AQF-5000H

High-Speed Combustion System for Sulfur & Halogen Analysis (F, Cl, Br, I)

The Nittoseiko AQF-5000H is a third-generation automatic quick furnace system engineered specifically for combustion ion chromatography (C-IC). Designed for unmatched speed, sensitivity and sample-handling flexibility, it enables highly accurate analysis of sulfur and halogens (fluoride, chloride, bromide, iodide) in both solid and liquid samples.

With advanced combustion control, optimized low-blank components, enhanced liquid-handling architecture, and optional automation modules, the AQF-5000H is a powerful, future-proof solution for environmental, industrial, petrochemical, electronic materials and regulatory laboratories.
