Total Organic Carbon

Total organic carbon analyser measures total, organic/inorganic carbons and total nitrogen in soil and water samples.

Shimadzu TOC-L

The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation methode. While providing an ultra-wide range of 4 μg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 μg/L through coordination with NDIR. This is the highest level of detection sensitivity available with the combustion catalytic oxidation method. In addition, the combustion catalytic oxidation method makes it possible to efficiently oxidize not only easily-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds.


  • Capable of TC (total carbon), IC (inorganic carbon), TOC (= TC-IC), and TN (total nitrogen) measurements
  • The blank check function evaluates system blanks by measuring ultrapure water processed automatically within the instrument
  • The automatic dilution function enables measurements up to 30,000 mg/L
