GSA PT 10 - Gravimetric Sorption Analyzer

Rapid and easy measurements

Gravimetric sorption analyzer

Gravimetric Sorption Analyzer Series - Linseis GSA PT 10:

Linseis offers a wide range of Gravimetric Sorption Analyzers. Our integrated solution offers the ability to independently software control the pressure, temperature and gas dosing. Our GSA PT 10 line is based on the standard linseis microbalance design. This ultra sensitive microbalance is available in two version 0,1 / 1ug for 5 / 25 g sample weight. A number of environmental chambers are available for operations from -150 up to 1750°C and UHV (ultra high vacuum) to 10 bar. An optional TG-DSC Thermogravimetry – Differential Scanning Calorimetry measuring head allows the simultaneous determination of weight change and caloric reactions in one run. Optional gas and vapor dosing systems as well as residual gas analysis is available.

Vapors and gases that can be used include: Alcohols, Hydrocarbons, Aromatics, Hydrogen, Water, Oxygen, Nitrogen, Argon, Carbon oxides, etc.

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.
