Linseis – Gravimetric Sorption Analysis (GSA)
Integrated solutions that offer the possibility to control the pressure, temperature and gas dosing independently of each other using the supplied software.
Linseis offers two different load cells, a mechanical microbalance and a magnetic levitation balance.
The magnetic levitation balance offers a unique, hermetically sealed measuring cell for highly reactive gases.
There is therefore a large selection of available devices in a temperature range from -196 °C to 2400 °C and a pressure range from ultra-high vacuum to 350 bar.
An optional TG-DSC (Thermogravimetry – Differential Scanning Calorimetry) measuring head enables the simultaneous determination of weight changes and caloric reactions in one measuring run.
