Metal Detection: Back To The Basics

Metal contaminants can enter pharmaceutical products through raw materials, processing equipment, or routine handling—making inspection a key safeguard for product quality and patient safety. Metal detection systems help identify ferrous, non-ferrous, and stainless steel contaminants in unpackaged products by creating a magnetic field around materials as they move through the line. When metal disrupts that field, the system can trigger an alarm or reject the affected product while allowing acceptable product to continue.

Strategically placed inspection points can help monitor APIs in powder form, processed tablets, and filled capsules where contamination risks may occur. With the right system, proper installation, and consistent operation and maintenance, manufacturers can reduce waste, limit downtime, support regulatory compliance, and strengthen process reliability.
