GSA PT 100

High-pressure sorption analysis

Description

To the point

Linseis offers a wide range of measuring devices for gravimetric sorption analysis.
Our integrated solutions offer the possibility of independent control of pressure, temperature and gas dosing by means of supplied software.

The heart of the Linseis GSA PT 100 series is our unique magnetic suspension balance, which is characterized by a reaction chamber for very aggressive gases, as the weighing chamber is decoupled in this variant.
A large selection of reactors is available in a temperature range from -170 °C to 1800 °C and a pressure range from ultra-high vacuum to 300 bar.

The system can optionally be equipped with a gas and/or steam control.
A special water vapor generator for infinitely variable humidity control between 0-100 % is also available.
If desired, the system can also be equipped with gas analyzers for EGA (Evolved Gas Analysis) can be coupled.

With the Linseis GSA PT 100, sorption processes, diffusion processes, surface tensions and sample densities can be easily measured.
It is also suitable for investigating chemical reactions and production processes such as corrosion, decomposition and combustion, which can be perfectly simulated in the system.

Software

Making values visible and comparable

The powerful LINSEIS thermal analysis software, which is based on Microsoft® Windows®, performs the most important function in the preparation, execution and evaluation of thermoanalytical experiments, in addition to the hardware used.
With this software package, Linseis offers a comprehensive solution for programming all device-specific settings and control functions, as well as for data storage and evaluation.
The package was developed by our in-house software specialists and application experts and has been tried and tested over many years.

TG properties

  • Percentage (%) and absolute (mg/ug) change in mass
  • Evaluation of the mass loss
  • Residual mass determination
  • 1st and
    2nd derivative (peak temperature of the mass change)


HT-DSC properties
