Gravimetric Sorption Analyzer

Gravimetric Sorption Analyzer from UHV up to 1000 bar

Linseis offers a wide range of Gravimetric Sorption Analyzers (GSA). Our integrated solution offers the ability to independently software control the pressure, temperature and gas dosing. We offer two different balance mechanisms, a mechanically connected taught band microbalance and a Magnetic Suspension Balance offering a unique hermetically sealed reactor for highly reactive gases.

A large range of reactors from -196°C to 1800°C and ultra-high vacuum to 350 bar are available. An optional TG-DSC Thermogravimetry – Differential Scanning Calorimetry measuring head allows the simultaneous determination of weight change and caloric reactions in one run.

Linseis offers the broadest range of Sorption Analyzers for numerous applications such as:

  • Gas Sorption
  • Vapor Sorption
  • Mixed Gas Sorption
