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.

Detecting the Adulteration of Extra Virgin Olive Oil by Controlled Cooling DSC

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

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.

HyperDSC for High Throughput Formulation Development

幸运8平台彩票The concept of High-Throughput Design has gained more and more interest as a way to increase profitability and to decrease research costs. One technique that can increase the ability of a laboratory to evaluate formulations is HyperDSC™ or High Ramping Rate DSC. HyperDSC is the ability to quantitatively measure small samples at extreme heating and cooling rates, typically 100-500 °C/min.

Isothermal Crystallization Study for Quality Assurance

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.

Measurement of the Tg' in Formulations

幸运8平台彩票In designed formulations for lyophilized drugs, it is important to know the collapse temperature of the cake. If the, collapse temperature is exceeded, the cake will collapse and the batch will be ruined. The collapse temperature is often associated with the Tg’ of the frozen material and measuring this transition is the best way to approximate it.
