NETZSCH EPS Standard Material for HFM Instruments: A Question of Reproducibility

When discussing the reproducibility of measurement results in general, what is known as the “reproducibility conditions” must always be taken into account. Measuring exactly the same specimen several times with exactly the same measuring device is usually not considered to be a reproducibility test, but a repeatability test. In order to draw conclusions about the … Read moreNETZSCH EPS Standard Material for HFM Instruments: A Question of Reproducibility

Optimizing Reactive Injection Molding with In-line Sensors

NETZSCH and KISTLER, two family owned companies, offer the most advanced process package for reactive injection molding targeting zero waste production while at the same time a maximum in efficiency with an increased throughput is enabled.

Sub-ambient DMA Measurements up to -70°C without Using LN2

Many investigations in the field of polymers with lower stiffness require a measurement start below room temperature. As an alternative to existing solutions with Vortex tube and liquid nitrogen cooling, NETZSCH now offers the new compact AIC 80 intracooler for DMA measurements that works with chilled air. It reliably cools samples to -70°C without the use of liquid nitrogen.

How to use TGA for the quality control of carbon fiber-reinforced polymers

CFRP_TGA_quality control_netzsch

The determination of fiber volume fraction is crucial for the quality control of carbon fiber-reinforced polymers (CFRP) in order to ensure their favorable mechanical and physical properties for the use in aerospace, wind energy and automotive sectors. A new thermogravimetric testing method, published by Dominik Grund in the journal “Polymer Testing”, considers heating rate, analysis atmosphere and sample size to efficiently ensure high quality of the material. This editorial summarizes the steps for the use of TGA in the quality control of carbon fiber-reinforced polymers.

Good Stability Versus Good Tabletability: The Choice of Modification

Many pharmaceutical solids exhibit polymorphism, i.e., the ability of a substance to exist in different crystalline forms. The polymorphic form can have significant influence on pharmaceutical processing and can, for example, affect grinding, granulation and tabletability. A DSC measurement allows for the characterization of the present modification. Here, different modifications of paracetamol are distinguished by means of DSC.

Lambda-Measurement and the Fight against Condensing Humidity

Insulating Materials

Humidity plays a major role in the quality assurance of insulating materials. Ignorance in dealing with condensation and establishing good measurement conditions can result in unexpected measurement results. This article shows methods, that helps to overcome condensation issues in the quality assurance of thermal insulation materials.

How mechanical properties of polymers change with temperature

Professor Dr Tim. A. Osswald and Dr Tobias Pflock talk about the effect temperature has on the polymer’s properties. The room temperature modulus is often the only value given to describe the mechanical property of a polymer material. But temperature dependence of mechanical performance of polymer material significantly differs to that of other materials such as metals or ceramics and is vital information for many everyday applications of polymers.

How DSC Measurements help with Phase Diagrams – A Possibility for Determining the Composition of a NiAl Alloy

FreeImages.com/mireque kodesh

E. Post, J. Blumm

A phase diagram portrays the equilibrium conditions between the thermodynamically separated phases or it shows which phases are present in the material system at different temperatures, pressures and compositions. Thermoanalytical methods play an important role in establishing binary and ternary phase diagrams. They are based on the principle that, when a phase transition occurs, the physical, chemical and/or structural properties change.

Smart Thermal Analysis (Part III): Automatic Evaluation of DIL and TMA Curves

AutoEvaluation by NETZSCH is an intelligent software functionality which can automatically and autonomously (not via pre-defined macro!) evaluate thermoanalytical measurement curves. This is not only helpful but also time-saving! AutoEvaluation was introduced for DSC, TGA and STA and is now available also for dL signals from Dilatometer (DIL) and Thermomechanical analyzers (TMA)!
