Product details
Escaping gas analysis is an ideal tool for analyzing the thermal effects and corresponding chemical property changes of organic, inorganic solid or liquid samples.
The all-new Perseus STA 449F1/F3 combination system is NETZSCH STA 449 F1/F3 Jupiter®The perfect combination of synchronous thermal analyzer and Bruker ALPHA FT-IR infrared spectrometer. Its revolutionary design has become a new milestone in integrated technology.
This combined system has the characteristics of high performance, high compatibility, and compact design, suitable for various university research laboratories and industrial R&D departments engaged in inorganic or polymer spectral analysis.
Any existing NETZSCH STA F1/F3 system can be upgraded to the Persus STA FTIR combined system.
High cost-effective gas analysis technology
The Perses STA FTIR combined system has strong performance, moderate price, and can be widely used in various types of laboratories.
No need for liquid nitrogen
The FTIR part of the combined system uses a DTGS (deuterated glycine sulfate) detector, which no longer requires liquid nitrogen cooling. This system is particularly suitable for use in situations where automatic sampling or experimental time is long.
No need for separate gas transmission pipelines
The integrated system no longer requires gas transmission pipelines. The built-in gas heating unit is directly connected to the gas outlet of the furnace through a heating tube. This ultra short gas path design ensures fast response and can minimize the condensation of escaping gases.
Compact design
The design of the Persus STA FTIR combined system is compact, with the FTIR part installed directly above the STA instead of being placed side by side with the STA. Even for laboratories with limited space, there is no need to worry about instrument placement.
The Perseus STA system can be applied to the following research:
① Decomposition ② gas-solid reaction ③ component analysis ④ volatilization, gas release

Mixed building materials
Lime (CaCO3), hydrated lime (Ca (OH) 2), quartz (SiO2), and gypsum (calcium sulfate dihydrate) are widely used as classic building materials. In this experiment, a mixture of these substances was placed in a Pt/Rh crucible and heated to 1500 ℃ at a heating rate of 20K/min in an air atmosphere.
The following figure shows the TGA and DSC curves during the entire heating process. There are several weight loss steps in the TGA curve, corresponding to DSC peaks around 150 ℃, 453 ℃, and 779 ℃, respectively. The final weight loss peak appears between 1300 ℃ and 1400 ℃. On the DSC curve, several additional small peaks appeared: a small exothermic peak at 362 ℃ and a small endothermic peak at 576 ℃. A large endothermic peak appeared at 1216 ℃. From the thermogravimetric and DSC curves, it can be seen that there is no interaction between the components, and each material exhibits its own transformation and decomposition effects. Only when the temperature is above 1260 ℃, the observed decomposition may be superimposed with the melting of other materials. The combination of STA and FT-IR helps to explain such complex curves.
After combining FT-IR data, it can be seen that only water vapor escapes within 500 ℃. This is a typical dehydration process of gypsum dihydrate, which first changes from dihydrate to hemihydrate and then to anhydrous calcium sulfate. The second larger decomposition step (peak temperature of DTG at 453 ℃) is caused by the dehydration of Ca (OH) 2. The small exothermic peak on the DSC curve at 362 ℃ is due to the transformation of anhydrous calcium sulfate into β - calcium sulfate. The endothermic peak on the DSC curve at 576 ℃ is due to the phase transition of quartz from the alpha phase to the beta phase.
At around 780 ℃, CaCO3 decomposes to produce CO2. At 1216 ℃, a phase transition occurs from the β phase to the α phase of calcium sulfate, followed by the decomposition of calcium sulfate.

Lithium Cobalt Oxide Cathode Material - Thermal Stability (QMS)
Lithium cobalt oxide is widely used as a positive electrode material for lithium-ion batteries. The thermal stability of the positive electrode material is also an important factor in designing inherently safer and more efficient battery systems.
In this example, lithium cobalt oxide material that has undergone delithiation is taken out from a button battery and placed in a combination device of NETZSCH STA449F1 Jupiter and QMS 403 Aeolos Quadro for analysis. The positive electrode material exhibits several discrete decomposition steps during the heating process. With the help of mass spectrometry, it is easy to understand the decomposition pathway of materials and the deep structural changes of positive electrode materials after cycling.
