Sample Preparation for Particle Size Analysis of Submicron Powders.

Successful Particle Size Analysis of Dry Powders

A correctly set up dry powder measurement using a laser diffraction particle size analyser is much easier to perform than measurement of wet suspensions. However, incorrect measurement set-up can lead to errors and inconsistencies. This article examines the key steps achieving successful dry to powder measurement. Issues examined include powder flowability and sampling, air pressure and sample ...

A new method for the preparation of pure topiramate with a micron particle size

Crude topiramate was prepared from the reaction between diacetonefructopyranose, sulfuric diamide, and 2-picoline. During a controlled processing the presence of Triton-X-100, crude topiramate in a methanol-water solvent, was converted to pure micron size topiramate particles. The factors affecting the purification and micronization of topiramate, such as solvent and anti-solvent type and conce...

Effect of Particle Size on Detergent Powders Flowability and Tabletability

Detergent powders are sometimes processed into compact tablets for cleaning purposes based on the advantage of dosage, minimised dusting and packaging its offers over their powder counterpart. The flow-ability greatly influences handling. The particle size within the powder plays a key role on handling, flow-ability and the strength of the produced compact detergent tablet. The Ariel powder use...
