Chromatography

Chromatography is a lab technique used to separate and identify components within a sample based on chemical or physical properties. Chromatography techniques such as gas chromatography and liquid chromatography are powerful tools for small molecule analysis in labs conducting drug impurity analysis, drug discovery, or pharmaceutical stability testing. In this hub, you can explore the latest chromatography tools and techniques available to pharmaceutical researchers, read expert advice and explore industry best practices.

Comparison of Optical Spectroscopy Techniques for Pharmaceutical Analysis

CIP Failures Due to Biofilm Formation: Strategies for Prevention and Remediation
The aim of a Clean-in-Place (CIP) system is to remove all undesirable materials from product contact surfaces to a level such that residues remaining are of minimal risk to the safety or quality of the product. While the general focus is on the removal of product residues or chemical residues, there is often a microbial control element involved. ... read more
Comparing an Inspection by a Regulator to an Investigation by a Pharma Company
Recently, there has been an increased focus on contamination control activities for pharmaceuticals due to updated requirements in the European Union’s Annex 1 Update. (EU, 2022). The recent update of Annex 1 (ISO 14644-1, 2022) has specified the need for a contamination control strategy for both sterile and non-sterile products. Recently, a ... read more
