Surface Measurement Systems – DVS Carbon
The latest addition to the DVS family, DVS Carbon, is the first purpose-built gravimetric sorption analyzer for advanced carbon capture, utilization, and storage (CCUS) applications. In most gas phase carbon capture applications, CO2Â often competes with other chemical species at adsorbent sites, including water vapor. The new DVS Carbon enables the measurement of CO2Â uptake in real life conditions, controlling both temperature and humidity at a broad range of CO2Â concentrations.
With the patented Surface Measurement Systems Ultrabalance measuring real-time mass changes caused by sorption and desorption in the sample, complex carbon capture conditions can be assessed in a range of materials. In addition, the system can be configured to enable a range of different capabilities.
