TOC-TNb Analyzer for Combined Carbon and Nitrogen

碳氮联用 TOC-TNb 分析仪

Treatment plants and environmental monitors reporting carbon and nitrogen loads can measure both from one injection. This TOC-TNb analyzer combusts at 720–800 °C, detects carbon by NDIR and nitrogen by chemiluminescence, covering 4 µg/L–30,000 mg/L carbon and 5 µg/L–10,000 mg/L nitrogen. Each sample takes about 4 min. Tell us typical concentrations.

Product Description 产品描述

Treatment plants and environmental monitors reporting carbon and nitrogen loads can measure both from one injection. This TOC-TNb analyzer combusts at 720–800 °C, detects carbon by NDIR and nitrogen by chemiluminescence, covering 4 µg/L–30,000 mg/L carbon and 5 µg/L–10,000 mg/L nitrogen. Each sample takes about 4 min. Tell us typical concentrations.

Highlights

  • Carbon and nitrogen from one sample injection
  • Chemiluminescence for selective nitrogen detection
  • Replaces separate total nitrogen digestion
  • Repeatability ≤2% for C and N at 10 mg/L

Applications

  • Wastewater treatment process control
  • Nutrient load assessment in rivers and lakes
  • Agricultural runoff monitoring
  • Fermentation and bioprocess media
