| Dec 06, 2012 | Thermal Analysis of Pharmaceuticals Thermal Analysis is often used to investigate pharmaceutical substances. Polymorphism, pseudo-polymorphism, phase diagrams, stability, and purity determination can all be measured by thermal analysis. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterizing such substances. The chief advantage is that properties can be measured as a function of the temperature or time over a wide temperature range, from –150 to 1600 °C. In this Webinar, we will show how thermal analysis is used to investigate pharmaceutical substances. We will present some typical examples measured by DSC, TGA, TMA or DMA. |
| Oct 24, 2012 | Differential scanning calorimetry (DSC) Differential scanning calorimetry (DSC) is the most frequently used thermal analysis technique alongside TGA, TMA and DMA. DSC is used to measure enthalpy changes due to changes in the physical and chemical properties of a material as a function of temperature or time. The method allows you to identify and characterize materials. Differential scanning calorimetry is fast, very sensitive and easy to use. In this Webinar, we will discuss the basic principles of DSC and present some interesting applications. |
| Sep 27, 2012 | Determination of the Glass Transition Glass transitions occur in all non-crystalline or semicrystalline materials and lead to significant changes in material properties such as thermal expansion, the specific heat capacity or modulus. Because the glass transition is very sensitive to chemical and physical structure, it can be used to characterize materials and is therefore important in most industries. Thermal Analysis provides different methods to measure the glass transition and the glass transition temperature. In this Webinar, we will discuss the basic theory of the glass transition and the different thermal analysis techniques and methods used to measure the glass transition and the associated glass transition temperature. |
| Aug 29, 2012 | Oxidation Induction Time (OIT) The determination of the oxidation induction time (OIT) and the oxidation onset temperature (OOT) are standard procedures frequently used to rapidly compare and assess the oxidative stability of materials. The same methods can be used to study aging processes and the effectiveness of stabilizers. The use of higher pressures suppresses the vaporization of volatile components, increases the rate of oxidation and shortens measurement times. In this Webinar, we will discuss the different methods used to investigate the oxidation behavior of materials and present some interesting applications. |
| Jul 26, 2012 | Thermal Analysis of Thermosets Thermosets are used for components that must be rigid, insoluble and of high mechanical strength and temperature stability. Production and processing are cheaper compared with metals. The four main techniques of thermal analysis, DSC, TGA, TMA, and DMA are ideal for characterizing such materials. The chief advantage is that properties can be measured as a function of temperature or time over a wide temperature range, from –150 to 1600 °C. In this Webinar, we will show how thermal analysis is used to analyze thermosets and will present some typical examples of samples measured by DSC, TGA, TMA, or DMA. |
| Jun 28, 2012 | Kinetics in Thermal Analysis Reaction kinetics is the study of the rates at which chemical reactions proceed. The method investigates the effect of temperature, catalysts, and other factors on chemical reactions and yields information about reaction mechanisms.
A good understanding of kinetics is very important, for example in the chemical industry for process development and safety investigations as well as in the polymer industry for understanding the curing behavior of thermosets. In this Webinar, we will discuss the basic principles of kinetics and present some interesting applications. |
| May 31, 2012 | Thermogravimetric Analysis (TGA) Thermogravimetric analysis (TGA) is widely used together with DSC, TMA, and DMA. TGA measures the mass of a sample while the sample is heated or cooled in a defined atmosphere. The main use of TGA is to characterize materials with regard to their composition. A TGA/DSC instrument even allows you measure thermal events that do not produce a mass change such as melting, glass transitions, or other solid-solid transitions. In this Webinar, we will discuss the basic principles of TGA/DSC and present some interesting applications. |
| On Demand Webinar | Dynamic Mechanical Analysis (DMA) Dynamic mechanical analysis (DMA) is used to measure the mechanical properties of viscoelastic materials as a function of temperature or frequency. It is one of the most important thermal analysis techniques alongside the well-established DSC, TGA, and TMA techniques.
DMA allows you to determine modulus values and measure relaxation effects that often cannot be detected by DSC. |
| On Demand Webinar | Validation in Thermal Analysis In analytical laboratories, most analyses are nowadays performed using computerized measurement systems. A validation process can be used to demonstrate fitness for purpose of the system before starting the experiments. The seminar presents the basic concepts step by step. The focus is on in-house method validation. The nine validation steps are described in detail using suitable examples. In this Webinar, we will discuss the basic principles of validation, from equipment qualification and computerized system validation through to analytical method validation. |
| On Demand Webinar | Thermomechanical Analysis (TMA) Thermomechanical analysis (TMA) is used to measure the dimensional changes of a material as a function of temperature. It is one of the most important thermal analysis techniques, complementary to the well-established DSC, TGA and DMA techniques. TMA allows you to determine expansion coefficients and softening temperatures. It can measure relaxation effects that are often not detected by DSC. In this Webinar, we will discuss the basic principles of TMA and present some interesting applications. |

| On Demand Webinar | Flash DSC 1 Flash DSC is a novel technique, a quantum leap in DSC technology that opens up new frontiers. The Flash DSC 1 revolutionizes rapid-scanning DSC thanks to its ultra-high heating and cooling rates. The state-of-the-art instrument can easily analyze reorganization and crystallization processes which were previously difficult or impossible to measure. The Flash DSC 1 is the ideal complement to conventional DSC for characterizing modern materials and optimizing production processes by thermal analysis. In this Webinar, we will discuss the basic principles of the Flash DSC 1 and present some interesting applications. |
| On Demand Webinar | Temperature Modulated DSC Techniques (TMDSC) Temperature-modulated DSC techniques (TMDSC) are widely used in thermal analysis in industrial and university research laboratories to separate overlapping temperature-dependent and time-dependent thermal effects. Methods used up until now have overlaid the isothermal temperature or heating ramp with a (usually) sinusoidal temperature modulation of just one frequency (single frequency method). In contrast, TOPEM® , the new advanced multi-frequency temperature-modulation technique, uses a large number of different frequencies (multi-frequency approach). The basic idea of TOPEM® is to overlay the isothermal or ramped temperature with a time series of stochastic (random) temperature pulses of different duration.

| On Demand Webinar | Calibration in Thermal Analysis You expect that your thermal analysis instrument is always accurate, true and precise and delivers reproducible results within a given range.
A calibration determines whether your module is delivering correctly measured values or needs an adjustment. In Thermal Analysis, different parameters must be calibrated (e.g. temperature, heat flow, mass, length, modulus). In this Webinar, we will discuss the basics of calibration and adjustment and give some useful tips and hints. |
