Physical characteristics determined include:
Particle size
Surface area
Pore volume, Pore size and Pore size distribution
Absolute density, Envelope density, and Bulk density
Catalytic activity, Active surface area, and Strength of adsorption sites

Micromeritics also operates Micromeritics Analytical Services, a full service particle testing laboratory that provides sample analyses on a contract basis. Working in conjunction with Micromeritics Analytical Services is the European Micromeritics Analytical Services group.

With U.S. corporate headquarters in Norcross (Atlanta), Georgia, Micromeritics has an extensive worldwide sales and service network.
