Micromeritics Instrument Corporation is an industry leader in particle science and particle technology. Micromeritics provides a complete line of scientific instruments and laboratory equipment targeted exclusively for areas of application and research involving particle science and particle technology, including the expanding area of nanoscience. Particle size analyzers employ laser diffraction, sedimentation and electrozone sensing. Physical adsorption and mercury porosimetry instruments determine surface area and porosity. Material density can be determined by gas pycnometry and solids displacement. Chemical adsorption techniques are used to determine the active area of catalysts, metal dispersion and surface energy. Pharmacology, cosmetics, nanotechnology, paints, pigments, food science, ceramics, textiles, geological science and polymer science are some of the areas of science and technology that rely on Micromeritics' instruments to determine the physical characteristics of powders and solid materials. Micromeritics was the first company to market commercially automated surface area, mercury penetration and sedimentation particle size analyzers. The company has also led the way in the areas of liquid chromatography, density, and automatic sample delivery. Micromeritics holds more than 40 patents in these combined areas of particle characterization. Micromeritics' corporate headquarters, manufacturing, research and development, and the Materials Analysis Laboratory are all located in Norcross, Ga.
