Sample Preparation for Gas Pycnometry

A gas pycnometer determines the volume of a material by measuring the pressure change of an inert gas within two calibrated volumes. Density is calculated from the measured volume along with the mass of the sample. Prior to analyzing, the gas pycnometer purges the sample with an inert gas to clean atmospheric gases, such as […]

A Novel Scale-Down Agitated Filter Bed Dryer for Evaluating Crystal Breakage in the Pharmaceutical Industry

Crystalline products are widely used in the pharmaceutical industry as active pharmaceutical ingredients (APIs). However, these products are often susceptible to mechanical damage during isolation and drying processes, such as agitated filter bed drying (AFBD). AFBD involves the use of an impeller to promote uniform drying of the wet cake by intermittent agitation. However, the […]

Building Robust Pharma Physical Properties Analysis

Broaden your understanding of solid form analysis. Traditionally a limited number of techniques have been used for physical properties analysis. Now, the opposite is becoming the issue, there are a multitude of good and reliable techniques, that can enrich solid form analysis. By looking at examples of porosity, surface area and powder flow analyses, we […]

Understanding Density Measurement Techniques

A critical attribute that contributes to the quality of a manufacturing process is the density of the powdered or solid material.  Density gives information about the amount of material in a given volume which can offer a prediction of how the powdered material will pack.  Density also gives information on the amount of hollow cavities […]

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 […]
