The processing and handling behavior of food fats has been found to depend upon the solid-to-liquid fat ratio in the food sample. Many rheological or flow properties, and their resultant effect on the texture of the final product, stem from this fat ratio index. The Power Compensation or double furnace DSC yields excellent results for foods including the fat nature and content. The fast responsiveness of the Power Compensation DSC provides the highest possible resolution and this is critical for characterizing the various polymorphic melting forms associated with fats in foods.
Differential scanning calorimetry (DSC) is a commonly used technique for studying polymeric; pharmaceutical; and energetic; materials. When considering which type of DSC to use to perform a specified measurement one typically chooses either a Power Compensation, or heat flux design.
Organic solar cells (OSCs) are a new type of photovoltaic technology for converting solar energy into electrical energy. They have excellent characteristics such as wide material sources, light weight, simple preparation process, and flexibility. Polymer/fullerene solar cells using conjugated polymers as electron donors and fullerene and its derivatives as electron acceptors are currently important research topics. Through molecular design strategies, the basic properties of polymers and fullerenes and their derivatives are optimized. These properties include the absorption spectrum, molecular energy level and mobility of the two, and the degree of crystallinity. Among them, the crystallinity of the active layer material is also closely related to the energy conversion efficiency of the battery. Differential scanning calorimetry (DSC) can directly measure the melting enthalpy of the active layer material and infer the level of crystallinity of the material. This allows the user to estimate energy conversion efficiency and therefore infer the best ratio of electron donor and electron donor in the active material.
This application note discusses how PerkinElmer DSC 4000 differential scanning calorimeter is used to test the heat flow curve of active layer materials in an organic solar cell, and the calculation of enthalpy of melting based on the melting peak to determine the molecular alignment and compatibility of the material.

Many pharmaceutical materials exhibit polymorphism, and depending upon the given processing conditions, the crystalline form may exist in two or more states. The existence of these polymorphic crystalline states is important for many pharmaceutical materials, as they can have a major effect upon the uptake of the active drug into the bloodstream once ingested and the shelf life of the drug. Differential scanning calorimetry (DSC), particularly power compensated DSC, has proven to be an extremely valuable technique for the characterization of polymorphism in pharmaceutical materials. This application note describes how the PerkinElmer DSC 8500 provides high sensitivity and unsurpassed resolution necessary to detect polymorphism exhibited by many pharmaceutical materials.
OIT is the abbreviation for oxidative induction time. It provides information about the oxidative stability of mainly polymer materials. The information is important because plastic parts age throughout their lifetime due to exposure to environmental elements such as heat, oxygen, light and radiation. Aging causes the degradation of the physical properties of the polymers and will lead to their failure.
Increasing the sensitivity and throughput of Differential Scanning Calorimetry (DSC) analysis has always been a challenge for thermal analysts in research and development. DSC analysis becomes difficult for small sample sizes, high throughput applications, materials that may experience re-crystallization during melting or that decompose immediately after melting; resulting in unexpected thermal phenomena.
HyperDSC is a DSC analysis technique by PerkinElmer with fast scanning rates that eliminates or significantly reduces such unknown thermal behavior, enabling increased sensitivity and high throughput. Accurate interpretation of results and fast scanning make HyperDSC the preferred tool of the pharmaceutical and polymer industries to reduce time-to-market for new products and increase manufacturing efficiency. Read the application note to learn more about the benefits of HyperDSC for several applications in polymers and pharmaceuticals.
One of the more commonly used thermoplastics is polypropylene because of its versatility. As with all thermoplastics, it is important to characterize the thermophysical properties of polypropylene, including melting temperature, percent crystallinity, crystallization when cooling from the melt, and the glass transition temperature, Tg. It is essential to analyze the thermophysical properties of the end product for quality assurance purposes. Thermal analysis provides an ideal means of characterizing the properties of polymers, including polypropylene. Differential Scanning Calorimetry (DSC) is a particularly useful technique for the characterization of polypropylene. This application note demonstrates how the high performance DSC from PerkinElmer® can readily detect the Tg of polypropylene.

StepScan DSC is a temperature modulated,DSC technique that operates in conjunction,with the Power Compensation Diamond,DSC from PerkinElmer. The approach,applies a series of short interval heating,and isothermal hold steps to cover the temperature range of interest. With the,StepScan™ DSC approach, two signals are obtained: the Thermodynamic Cp,signal represents the thermodynamic aspects of the material, while the Iso K,signal reflects the kinetic nature of the sample during heating. The following,basic equation mathematically describes the StepScan DSC approach:
