Here’s a more detailed look:
- Why metal detection is essential: Metal fragments in medications can cause serious harm, including digestive problems, tissue damage, or even life-threatening complications.
- How metal detector tubes work: They use electromagnetic induction to detect metal objects by disrupting the normal electromagnetic field when a metal particle passes through.
- Contamination sources: Manufacturing equipment:Friction and wear of equipment like mixers, mills, and tablet presses can generate metal particles.
- Raw materials:Some raw materials, like certain metals or their residues in packaging, can introduce metal contaminants.
- Types of metal detectors: Pharmaceutical metal detectors are specialized for detecting and rejecting contaminated products, often equipped with quick-acting reject gates.
- FDA requirements: The FDA has specific guidelines for metal detection in pharmaceutical products, including critical limits for acceptable metal sizes.
- Sensitivity and precision: Pharmaceutical metal detectors are designed to detect very small metal fragments, with sensitivities reaching 0.5 mm for stainless steel and 0.3 mm for ferrous metals.
