NSX-5000H

High-Precision Measurement of Nitrogen, Sulfur & Chlorine in Liquid and Solid Samples

The NSX-5000H series from Nittoseiko is an advanced horizontal-furnace trace elemental analyzer designed for fully automated, safe, and ultra-sensitive quantification of nitrogen (N), sulfur (S) and chlorine (Cl) in liquid (non-aqueous) and solid samples. Engineered to support environmental sustainability through reduced gas consumption and optimized workflows, it delivers robust analytical performance for routine QC and high-level research laboratories.

Ideal for the petroleum, chemical, recycled fuels, automotive, and environmental analysis sectors, the NSX-5000H offers exceptional reproducibility, fast measurement cycles and simplified operation.

Key Features & Advantages

🖥️ User-Friendly Software

Two operation modes ensure accessibility for all experience levels:

• Simple Mode – for routine QC and fast everyday operation
• Advanced Mode – for detailed method creation, audit trail review and system configuration

🚀 Rapid Analysis with Automatic Sample Boat Control

The analyzer automatically introduces the sample boat into the furnace with precisely controlled speed, preventing incomplete combustion and ensuring:

• Stable, reproducible combustion
• Shorter measurement times
• Accurate trace-level detection

New measurement programs can be created quickly and easily.

💲 Low Operating Cost

• Reduced gas consumption compared to previous models
• Automatic gas shut-off after measurement

→ Lower environmental load and reduced running costs

🛠️ Easy Daily Maintenance

The open/close horizontal furnace design enables:

• Quick visual inspection of pyrolysis tube condition
• Easy replacement of components
• Simplified routine maintenance

🔐 Compliance, Data Integrity & Automation

• Audit Trail – complete logging of all operations for regulatory compliance
• User Management (3 access levels) – prevents unintended edits to methods or data
• Automatic Start-Up / Shut-Down – fully programmable temperature and gas-flow sequences
• Reanalysis Function – adjust measurement start/end time after acquisition
