GSA PT 100

High Pressure Sorption Measurements


On point

At the heart of the Linseis GSA PT 100 Series is our unique Magnetic Weighing Balance which features a very aggressive gas reaction chamber as the weighing chamber is decoupled in this variant. There is a large selection of reactors in a temperature range of -170 °C to 1800 °C and a pressure range of ultrahigh vacuum up to 300 bar available.

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

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

STA MSB Measuring system


All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a STA measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.
