AQF-2100V

High-Precision Sulfur & Halogen Analysis for Liquid and Gas Samples

The Nittoseiko AQF-2100V is a high-performance vertical furnace unit designed specifically for combustion ion chromatography (C-IC). Engineered for fast, accurate and low-blank analysis of sulfur and halogens (F, Cl, Br, I), it provides a highly reliable solution for environmental labs, petrochemical applications, industrial QC, catalyst analysis, and research working with liquids, LPG and gas samples.

Featuring direct sample injection, low-blank gas control, multi-element capability, and optional automation modules, the AQF-2100V delivers superior trace-level analytical performance in a compact, easy-to-operate system.

Key Features & Advantages

⚡ FAST – No Boat Program Required

• Direct, fully automatic sample introduction for liquid, LPG and gas samples
• No boat, tray or combustion program needed
• Multiple injections possible for large-volume samples

→ Results in significantly reduced analysis time and simplified workflows

🎯 ACCURATE – Low System Blank & High Purity Combustion

• Direct injection into the vertical heater furnace minimizes contamination
• Newly designed low-blank gas control unit
• High-purity quartz combustion tube ensures stable, precise pyrolysis
• Ideal for trace-level F, Cl, Br, and S determination

🧪 Multi-Element Measurement in One Combustion

The system supports simultaneous quantification of:

Fluorine (F), Chlorine (Cl), Bromine (Br), and Sulfur (S)

→ Reduced sample usage, reduced run time, improved efficiency

👨‍🔧 EASY – Simple, Safe & User-Friendly Operation
