Measurement and Quantification of Caking in Powders

  Many powders have the potential to cake during storage. As the strength of particle-particle interactions increases, especially via mechanisms involving moisture, the flow characteristics of the material are compromised, detrimentally impacting performance and value. Caking may be preventable or easily addressed through the adoption of well-defined protocols, for example, storing the material in a…

Sample Preparation and the Impact on Results

  Sample preparation is an often-overlooked part of the material analysis process, yet it is critical to achieving consistent and high-quality results. This webinar will discuss the importance of sample preparation and different methods for activating samples. Emphasis will be placed on activating samples for analysis in physisorption and chemisorption instruments. Particle size and methods…

TPR of Copper Oxide Nanoparticles on Alumina ‚Äď Understanding the Effects of Particle Size and Surface Chemistry

  TPR studies are often repeatable, but a change in the experimental conditions or preparation of the material can affect the results. Due to this complexity, experimental conditions are selected based on models such as Monti and Baiker ‚Äď which considers the selection based on the heating rate, hydrogen concentration, total flow rate, and the…
