First-of-its-Kind

In this growing research space, the carbon dioxide analyzer, DVS Carbon is the first purpose-built gravimetric sorption analyzer for advanced carbon capture conditions.

Independent Multicomponent Control

With a carefully calibrated mixing system, the DVS Carbon independently controls the CO₂ and water concentration, enabling complex sorption programs to be created with controlled changes in concentration and temperature.

Isotherms of CO₂ & H₂O

Test your materials to get CO₂ & water isotherms in realistic conditions, with kinetics for each step available by default with our purpose-built control & analysis software.

Multiple Concentration and Temerature Ranges

High (%) or low range (ppm) CO₂ can be controlled, suitable for DAC, PCC, or other CCUS conditions.

In-situ Activation & Regeneration

Expanding your instrument capabilities with a pre-heater, your sample can be locally heated up to 300 ^oC under inert or process gas, with drying activation or segmentation kinetics determined directly.
