Differential Scanning Calorimetry (DSC) is a technique to provide insight into thermal transitions that do not cause a weight change. By monitoring heat flow over a time and at desired temperatures, we can provide insight into these material transitions. TAL offers the DSC analysis of a variety of organic, polymer, mineral and metallic samples from ambient up to 1600 °C (and ATD up to 1200 °C). We offer insight into a material’s phase changes (melting point, boiling point, fusion), heat capacity (Cp), and in the case of polymers, the glass transition temperatures (Tg). Additionally, we offer high pressure DSC analysis, using a pressured closed crucible (500 bar @ 600 °C), which is optimal for providing insight into low-vapour pressure liquids.

Labsys Evo DSC
Our Labsys Evo system allows for the analysis of a variety of organic and non-organic samples. TAL can offer services with closed and opened crucibles for monitoring reactions between samples and mixtures of gases. This is perfect for monitoring oxidation reactions, or more specifically reactions with ambient gases. We offer sample analysis from ambient temperatures up to 1600 °C, and under a variety of gas mixtures or under vacuum. This is perfect for evaluating the heat capacity or glass transition point of a polymeric material, or additionally give insight into the phase-change of our material of analysis.

µDSC 7
The analysis of the thermal properties of a material under pressure is important. Oils, rubbers, polymers and other functional materials need to perform under stress, or under a great deal of pressure. We can offer DSC analysis experiments performed from ambient to 400 bar using a variety of pressuring gasses. TAL also uses a 3D Calvet type sensor, which offers greater sensitivity for measuring small thermal transitions, or difficult to detect heat flow changes. Compared to traditional 2D sensor analysis, we offer analysis on smaller sample sizes, with highly reproducible results using this specialized sensor.

DSC 131
TAL offers DSC analysis services using fluid-tight crucible materials. This is important for exploration the thermal properties of liquids or melt materials which possess a high vapour pressure. Vaporization, decomposition or polymerization reactions can be studied using this cell. This can provide information such as the heat capacity of a liquid under its own vapour pressure, with applications towards the energy sector or materials. TAL also offers regular DSC analysis on larger sample sizes up to 700 °C.
