How to Verify Light Exposure Uniformity in Chambers for Photostability Testing
Verifying the uniformity of light exposure in photostability testing chambers is essential for generating valid, reproducible data. Regulatory authorities such as the USFDA and ICH Q1B guideline emphasize the need for consistent and homogenous illumination during forced degradation and stability trials. This tutorial outlines how to verify light distribution across the testing zone, the equipment…
