Unraveling Hierarchical Pore Networks Using Differential High-Resolution Mercury Intrusion

The void structure of porous materials used as catalyst supports affects several properties such as permeability to liquids, gas diffusion, organic molecules access, availability of oxidation/reduction active sites, and so forth. Mercury intrusion porosimetry has been widely used to investigate the accessible pore volume starting from about 3.6 nm up to more than 600 µm. […]

Maximize Your Results from the Micromeritics AutoPore V – Demonstration

In this webinar, Tony Thornton, Micromeritics Director of Technical Information, will lead you through a brief demonstration of the AutoPore, from loading a sample in a penetrometer, through low and high pressure analysis, and pore size distribution analysis review. The AutoPore V series determines pore volume and pore area distributions as a function of pore […]

Porosity and Density Characterization of Freeze-Dried Organic Products: Case Study of Instant Coffee

The freeze-drying procedure is a common technique used in the food industry to dehydrate organic compounds. The technique, also known as lyophilization or cryodesiccation, is a method of food preservation by removing water content. Once the organic compound comes into contact with water again, it will resume its original properties such as consistency, taste, etc. […]

Unified Approach to Understanding Porous Materials

This webinar presents a generalized approach to modeling the pore size distribution which has been developed to determine the complete distribution of macro-, meso-, and micro-pores.Rather than using a fragmented approach of simple overlays from individual techniques, the Unified Method provides a full pore size distribution and improved estimate of total pore volume of the […]

Physical Characterization Methods for Cathode Powders

Anytime a powder is used in a process for a specific purpose, its behavior is often predicted by physical properties of the powder.  Determining the physical properties of a cathode powder can be used to decide which properties are critical to the performance of the cathode, as well as the battery in which it is used.  A sample of lithium iron phosphate (LFP) powder was characterized to determine […]

AutoPore V

Measures density, in addition to full porosimetry, especially for meso- and macro-porous materials.
