Wide-range TOC with sensitive NDIR detection
UV oxidation of organic carbon compounds in aqueous samples to carbon dioxide (CO₂). The generated CO₂ is quantified using a highly sensitive NDIR detector, ensuring excellent detection limits and measurement stability. The system supports reagent-free operation for TOC levels below 2000 ppb, and operation with reagent for higher TOC concentrations and less-oxidative substances, depending on the application.
Configure the flexiTOC for your process
Multiline mode
The flexiTOC pro provides 4 inlets; a software upgrade lets you measure up to 3 loops sequentially, configuring each interval separately.
Sample mode
A sample-mode configuration measures separate samples offline; the sequence is user-customizable.
Calibration & verification
Reagent and water-blank determination plus multipoint calibration with internal standard dilution for enhanced analytical accuracy.
Data export
Export to external storage in various formats; cloud storage via network, and sharing with customer service for error diagnosis.
System status
A complete software overhaul delivers a detailed status overview, including operating hours for individual sensors, a pump, and the UV lamp.
Heat exchanger
Required for medium temperatures above 50 °C.
Pressure regulator
A pressure transducer is required if the incoming medium pressure exceeds 0.5 bar.
21 CFR Part 11 software
Conformity for pharma applications — secure data handling, electronic records and signatures.
IP54 housing
Screen and fan supplied with IP54 protection as standard.
Reagent-free & reagent modes
The flexiTOC runs reagent-free for TOC levels below 2000 ppb, and switches to reagent operation for higher TOC concentrations and less-oxidative substances — covering a wide application range from tap water to demanding samples.
