NETZSCH recently announced the release of the STA 449 F5 Jupiter®. Designed in the company’s top-loading instrument configuration, the NETZSCH STA 449 F5 Jupiter reportedly provides ultimate ease of use. The instrument is optimized to offer a variety of measurement tasks at an attractive price-performance ratio.
This instrument simultaneously performs thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) on a single sample, reportedly yielding more information than separate tests using two different instruments. The test conditions are identical for the TGA and DSC signals, including gas atmosphere and flow rate, vapor pressure on the sample, experimental heating rate, thermal contact to the sample crucible and sensor, and so on. Combining these two sets of data signals allows for differentiation between phase transformations and decomposition behaviors, distinguishing addition from condensation reactions, recognition of pyrolysis, oxidation, and combustion reactions, among other sample behaviors. The vacuum-tight STA 449 F5 Jupiter® is reportedly designed for simplicity and has been customized specifically for the end-user’s application. Each instrument comes pre-configured with all of the hardware and software features required by high-temperature applications in the fields of ceramics, metals, inorganics, building materials, etc.
The instrument comes with a silicon carbide (SiC) furnace capable of routine operation to 1,600°C. At the heart of the instrument is a top-loading, highly sensitive low-drift micro-balance. In combination with a rotating motorized furnace hoist, this design allows for the sample—and, if necessary, the sensor—to be changed easily and safely. In order to implement measurement routines quickly, a software solution for automatic baseline correction called TGA BeFlat® is included. The system’s thermobalance covers a full 35 g measuring range, while its sensitive DSC capability enables accurate measurement of heat flow and characterization of energetic behaviors. TGA measurements are also possible on large or heavy samples.
The STA 449 F5 Jupiter comes standard with both AutoVac for automatic evacuation and refilling of the measurement system and mass flow controllers (MFCs) for precise control of purge and protective gases. This allows for the simultaneous determination of caloric effects and mass changes under both oxidizing and inert atmospheres. Two instrument versions (with or without automatic sample changer) are available, each including a TGA-DSC sensor. In lieu of the TGA-DSC sensor, a large-sample TGA-only sample carrier or a TGA-DTA sensor can optionally be employed.
