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 […]

Best Practice for BET Surface Area

The specific surface area of a material, often referred to as BET surface area, is an important parameter throughout all kinds of industries. Whether it is in the field of adsorbents, additive manufacturing, pharmaceuticals, or catalyst research, this parameter helps in quality control, to optimize processes, and improve material performance. Even though the determination of […]

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 […]

Rapid & Precise Surface Area Analysis

The Measurement of Pharmaceutical Binders Using the TriStar II Krypton Option

The TriStar II’s Krypton Option can measure materials with surface areas as low as 0.001 m2/g and is ideal for difficult-to-measure pharmaceutical binders. Pharmaceutical binders such as micro-crystalline methylcellulose (MMC), lactose, and gelatin typically have surfaces areas under 2 m2/g and, therefore, are perfect candidates for krypton adsorption with the Tristar II analyzer. Advantages of […]

The Measurement of Pharmaceutical Lubricants Using the Tristar II Krypton Option

A major advantage for using the TriStar II with the Krypton Option is the ability to measure low surface areas. Although the TriStar II standard nitrogen system can measure surface areas as low as 0.01 m2/g, the Krypton Option enables you to measure areas as low as 0.001 m2/g and provides increased accuracy for materials […]

Performance Testing Porous Aluminas Using the TriStar Surface Area and Porosity Analyzer

This application note explains what aluminas are, their use as a vapor trap, and how a BET surface area measurement can be used as an indicator for their performance. Alumina is more correctly known as aluminum III oxide. Porous aluminas are produced from sintering the material at elevated temperatures; alumina in a pellet form is […]
