TOC Analyzer

Measuring TOC continuously online is the perfect solution
for monitoring contamination and discharges. The TOC
Analyzer measures total organic carbon in liquid samples
using the method of UV persulfate oxidation with
subsequent carbon dioxide detection by nondispersive
infrared absorption (NDIR). The analyzer can measure TOC
in liquid samples ranging from 0–5 mg/L to 20,000 mg/L.
The method conforms to EPA, DIN, CE, ASTM, and NAMUR
regulations as well as meeting the requirements of ISO and
EN directives

Analyte: Total Organic Carbon (TOC), Total Carbon (TC)

Method: For TOC measurements, inorganic carbon is removed by acidification and sparging;

this is followed by UV‐promoted persulfate oxidation. This process oxidizes the total

organic carbon into carbon dioxide which is measured in a nondispersive infrared

(NDIR) analyzer. For TC measurements, the sparging step is omitted
