This application note demonstrates the use of the Double Furnace DSC for the better and more complete characterization of hot melt adhesives.
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 fromthis fat ratio index. The Power Compensation or double furnace DSC yields excellent results for foods including thefat 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.
The aliphatic polyketone copolymer (PK copolymer) is a perfectly alternating copolymer of ethylene and carbon monoxide. It exhibits many desirable engineering thermoplastic properties, such as a high tensile yield stress and an excellent impact performance. Its high degree of chemical resistance and superior barrier properties make this polymer an interesting, new thermoplastic for engineering applications. HyperDSC® is the premier fast scan Differential Scanning Calorimetry (DSC) technique from PerkinElmer. This application note demonstrates that HyperDSC technique is really the most effective and most sensitive DSC technique available at the moment for the characterization of both the crystalline and the amorphous phase of a polymeric system.
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.
Many polymers are semi-crystalline material. The percentage of crystallinity depends on many factors including chemical structure, interaction between polymer chains and processing conditions. One typical example is High Density Polyethylene (HDPE), a highly crystalline engineering thermoplastic. Historically, the glass transition for a highly crystalline material like HDPE could not be determined by Differential Scanning Calorimetry (DSC) since the step change in the heat flow signal as the material is heated through its glass transition cannot be observed at traditional scanning rates. In this study, an HDPE sample is used to demonstrate the increased sensitivity and ability to detect weak glass transitions with HyperDSC® using the PerkinElmer® DSC 8500.
Differential scanning calorimetry (DSC) is commonly used to analyze foods in both quality control and research labs. DSC is often used to compare materials on heating, but cooling studies often give more information as materials can respond more thermodynamically under controlled cooling.
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.
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.
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.
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.
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.
Isothermal crystallization 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. 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. This application note demonstrates why PerkinElmer® DSC 8000 with power compensation is the ideal tool for isothermal crystallization experiment.
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.

DSC and Raman spectroscopy are both used to investigate crystallinity but in rather different ways. DSC can determine the degree of crystallinity very precisely and can also follow the kinetics of crystallization by measuring the associated enthalpy changes.
DSC and Raman spectroscopy are complementary techniques that are often applied to the same problems, principally to study phase transitions in solids. PerkinElmer’s state-of-the-art double-furnace DSC is heavily used in material characterization.
DSC is a thermal analysis technique to measure the temperature and heat flows associated with phase transitions in materials, as a function of time and temperature. DSC is particularly suitable for analysis of food systems because they are often subject to heating or cooling during processing. The calorimetric information from DSC can be directly used to understand the thermal transitions that the food system may undergo during processing or storage. DSC is easy to operate and in most cases no special sample preparation is required. With a wide range of DSC sample pans available, both liquid and solid food samples can be studied. In this note, several samples of food material systems are given to illustrate the versatility of DSC.
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:
Heat capacity measurement has been performed in order to detect a possible second Tg on nanocomposites of polymethyl methacrylate (PMMA) with silicon oxide nanoparticles of different shape. StepScan™ DSC was used for determination of precise heat capacity and HyperDSC® to prevent degradation and identify devitrification of the RAF at elevated temperatures.
The assembly and packaging phase of semiconductor manufacturing requires failure analysis and quality control processes which are of critical importance to final product quality and performance. Analytical measurements like Thermal Analysis allows users to analyze the thermal behavior of epoxies used in packaging, provides insights into material selection like slight weight changes used to measure important mate¬rial parameters like outgassing properties and thermal stabil¬ity, measure dimensional changes in material when subject to a temperature program, and many more.
Learn how Thermal Analyses applications can lead to great cost savings for semiconductor R&D and QA/QC.
The UV curing of resins is important in materials science. Direct energy measurement and true isothermal operation are essential to a successful UV curing experiment. Since the UV curing reaction is fast, a fast response DSC is needed to capture the process. The double-furnace power-controlled DSC 8000/8500 with UV accessory is the ideal tool to study the UV curing process and to characterize the material properties before and after the UV curing.

A simple experiment is suggested to demonstrate the response time of a DSC and to show how much time is needed for equilibration.
A calorimeter is a device that measures the heat exchange of a sample with its environment. Since heat is usually generated or consumed during a physical transition or chemical reaction; calorimetry is a universal tool to study such processes.
High throughput is a common concern for manufacturing environments. Recently, it has grown in importance for today’s busy research and analytical laboratories as well. Automation can be key to increasing a laboratory’s capabilities while freeing an analyst’s time for other work.
