The Importance of Moisture Content Testing | Karl Fischer Moisture Analyzers in the Pharmaceutical Industry

Pharmaceuticals are a special commodity whose quality bears directly on human life and health; strict production quality control safeguards drug quality and medication safety, and the strict FDA/GMP requirements of the 2017 Pharmacopoeia raise the bar for drug quality testing.

In pharmaceutical production, moisture is a key quality indicator affecting product quality and shelf life; it must be strictly controlled and tested throughout production and quality control.

The Karl Fischer method is the most-used moisture method in pharmaceuticals. Samples vary widely in form—tablets, suppositories, freeze-dried preparations, active substances—with free water, crystallization water, and active ingredients all affecting measurement, so solvents and reagents must be chosen per each drug's properties.
