Simultaneous thermal analysis  (STA)(thermogravimetry and differential scanning calorimetry).

Simultaneous use of thermogravimetry (TG) and differential scanning calorimetry (DSC) is the simplest example of STA device, allows to obtain more information than using two separate devices.

 

The experimental conditions for the TG and DSC signals are identical (the same atmosphere, the flow rate, the vapor pressure of the sample heating rate, thermal contact with the crucible and the sensor, radiation, etc.)

 

The best analysis of the signals, as available at any time two or more sets of data describing the behavior of the sample, which allows to distinguish the phase shift of the decomposition reaction, the addition reaction of the condensation reaction of pyrolysis, oxidation and combustion, etc.

 

The very beginning of its existence, NETZSCH-Gerätebau GmbH gives high priority to the development and further optimization of their STA devices, currently occupying a leading position in the market research equipment due to their excellent performance.

 

NETZSCH STA instruments companies equipped with appropriate tools and the necessary standards for TGA and DSC.

  • ·        Unique for STA: temperature-modulated DSC (TM-DSC)

All these features make the new developed STA 449 F1 Jupiter® the ideal tool for thermal analysis of materials in the fields of research, developments and quality assurance.


NETZSCH STA 449 F3 Jupiter® - (STA: TG and DSC). 

The simultaneous thermal analyzer NETZSCH STA 449 F3 Jupiter® allows the measurement of mass changes and thermal effects between -150°C and 2400°C.

The high flexibility caused by the various sensors, the great variety of sample crucibles and the wide TGA-measuring range make the system applicable for analysis of all kinds of materials including also inhomogenous substances.

Easily interchangeable sample holders allow the optimal system adaption to the diverse application areas (TGA, TGA-DTA and TGA-DSC measurements).

Various furnaces, easy interchangeable by the user, cover the complete temperature range (please see accessories).

Through to the vacuum tight design measurements at defined atmospheres (e.g. inert) are possible.

The system is controlled by a newly developed integrated digital electronic device.
The analysis of measuring data runs under a standard PC and the well-proven Windows® software.


STA 2500 Regulus – Simultaneous Thermal Analysis.

Excellent Cost Performance

The STA 2500 Regulus features a highly reliable, fully equipped instrument package for STA measurements up to 1600°C at an attractive price.


Top-Loading and Unique Differential Balance Arrangement

The natural gas flow in the top-loading system guarantees automatic protection of the balance against condensation and contamination. The tailor-made differential balance system cancels out buoyancy and convection influences over a broad temperature range. This provides easy operation without the need for timeconsuming baseline runs.


Various Atmospheres Available

Measurements can be performed in inert and oxidizing atmospheres but also under vacuum. The atmosphere can be dynamic or static. The built-in mass flow controllers (MFCs) are software-controlled and allow gas changes at any time during the test.


Ideal for Evolved Gas Analysis

The top-loading design of the STA allows for convenient coupling to gas analysis systems such as FT-IR (Fourier Transform Infrared) spectrometer, MS (mass spectrometer), or GC-MS (gas chromatograph – mass spectrometer). During thermal treatment, the gases evolved can be simultaneously analyzed.
