The PCTPro is a fully automated Sievert’s instrument for the measurement of gas sorption properties of different materials. With it’s ability to rapidly switch between gases and wide range of sample holders it is ideally suited for the fast growing field of Energy & Environment, specifically for the study of CCS (carbon capture and sequestration), methane sorption onto geological substrates, and porous solids characterization.


  • Incomparable versatility: the PCTPro 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 PCTPro is designed to study sorption of a large choice of gases (Carbon Dioxide, Methane, Nitrogen, Argon, Hydrogen,…).
  • Wide range of temperature: the PCTPro covers a temperature range from -260 °C to 500 °C with different optional sample holders.
  • Large variety of samples: the PCTPro is designed to work on powders (CO2 storage materials, catalysts, MOFs), on fibers (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 PCTPro 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 PCTPro is portable and can be combined with other characterization techniques (X-Ray, neutron diffraction, calorimetry).
