Overview
A lined anti-corrosion chromatography column is a specialized separation device designed for harsh chemical environments. It features a stainless steel core with an internal PTFE or PFA lining to ensure inertness and resistance to aggressive solvents. Manufactured under strict industrial standards, these columns maintain structural integrity while preventing sample contamination during analysis.
Application
- Petrochemical Industry: Monitoring corrosion inhibitors and fuel additives in high-acidity streams.
- Pharmaceuticals: Analyzing active ingredients where metal ion interference must be eliminated.
- Environmental Testing: Detecting trace pollutants in wastewater containing strong oxidizers.
- Food & Beverage: Quality control of acidic products like fruit juices and vinegar.
Precautions
- Operate within specified temperature and pressure limits to prevent liner deformation.
- Conduct periodic visual inspections for cracks or delamination in the lining layer.
- Replace units immediately if seal failure occurs to avoid cross-contamination.
- Clean thoroughly with compatible solvents after exposure to corrosive reagents.
