Information

The GasPro is based on the Sievert’s method.A sample at known pressure and volume is connected to a reservoir of known volume and pressure through an isolation valve.Opening the isolation valve allows new equilibrium to be established. Gas sorption is determined by difference in actual measured pressure (Pf) versus calculated pressure (Pc).

Features

• Incomparable versatility: the GasPro operates from vacuum to high pressure (200 bar) on multiple volume gas doser (5 to 1200 ml) to tackle a wide variety of applications. Moreover the GasPro is designed to study sorption of a large choice of gases (Carbon Dioxide, Methane, Nitrogen, Argon, Hydrogen,…).
  
• Wide range of temperature: the GasPro covers a temperature range from -260 °C to 500 °C with different optional sample holders.
  
• Large variety of samples: the GasPro is designed to work on powders (CO2 storage materials, catalysts, MOFs), on fi bers (carbon), on thin films (food and pharmaceutical packagings, electronics), in liquids (CO2 capture solvents), coatings etc…
  
• Highly automated: automatic pressure range switching is available between high and low pressure transducers (from 0.001 to 200 bar).
  
• The GasPro software includes 15 automated processes for system preparation, sample preparation and 4 types of measurements (kinetics, PCT, cycling kinetics and cycling PCT).
  
• Portable equipment: the GasPro is portable and can be combined with other characterization techniques (X-Ray, neutron diffraction, calorimetry).
