PERSEUS® STA 449 F1/F3 Jupiter®

The Revolution in STA-FT-IR Coupling

Evolved Gas Analysis (EGA) is the perfect tool for characterizing the thermal behavior of organics, inorganics or polymers in more detail, elucidating the chemistry behind the processes.
The  PERSEUS® STA 449 F1/F3 Jupiter® is an unmatched alliance between two successful instruments: the NETZSCH STA 449 F1/F3 Jupiter® and the FT-IR spectrometer by Bruker Optics. Its design is unprecedented and sets a benchmark for state-of-the-art coupling systems.

Due to its robustness, high performance, compactness and attractive price, this combination instrument has the potential to find its way into any laboratory – be it in universities or industry, across the spectrum from inorganics to polymers.

Any existing NETZSCH STA 449 F1/F3 Jupiter® system can be upgraded to the PERSEUS®.

Affordable Gas Analysis

The unrivaled instrument alliance serves as an innovative coupling technique, even for a narrow budget. It has what it takes to become an integral part of any laboratory and indispensible for its future needs.

No Liquid Nitrogen required

The DLaTGS (DLaTGS = deuterated L-alanine doped triglycine sulphate) detector used does not require any liquid nitrogen cooling. This system is therefore particularly well-suited for test runs with an autosampler (ASC) or for measurements of longer duration.

No Separate Transfer Line

The built-in heated gas cell is directly connected to the gas outlet of the furnace via a heated tube. The low volume of this short gas path guarantees fast response and is quite advantageous in cases where condensable evolved gases are present.

Space-Saving Design

No separate FT-IR spectrometer is necessary, the footprint of the PERSEUS® STA 449 F1/F3 Jupiter® coupling is identical to that of an STA 449 F1/F3 Jupiter® alone. This makes the coupled system ideally suited for labs in which space is scarce.

The Proteus® Software for thermal analysis and the OPUS software for FT-IR, both of which run on Windows®, are integrated with each other and work well together in support of the PERSEUS® STA 449 F1/F3 Jupiter® coupling. All information is expressed as a function of temperature and time of the running experiment.

The Proteus® Software includes everything you need to carry out a measurement and evaluate the resulting data. User-friendly menus and automated routines make this software very easy to use while still providing sophisticated analysis. The Proteus® Software is licensed with the instrument and can of course be installed on other computer systems.


  • Simultaneous measuring, data acquisition, and data storage with two software packages: Proteus® (by NETZSCH) for thermal analysis data, and OPUS (by Bruker Optics) for FT-IR spectra and traces
  • OPUS/CHROM software as 2D and 3D plots for FT-IR and STA measuring curves, as a function of time and temperature
  • OPUS/SEARCH with spectra library
  • Traces for evaluation of characteristic temperatures and peak surface together with thermal analysis curves
  • Gram-Schmidt plot with temperature and peak area calculation together with thermal analysis curves

You can use the following software with this product:

Proteus® Software




With the PulseTA® technique an exactly defined quantity of gas is injected to the purge gas of the thermobalance (TGA) or the simultaneous thermal analysis instrument (STA).

Automatic Sample Changer

The automatic sample changer (ASC) for up to 20 samples similarly handles routine measurements in quality control as well as requirements for research and development. It works around the clock to free your time for other challenges and allows you to make optimal use of the PERSEUS® STA 449 F1/F3 even during the weekend. Of course, each sample can be assigned a different measurement and evaluation program. Easy-to-understand input fields lead you through the programming of a series of measurements. Unplanned analyses can also be inserted into a pre-programmed series of measurements already in progress.

Application literature

Application literature

Evolved gas analysis (EGA) from thermal analyzers such as thermogravimetry (TG) or simultaneous thermal analysis (STA) which refers to simultaneous TG–DSC is well established since it greatly enhances the value of TG or TG–DSC results.



The new PERSEUS® STA 449 F1/F3 Coupling has a compact 2-in-1 design, a clever combination of STA and FT-IR. It occupies 60% less bench-top space and requires no separate transfer line.

Flexibility with the fittings of this premium instrument for thermogravimetry allow it to cover almost any imaginable application in the range up to 1100°C. The system has many outstanding features: BeFlat® function allows or immediate measurement upon switching on the unit, the system’s heating rates of up to 200 K/min allow for faster results, while its corrosion-resistant ceramic furnace withstands even fluorine- or chlorine-containing polymers, c-DTA® function for the detection of exothermal and endothermal reactions.

TGA/STA-GC-MS Coupling

NETZSCH, in collaboration with JAS (Joint Analytical Systems), has forged a breakthrough improvement in evolved gas analysis (EGA). What sets the new coupling system apart is the fact that the start of the measurement is event-driven. This enables temperature-correlated detection of the substances released, which in turn allows for direct correlation with mass loss steps.
