Key Features

• The ability to quickly and thoroughly analyze thermal stability, decomposition behavior, composition, phase transitions, and melting processes
• Exceptionally high balance resolution (25 ng resolution at a 5 g weighing range) in a top-loading system and maximum stability over the long run
• Variable system enhancements for optimal system adaptation to user-defined applications
• Interchangeable sensors for DSC measurements with maximum sensitivity and best reproducibility for reaction/transition temperatures and enthalpies as well as for measurements of specific heat
• Many furnaces that are readily swappable by the user are available (a swiveling double hoisting device for two furnaces is optional)
• Sample carriers that plugin (TG, TG-DSC, TG-DTA, etc.)
• Up to 20 sample automatic sample changers (ASCs)
• Autovac stands for automatic evacuation and refilling
• Many extras, such as sample crucibles, made of a wide range of materials and forms
• Temperature-modulated DSC (TM-DSC) is exclusive to STA
• Accessories for humid environments and the STA model for corrosive gases are available

Additional MS-and/or FTIR-coupling enables even more thorough analyses. The newly designed STA 449 F1 Jupiter^® is the perfect instrument for thermal analysis of materials in research, development, and quality assurance because of all these features.

Ceramics – Building Materials

It is well known that thermal analysis in conjunction with mass spectroscopy finds standard application in the cement, brick, and other building material industries. Although they can also include organic materials, the main constituents of cement raw materials are calcium carbonate, gypsum, and other intricate mixtures of ceramic materials.

Combining mass spectroscopy and thermal analysis provides a tool to simulate the production process of the subsequent building material in addition to aiding in the analysis and measurement of various raw material components.

Instrumentation and Test Conditions

QMS 403 AÑolos^® - STA 449 C Jupiter^® was used. Here is a list of the test conditions:

Results

Thermogravimetric (tG), differential scanning calorimetry (DSC), and mass spectroscopy were used to analyze raw cement material. Mass-loss steps and combined exothermal and endothermal effects were observed at 1500 °C.

The evolved gases and the cement raw material mixtures can be found with the mass spectrometer’s signals. At low temperatures, gypsum likely releases H₂O, and at about 480 °C, it releases Ca (OH)₂.

The temperature range for organic components' partial decomposition and burning was 300 °C to 400 °C—both the exothermal DSC peaks and the signals from the mass spectrometer support this conclusion. The evolution of CO₂ suggests that CaCO₃ decomposes at about 800 °C, whereas the evolution of SO2 suggests that CaS04 decomposes at the highest temperatures that can be measured.

The STA 449 F5 Jupiter for Thermogravimetry and DTA

The STA 449 F5 Jupiter from NETZSCH is a top-loading system for differential thermal analysis and thermogravimetry. The motorized furnace hoist and the top-loading principle of the balancing system allow for simple operation and sample changes.

The built-in balance’s high weighing and load range, low drift behavior, and high resolution combined with sensitive DSC capability to handle all common application tasks across a broad temperature range.

It is possible to perform true TGA and DSC measurements at sample temperatures ranging from room temperature to 1600 °C with excellent accuracy and repeatability. Flat baselines are provided by the integrated TGA-BeFlat software feature, which also removes the need for additional buoyancy correction work.

Furthermore, three integrated mass flow controllers for purge and protective gases offer the best possible control over the surrounding atmosphere of the sample.

Key Features

The STA 449 F5 Jupiter’s primary characteristics are:

• System for topping off with a balanced design
• Excellent performance and ease of use
• Sensitive DSC performance
• High range, low drift balance, and high resolution
• The STA system’s automatic backfilling and evacuation are made possible by the AutoVac feature
• Inbuilt mass flow regulators
• Even with large samples, TGA measurements are feasible
• Available with every feature of the hardware and software
