Confirming Polymorphic Purity with HyperDSC

Many materials have complex molecular structures that areable to exist in more than one crystalline form, a phenomenontermed polymorphism. Different forms may have differentproperties and, for pharmaceutical use, it is important tobe able to produce a pure and stable crystalline form of any material to be used as a drug compound. Using a Differential Scanning Calorimeter (DSC), different forms of such materials may be identified from their melting profiles and differing melting points.

Determination of Critical Cooling Rate for Hardening Aluminum Alloys using HyperDSC

When an aluminum alloy is solution annealed andafterwards cooled too slowly, an exothermal precipitationreaction occurs. With increasing cooling rate, theprecipitation heat decreases. Since the precipitation reaction is relatively fast, a fast cooling rate on the differential scanning calorimeter (DSC) is essential to obtain the critical cooling rate which is the minimum cooling rate at which no precipitation heat is detectable. In this case, it was determined to be 375 (±10) K/min. Such a fast cooling rate can be realized through PerkinElmer’s HyperDSC® technology.

High Resolution Characterization of Pharmaceutical Polymorphs Using Power Compensation DSC

幸运8平台彩票Many pharmaceutical materials exhibit polymorphism, which means that, depending upon the given processing conditions, the crystalline form may exist in two or more states. The crystalline states or forms exhibit different levels of thermodynamic stabilities and an unstable form can melt at a temperature significantly less than the melting point of the thermodynamically stable form. Depending upon the conditions used to generate the crystalline form(s), the drug may exhibit one or more unstable, polymorphic crystalline states.

Importance of DSC Rapid Cooling for the Analysis of Plastic Microwave Food Trays

幸运8平台彩票Most DSC experiments on polymers are conducted by heating from ambient conditions to above the melting temperature. But, for some thermoplastics, which do exhibit differences during processing, standard heating DSC may not show any significant differences. A more sensitive test, for detecting subtle, but important differences between different batches of a given thermoplastic, is the DSC isothermal crystallization test.

Improved HyperDSC Method to Determine Specific Heat Capacity of Nanocomposites and Probe for High-Temperature Devitrification

Where ΔCp and ΔCp pure are the changes in specific heat at the glass transition temperature, Tg, for the composite, and for the unfilled polymer, respectively. This work suggests an alternative method for determining Cp that takes advantage of fast heating and cooling rates to obtain quantitative Cp in the upper temperature region without having to dwell in that high temperature region to establish an upper isothermal.

Isothermal Crystallization Study for Quality Assurance

幸运8平台彩票Therefore, it is a sensitive test and can be used to show the difference between various batches of material, which may show little difference under a conventional heating experiment. Batches with different crystallization behavior will lead to variation in the quality of the final processed product. For polymer resin manufacture, it can be used for, quality assurance purposes, the optimization of resin formula or the evaluation of a competitor’s resin.
