TOC Analyzers
TOC-VWS: Wet oxidation/NDIR method, standalone
TOC-VWP: Wet oxidation/NDIR method, PC-controlled
Shimadzu is proud to introduce the first Heated-UV-Persulfate system that utilizes three oxidation methods for maximum oxidation efficiency. This method ensures rapid, efficient breakdown of hard-to-oxidize compounds up to 1.6 mm in diameter. The TOC-VW is the most powerful wet chemical TOC on the market, capable of measuring down to 0.5 ppb of TOC and up to 3000 ppm.
Features
- 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.
- 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
CLASS-Agent Software Meets All 21 CFR Part 11 Requirements
