Purity Determination by Thermal Analysis Webinar

Differential scanning calorimetry (DSC), widely used to study materials behavior and properties as a function of temperature or time, is often used to determine materials purity. What purity means, why it is of interest, and other questions will be answered in a free purity determination webinar from Mettler Toledo.

Mettler Toledo presents “Purity Determination by Thermal Analysis” on July 28, 2016. The English-language webinar is part of the lab technology company’s year-long thermal analysis series. Covering a variety of DSC purity determination applications, the presentation will repeat live three times to allow participation from around the world.

DSC is a widely used thermal analysis technique. It is also often used to study the purity of a main sample component in research, development, and quality control across industries such as pharmaceuticals, chemical, petrochemical, and foods. Additionally, only a few milligrams of a sample being studied are required for analysis. Because of this, DSC has proven to be cost-effective when working with rare or expensive substances.

One of the most well-established applications for the DSC method is organic substance purity determination. The method is based on the Van’t Hoff Law of melting point depression of eutectic systems. Purities between 90 and 100 mol% can be reliably determined, as can the melting point of a pure substance.

The webinar will explore this and other DSC principles, as well as how they are applied to the study of purity via a range of specific pharmaceutical, food ingredient, and chemical industry application examples.
