If the extraordinary events of 2020 have taught us anything, it is that collaboration and teamwork are the best foundation for success. That is why we, NETZSCH Analyzing & Testing, and the NETZSCH Group, are pleased to be stepping up our cooperation with Malvern Panalytical.

Imagine the typical situation in everyday laboratory work: A new sample has to be analyzed, but what are the suitable measurement conditions such as temperature program, sample mass or the right crucible? And what measurement results can be expected? Perhaps such kind of sample was already measured by you in the past ‒ or maybe by NETZSCH. Wouldn’t it help a lot to simply search in a database for thermal analysis? Identify, which is a part of the Proteus® analysis software, is the solution!
Eine der Komponenten in einer Lithium-Ionen-Batterie, die typischerweise für Probleme verantwortlich ist, ist der Elektrolyt. Im folgenden Artikel werden mehrere Experimente mittels TGA, DSC und Gasanalyse durchgeführt, um die Zusammensetzung und thermische Stabilität zu untersuchen und die freigesetzten Produkte zu identifizieren.
Thermogravimetry (TGA) is frequently applied for the compositional analyses of such materials as, for example, fiber-reinforced polymer composites. The residual mass at the end of a TGA experiment reflects the filler or glass fiber content as well as the presence of impurities. By using a relatively large sample volume in a top-performing thermobalance along with the intelligent Proteus® software by NETZSCH, it is possible to detect ultra-small residual masses with concentrations down to the ppm (= 10-6) range! Such small concentrations can be illustrated by a little bird with a mass of a few grams sitting on the back of an elephant weighing a few tons.
Polymermischungen bieten während ihrer Lebensdauer erhebliche Vorteile. Sie erschweren jedoch das Recycling am Ende ihres Lebenszyklus. Eines der grundlegendsten Probleme ist die Identifizierung des Materials als Blend sowie seine Zusammensetzung, um sicherzustellen, dass es richtig sortiert wird und wenn möglich wiederverwendet werden kann. Lesen Sie, wie TGA und FT-IR bei der Identifizierung helfen können!
One of the components found in a lithium ion battery that is typically responsible for mishaps is the electrolyte. In the following article, several experiments were conducted via TGA, DSC and evolved gas analysis to investigate composition, thermal stability and identify the released products.
Polymer blends offer significant advantages during their service life. However, they make recycling at the end of life difficult. One of the most fundamental problems is the identification of the material as a blend as well as its composition to ensure it is sorted properly and can be reused if possible. Read how to TGA and FT-IR help with the identification and join our webinar series on TG-FT-IR!
The University of Queensland, in collaboration with the Non-Conforming Building Products (NCBP) Audit Taskforce in Queensland, Australia, have proposed a framework to provide a robust methodology to assess the fire hazard of cladding materials in existing buildings based on a thorough understanding of the relevant fire phenomena. Thermogravimetric Analysis enhances the robustness of the framework. Read here how the method is applied to evaluate the risk of external fire spread on buildings.
In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.
Water is one of the major parts influencing our climate. Our atmosphere is filled with water. We may not always be able to see it, but it interacts with us and our materials. Learn how thermal analysis helps identify water absorption and determine water content.
