An Overview of Micron-Ranged Particle Sizing Techniques

INTRODUCTION Given the wide range of particle sizing technologies and instrumentation on the market, the choice of measurement technique can be daunting, especially if one is unfamiliar with the options available. Once introduced and familiar with an individual

Image Analysis

Blending of Log Normal Particle Size Distribution Data from Multiple Image Analyses Into Single Continuous Data Set

ABSTRACT Image analysis is one method by which particle size may be measured. In many cases, it is considered the “gold standard” of particle size measurement and is often used to verify the results of other techniques. Sample

Particle Shape Factors and Their Use in Image Analysis Part II: Practical Applications

ABSTRACT The first installment of this two-part discussion concluded by stating a single linear measurement (i.e., circular equivalent diameter) may not be adequate to describe a typical non-spherical particle with some degree of surface roughness. There are various

Particle Shape Factors and Their Use in Image Analysis – Part 1: Theory

ABSTRACT Fine particles are often characterized by their particle size and distribution as determined by various analytical instruments. Particle shape may be just as important as particle size. Particle shape, however, is often ignored or disregarded. Image analysis

Surface Area

The Importance of Sample Preparation When Measuring Specific Surface Area

ABSTRACT Specific surface area is a fundamental measurement in the field of fine particle characterization. Specific surface area measurements have numerous pharmaceutical manufacturing and quality applications. Compliance professionals should have a general understanding of the principles, procedures, and

Physical Measurement

Zeta Potential and Colloid Chemistry

ABSTRACT The US Food and Drug Administration often requests the measurement of zeta potential; however, there is virtually no guidance offered in any of the regulatory pharmacopoeias. Guidelines are available in other standards, and there exists a wealth

Particle Size

Particle Dispersion for Size Analysis

KEY POINTS The following key points are discussed: While particle size analysis can provide great insight in the pharmaceutical industry, it can be nearly meaningless if obtained improperly. A particle size distribution can be found for both colloidal
