TG 209 F3 Tarsus® Thermogravimetric Analysis - TGA Method, Technique and Applications Analyzing & Testing
Open the catalog to page 1What is the thermal stability of the material? Is the sample really the specified filled granulate? Is the sample contaminated with an additional component? Is the filler homogeneously distributed in the part? Of how many individual components does the rubber seal consist? How much solvent or plasticizer is released of the rubber mixture? How high is the added carbon black content? How high is the ash content of the polymer mixture? How does the thermal stability change under the influence of an oxidizing atmosphere? Is the melting of the thermoplastic already superposed by the start of...

Open the catalog to page 6Micro-Furnace for Dynamics in Day-to-Day Lab Tasks The low-volume furnace of the gas-tight NETZSCH TG 209 F3 Tarsus® consists of an SiO2-coated monolithic metallic heater with an integrated air cooler. Between room temperature and 1000°C, a heating rate of 200 K/min can be achieved for a high sample throughput. Safe handling is ensured by safety features. This includes purging of the balance chamber with protective gas. Precise Detection of the Sample Temperature The sample temperature is detected by a thermocouple in direct contact with the sample crucible. This ensures accurate reading of...
Open the catalog to page 7SmartMode -Run Professional Tests After Minutes of Introduction SmartMode boasts a clear structure, a consistent navigation design and easy-to-access buttons. Using wizards (measurement templates), it is possible to start a measurement with just a few inputs. Alternatively, customized methods or predefined methods can be selected to start an experiment. The predefined methods are based on different standards or measurements under reduced pressure. Even customers unfamiliar with the software immediately know how to proceed. ExpertMode -Perefct for Beginners and Professionals For those who...
Open the catalog to page 8AutoEvaluation* - Identify*- A Step AheadAutonomous Evaluation with the Database AutoEvaluation is a self-acting software package which evaluates the thermogravimetric effects, i.e., mass changes (decomposition reactions) without using stored evaluation macros. For all those who haven't seen such measurements yet, AutoEvaluation will handle the curve independently - without any effort on the operator's part. This ground-breaking technology allows, for the first time in history, test analyses which are fully user-independent and therefore completely objective. The Identify software searches...

Open the catalog to page 10Polymer Identification Made Easy – Even for Complex Elastomer Materials Characterization of Butadiene Rubber (BR) The plot shows a two-step decomposition of BR at 373°C (DTG peak) and at 470°C (DTG peak) in a nitrogen atmosphere (N2). The first step is due to unsaturated alkanes, the second to the cracking of the polymer back bone. In both decomposition steps, the sample nearly totally decomposes. The small amount of remaining mass in the N2 atmosphere most probably consists of pyrolytic carbon, which can be concluded from the fact that there is a mass loss of 0.2% after switching from...
Open the catalog to page 11-20 Determination of the Glass Fiber Content -2.0Polyamide 66 – % This PA66/GF sample was heated/°C Temperature to 800°C in an inert gas atmosphere at 20 K/min. Already between 70°C and 250°C, a considerable mass loss of 0.8% is determined (picture-in-picture TG /% presentation). Decomposition (68.8%) starts at approx. 360°C 158 °C with a maximum decomposition rate at 418°C (DTG peak). After -0.8 to switching% an oxidizing atmosphere at 800°C, the pyrolytic 418 °C carbon is burnt (1.0%). The remaining residue corresponds to the glass fiber amount (29.4%).
