Linseis – High-pressure measuring devices

Linseis high-pressure measuring devices enable thermal analysis under extreme pressure conditions, crucial for studying material behavior in environments like oil, gas, or chemical industries. These instruments support various techniques, including Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA), ensuring precise results in challenging scenarios. Designed for durability and versatility, they cater to research and industrial applications needing robust high-pressure data.

Description

High-pressure thermal analysis

LINSEIS high-pressure thermal analyzers work according to the same measuring methods as their ambient pressure models, but can be operated at high temperatures up to 150 bar pressure.

This enables the investigation of pressure-dependent phenomena such as sorption or chemical reactions.

Both are of great interest for the development of new materials and processes for renewable (green) energies.

In hydrogen technology, hydrogen storage is crucial, and storage materials (metal hydrides) and storage conditions (pressure, temperature) need to be investigated.

Another example is biomass gasification.

The process parameters for the conversion of biomass into so-called syngas, which can be used as a fuel or as a precursor for methanol or other useful chemicals, can be investigated by varying the pressure, temperature and chemical composition of the gas atmosphere.

All this can be simulated in LINSEIS high-pressure analyzers.
