Micromeritics, a manufacturer of particle and nanotechnology instruments and equipment, is offering a free materials characterization workshop and plant tour on March 15, 2011, at its headquarters located in Norcross, Ga. The company says the workshop will benefit scientists, laboratory supervisors and technicians in industry and academia where knowledge of the physical characteristics of powders and solids is essential.
Three presentations are being given by Micromeritics staff scientists. The presentations will conclude with a question and answer session. The sessions will be followed by a tour of the company’s manufacturing facility.
- Determination of Particle Size Distribution of Powders by Various Analytical Methods, Including Characterization of Particle Shape – led by Anthony Thornton, director of Product Integrity and Performance
Six methods, including one for characterizing shape of particles, will be discussed. A description of each method, including the principle of operation, data reduction and reporting and advantages and applications, will be provided. Methods to be discussed are X-ray monitored gravity sedimentation, static laser light scattering, dynamic laser light scattering, electrical sensing zone, air permeability and dynamic image analysis.
- An Examination of Chemisorption – A Powerful Tool Widely Used in the Study and Characterization of Catalysts – led by Simon Yunes, senior application scientist
Chemical adsorption analyses can provide much of the information needed to evaluate catalyst materials in the design and production phases, as well as after a period of use. The chemical adsorption isotherm reveals information about the active surface of a material and researchers have used if for many years as a standard analytical tool for the evaluation of catalysts. In addition, thermo-programmed techniques have emerged as an indispensible companion to chemisorption isotherm analyses.
- Physical Adsorption – A Powerful Technique for Determining the Surface and Pore Structure of Solids – led by Jeff Kenvin, group leader of the Scientific Services Group and Jacek Jagiello, senior scientist
This seminar will compare traditional techniques for surface area and pore structure to modern techniques including the use of non-local density functional theory and statistical mechanics. Additional topics will also include the use high pressure adsorption and the determination of the heat of adsorption for adsorbents.
