverse array of sample materials can be tested with thermal analysis and calorimetry. This includes, but isn't limited to: - Thermoplastics - Epoxies - Copolymers - Reaction mixtures - Solutions - Solvents - Catalysts - Ceramics - Metals - Natural products like wood - Coal … and more. Other methods may be available. Contact us or call (506) 457-1515 to discuss how we can help with your testing needs.
