TOC-VW Wet Chemical Total Organic Carbon Analyzers

Rapid Breakdown of Difficult-to-Oxidize Compounds

Wet Chemical Total Organic Carbon Analyzers

TOC-VWS: Wet oxidation/NDIR method, standalone
TOC-VWP: Wet oxidation/NDIR method, PC-controlled

Shimadzu’s TOC-VW can be operated as a UV/Persulfate TOC, a Heated/Persulfate TOC, or as a unique Heated-UV-Persulfate TOC system. The three oxidation methods ensure rapid breakdown of difficult-to-oxidize compounds up to 1.6 mm in diameter and and shorter analysis time. The most powerful wet chemical TOC on the market, it is capable of measuring down to 0.5 ppb of TOC and up to 3000 ppm.


  • Newly designed high-sensitivity NDIR detector - achieves ultra-high sensitivity measurements, eliminates false peaks, and contains 5 orders of magnitude linearity
  • Sensitivity and accuracy enhanced by minimizing the reagent blanks that hinder accurate analysis.
  • Over-range samples can be compared with up to three calibration curves automatically
  • Powerful oxidation through a combination of peroxosulfuric acid, UV illumination, and heating.
  • No need for purging of reagent bottle reduces consumption of carrier gas.
  • Random-access autosampler control
  • Multipoint calibration curves in user-selectable concentration
  • Each sample can be automatically compared
  • Sample and standard peak profiles can be viewed
