One of the most important skills any editor must possess is the ability to listen to their audience — without feedback, we don't get an opportunity to develop our publications; to not act on feedback shows plain ignorance. I must, therefore, give my personal thanks to the many hundreds of readers who participated in the Pharmaceutical Technology Europe (PTE) editorial and readership survey, which we conducted earlier this summer. Your comments and opinions will help us develop PTE, and we already have a number of exciting plans for 2006. Stay tuned!
In-process methods are key components of quality control in a chemical manufacturing plant. These methods ensure that a production reaction step conducted by trained operators within the entire validated process will produce a quality chemical entity in the expected yields. The presence of impurities and related compounds (derived from the reaction or secondary reactions) is a critical parameter that determines a synthetic material's quality.
Chemical purity is the most important quality characteristic of a pharmaceutical substance. This article describes the latest scientific and technological advances to meet recent pharmacopoeial and regulatory requirements regarding the control of organic impurities in synthetically produced active substances. Future developments and suggestions for those working in quality control and raw material selection are discussed.
Dust extraction and centralized vacuum cleaning systems vary in their design, performance and costs. Different companies have different approaches to their design, however, there are some basic rules that must be followed if these systems are going to be immediately effective and avoid future problems.
