Biochar Characterization and Micromeritics Analytical Services
The biochar community is looking for characterization methods in order to match the biochar and soil that will achieve the most beneficial and desired effect.
Norcross, GA - 10/14/2009 -- Micromeritics Analytical Services (MAS) recently co-authored a paper presented at the North American BioChar meeting (link) held in Boulder, CO August 9-12, which demonstrated the use of gas adsorption combined with mercury porosimetry to get a full pore size analysis of biochars. Also examined was the breakdown of this material after multiple freeze-thaw cycles to determine what changes might occur in the particle size, surface area, and pore size distribution. These techniques complement one another and are very useful in providing a clearer picture of the pore structure and sample capabilities. MAS provides many physical characterization measurements including BET surface area, pore size analysis by both gas adsorption and mercury porosimetry, CO2 adsorption isotherms, water vapor adsorption isotherms, bulk density, true density, and particle size analysis.
