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!
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.
Identify is the most comprehensive database system in Thermal Analysis! In a nutshell, Identify can be used for the recognition and comparison of measurement curves. Signals of types DSC, TGA, DIL/TMA and cp are supported, curves can be found and overlaid easily. This article highlights the great database contents of Identify (status 11/2019): The Identify database already contains about 2300 database entries!
The heat flow meter (HFM) method is mainly used to test thermal conductivity and thermal resistance of insulation samples. It is not an absolute method, therefore, the heat flow meter output needs to be calibrated with a standard material. NETZSCH-Gerätebau GmbH has recently qualified its own factory standard for calibration and validation of heat flow … Read moreNETZSCH EPS – A New and Affordable Standard Material for Testing Thermal Conductivity with HFM Instruments
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)!
The database system for thermal analysis by NETZSCH, called Identify, has now (from Proteus® analysis version 8.0 or higher) already more than 2000 database entries available.
Furthermore, Identify can now be used with combined TGA+DSC, TGA-c-DTA® and STA measurements, which allows for material identification with greater certainty.
AutoEvaluation by NETZSCH is a very helpful tool for evaluation of thermoanalytical measurements. The entire measurement is evaluated by AutoEvaluation automatically and autonomously (not via pre-defined macro!) – with only one mouse click – and just within a second. AutoEvaluation is available for DSC, TGA and now also for STA measurements. Furthermore, the adaptability of AutoEvaluation is adressed.
