Simultaneous Thermal Analyzer – STA 449 F5 Jupiter® Analyzing & Testing

Simultaneous Thermal Analysis – Two Methods Going Well Together Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of Thermogravimetry (TG, TGA) and Differential Thermal Analysis (DTA) or Differential Scanning Calorimetry (DSC) to the same sample in one instrument. In the STA, the test conditions are perfectly identical for the TGA and DTA/DSC signals (same atmosphere, gas flow rate, heating rate, thermal contact to the sample crucible and sensor, etc.). Sample throughput is also improved as more information is gathered from each test run....

The NETZSCH STA Eco-Line 70% LESS ENERGY AND COST. NO EXTERNAL TEMPERATURE CONTROL NEEDED. To obtain exact Thermogravimetric results with low drift behavior, most manufacturers have to resort to thermostatic control using a water cycle. Having to run the thermostat continuously requires a lot of energy and produces waste heat, which subsequently needs to be regulated by air conditioning. NETZSCH has succeeded in removing the external thermostat. The weighing chamber’s temperature is now regulated electronically, while maintaining excellent temperature stability. By removing the thermostat,...

Top-loading – The Proven Design for Thermobalances The STA 449 F5 Jupiter® is a toploading system using a balance design that has been standard for years in laboratories. The reasons are simple: These systems combine ideal performance with easy handling. by arks nchm vation ng Be no Setti nce & In rie Expe Easy Operation The STA 449 F5 Jupiter® is designed to guarantee easiest operation. Sample change can be performed safely via the motorized furnace hoist and top-loading principle of the balance system. The integrated software feature TGA-BeFlat provides flat baselines and eliminates...

Unique Combination – True TGA-DSC and High-Volume TGA Atmosphere – Perfectly Controlled by MFC and AutoVac* Between ambient and 1600°C sample temperature, combined TGA and true DSC measurements can be performed with high precision and reproducibility. TGA measurements are also possible even on large samples – crucibles up to 5 cm3 in volume are available. The three built-in mass flow controllers (MFC) for purge and protective gases provide an optimum control of the atmosphere around the sample. The AutoVac* feature allows for automatic evacuation and backfilling of the STA system. This...

Accessories and Options Tailored to Two True Measurement Techniques, Easy-to-Add Accessories and Ready for Gas Analysis Two Methods – More Effective Together The system is equipped with the TGA-DSC sensor. True DSC or simultaneous TGA-DSC measurements can also be performed simultaneously using the automatic sample changer (ASC). Crucibles made from different materials and in various dimensions are available. Standard crucibles are made of alumina or platinum. Many crucibles, e.g., gold, zirconia, etc., can be offered with solid or pierced lids. You can choose the right type for your...

Your Application Automatic Sample Changer Provides Peace of Mind All Set! – Ready for Coupling to Evolved Gas Analysis An automatic sample changer (ASC) for up to 20 samples is optionally available. It can be used for TGA or TGA-DSC measurements. The ASC guarantees optimal crucible placement and maximum throughput. Preprogramming allows measurements to be carried out during the night or weekend. By use of predefined methods, handling is even further facilitated. For evolved gas analysis (EGA), the STA system can be coupled to QMS and FT-IR individually or to a combination of QMS and FT-IR –...

Proteus® software is produced by an ISO-certified company and includes everything you need to evaluate the resulting data, and even perform complicated analyses. STA 449 F5 Jupiter® with Proteus® 8.0 OUR POWERFUL ANALYTICAL SOFTWARE BeFlat – An Intelligent Way to Save Time The TGA-BeFlat software feature keeps a record of the temperature as a function of the measuring influences – including the heating rate, the different purge gases and the gas flow rates – and can therefore provide the appropriate correction for the selected measurement conditions without having to carry out a blank value...

STA measurement of calcium oxalate monohydrate (sample mass 12.79 mg) in Pt crucibles and at a heating rate of 10 K/min in nitrogen atmosphere (70 ml/min). Accuracy of the TGA Signal In thermal analysis, calcium oxalate monohydrate (CaC2O4·H2O) is used to determine the accuracy of the TGA signal. The substance has a high stability and adsorbs little moisture from the laboratory environment. This makes it an ideal reference material for thermobalances. This plot shows the TGA and DSC curves of CaC2O4·H2O between room temperature and 1000°C. The 1st mass-loss step shows the release of water...

APPLICATIONS Melting Point of Palladium The largest use of palladium (Pd) today is in catalytic converters. However, it is also used in, e.g., dentistry, aircraft spark plugs and surgical instruments and electrical contacts. Palladium shows no reaction with oxygen at normal temperature although when heated to 800°C in air will produce a layer of palladium(II) oxide (PdO). This plot exhibits the STA measurement on Pd up to a sample temperature of 1600°C. The DSC curve (blue) shows the melting with an enthalpy of 158 J/g (blue curve, DSC) at 1554°C (onset temperature). Both values correspond...
