Description
The Model 3S TOC analyzer measures total organic carbon in liquid samples using UV persulfate oxidation with carbon dioxide detection by nondispersive infrared absorption (NDIR). The sample is first acidified and then sparged to remove inorganic carbon. Sodium persulfate is then mixed with the remaining liquid and digested by two high performance reactors. The resulting carbon dioxide is stripped from the liquid and then measured by a NDIR analyzer. This method of TOC measurement conforms to EPA, DIN, CE, ASTM, and NAMUR regulations, and meets the requirements of ISO and EN directives.
Features & Benefits
- Measuring range: 0-5 mg/L to 20,000 mg/L
- Digitally controlled carrier gas flow
- Internal air compressor produces carrier gas for oxidation and detection. No need for external air treatment or compressed air supply like traditional analyzers
- Auto-cleaning system for the sample line and the external reservoir
- Minimal maintenance and long-lasting calibration
- Dual Compartment Enclosure – electronics separated from wetted parts of the analyzer
- Touchscreen interface
- Also available as a total carbon (TC) analyzer
