What is DVS Carbon? 

The latest addition to the DVS product family, the DVS Carbon is the first gravimetric sorption analyzer specifically built for advanced Carbon Capture, Utilization and Storage (CCUS) applications.

In most gas-phase carbon capture applications, CO₂ often competes with other chemical species present at the sorbent site — including water vapor. The new DVS Carbon enables measurement of CO₂ uptake under real-world conditions by controlling both temperature and humidity across a broad range of CO₂ concentrations.

Using the patented Surface Measurement Systems UltraBalance to measure mass changes from sample sorption and desorption in real time, the DVS Carbon allows for the evaluation of complex carbon capture conditions across a wide variety of materials. The system can also be configured to enable additional functions as needed.

01

A First-of-Its-Kind Innovation 

The DVS Carbon is the first gravimetric sorption analyzer specifically designed for advanced carbon capture conditions in this rapidly growing research field.

02

Independent Multi-Component Control 

Through a precisely calibrated mixing system, the DVS Carbon allows independent control of CO₂ and water concentrations. By precisely regulating variations in both concentration and temperature, it enables the design of complex sorption experimental programs. 

03

CO₂ and H₂O Isotherm Analysis with Kinetic Performance 

Measures CO₂ and water isotherms of samples under real-world conditions. The sorption kinetics at each step can be automatically verified through the dedicated control and analysis software included with the system. 

04

Experiments Across Multiple Concentration and Temperature Ranges 

CO₂ concentration control from high levels (%) down to the ppm range makes the DVS Carbon suitable for DAC, PCC, and other CCUS applications.

• DAC (Direct Air Capture)
• PCC (Post-Combustion Capture)
• CCUS (Carbon Capture, Utilization and Storage)

05

In-Situ Activation and Regeneration 

When the instrument's capabilities are extended with the pre-heater, samples can be locally heated up to 300 °C under inert or process gas, enabling direct determination of drying activation or decomposition reaction kinetics.
