TNM-1 - Total Nitrogen Measuring Unit

TN Unit



  • Combustion tube and oxidation catalyst are shared with TOC analysis, such that maintenance is virtually identical to dedicated TOC use. Maintenance is simple as no oxidant or other reagent is required.
  • NO2 (nitrogen dioxide) is measured by Shimadzu's tried and tested chemiluminescence method.
  • Measurements over a wide range from 0.1 mg/L to 4000 mg/L.
