Surface Area Pore V o l u m e , Size or Chemisorption Archaeological Chemistry II Advances in Chemistry Series No. 171 Giles F. Carter, Editor Eastern Michigan University A symposium sponsored by the Division of the History of Chemistry of the American Chemical Society. Beautifully illustrated with 15 color plates and printed on high-quality enameled stock, this book highlights the great strides that have been made in understanding the origin and distribution of archaeological specimens composed of pottery, glass, metal, bone, and pitch, through the unfolding of new and improved analytical techniques.
More R & D and QC labs worldwide use industry proven Micromeritics instruments to measure physical properties of materials than those of any other manufacturer. Micromeritics instruments reliably measure specific surface areas from 0.001 m2/g up, determine pore volume and pore size from 600 to 20Â diameter, and do chernisorption studies to determine catalyst activity. Both manual and automatic instruments are available. Micromeritics instruments use the classic, volumetric, gas adsorption (B.E.T.) technique employing a wide variety of adsorbates including argon, krypton, water vapor, nitrogen, or any non-corrosive gas.

Automated Measuring Saves Lab Time. If you measure viscosity with the capillary method, there's a SCHOTT AVS System for you. If you don't, maybe you should. The fully automated AVS/PA will test up to 30 different samples without operator supervision. Select the program and let it go! Variable program capabilities include: number of rinses, number of repeat measurements, test temperature, sample temperature conditioning period, suction rates and more. Standard-temperatures up to 150°C; High Temperature-up to 220°C. Measuring accuracy 0.1 % with a range up to 30,000cSt. Semi-Automated models also available. Building block concept allows expansion from basic unit to fully automated unit.
