Like DSC, DTA looks at the thermal transitions within a sample or analyte of choice. However, DTA looks at the thermal differences between a sample and a specific inert reference sample. DTA provides exact measures of enthalpy change within a sample with analytical precision and reproducibility. This is particularly useful for phase-change materials and the study of organic and polymeric materials.
Labsys Evo DTA 1200
Our Labsys Evo system allows for the analysis of a variety of organic and non-organic samples. TAL can offer services DTA analytical services from ambient temperature to 1600 °C, providing insight into the thermal transitions and phase changes within this temperature range. Additionally, this technique is perfect for evaluating the heat capacity or glass transition point of a polymeric material. Below is a list of the confines of our analysis:
