NSX-5000V

High-Sensitivity Analysis of Nitrogen, Sulfur & Chlorine in Liquids and Gases

The NSX-5000V series from Nittoseiko is an advanced trace elemental analysis platform engineered for ultra-sensitive and automated quantification of nitrogen (N), sulfur (S) and chlorine (Cl) in both liquid and gas samples. Built around a unique openable vertical furnace system, it delivers maximum operational safety, reduced environmental impact and exceptional analytical performance.

Designed for laboratories in petrochemicals, chemicals, recycled fuels, automotive fuels, and environmental monitoring, the NSX-5000V offers rapid, precise and reproducible analysis while minimizing gas consumption, waste generation and maintenance complexity.

Key Features & Advantages

🔄 Automatic Syringe Dilution (ASC-550L)

Accurate, fully automated dilution independent of operator skill.

• Eliminates manual dilution errors
• No need to pre-prepare calibration curves
• Reduces waste solution → lower environmental burden and running costs

🖥️ User-Friendly Software Interface

Two operation modes:

• Simple Mode – intuitive operation for routine QC and daily lab workflows
• Advanced Mode – full configuration access, audit trail viewing, data management

💲 Low Running Cost

• Significantly reduced gas consumption compared to previous models
• Automatic gas shut-off after each measurement to minimize consumption

🛠️ Easy Daily Maintenance

The innovative open/close vertical furnace enables:

• Quick access for inspection
• Easy pyrolysis tube replacement
• Simple visual checks of furnace conditions

🔐 Compliance, Security & Audit Functionality

• Full Audit Trail: all operations logged for regulatory audits
• User Management with 3 login levels: protects methods and data
• Reanalysis function: correct measurement start/end time after run if needed
