Some published articles purport to demonstrate the difficulties and problems of the laser diffraction technique without mentioning that these apparent problems are inherent in all particle-sizing techniques. This article discusses some of the advantages of using laser diffraction for particle sizing-including repeatability, ease of verification, and speed of measurement-and why it has become the preferred technique in a range of industries.

This article outlines a comprehensive approach for organizing a firm's aseptic operations, including planning for routine and nonroutine interventions, establishing effective process simulations, and determining which vials to incubate.

As newer and more elaborate hardware and software systems are installed in automated manufacturing environments, companies are further incorporating good practices into their validation process.
