Hyphenated Techniques - Evolved Gas Analysis

PERSEUS STA 449 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 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 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 Jupiter coupling is identical to that of an STA 449 Jupiter alone. This makes the coupled system ideally suited for labs in which space is scarce.

The PERSEUS STA 449 Jupiter can be employed for the following application areas:

  • Decomposition
  • Solid-gas reactions
  • Compositional analysis
  • Evaporation, outgassing
