Hach BioTector B3500dw TOC Analyser

The Hach BioTector B3500dw TOC Analyser is the most comprehensive unit to measure TOC in municipal drinking water and potable water. The uptime of the unit and continual readings provide customers with the best option for the operation of a drinking water facility. EPA method approved.

Rock solid reliability:

With patented, EPA method approved Two Stage Advanced Oxidation Technology, the self-cleaning sample reactor of the B3500dw delivers maximum reliability.

Lowest cost of ownership:

With its 99.86% uptime, semi-annual maintenance and reagent replenishment is all that is needed.

Secure your source water:

TSAO technology analyses organics in your source that are
invisible to scanning UV technologies.

Principle of Operation

  • TIC

    Acid is added to lower the pH so that inorganic carbon is sparged off as CO2.
    This is measured to ensure Total Inorganic Carbon (TIC) is not carried over into the TOC.

  • Oxidation

    BioTector’s patented oxidation method (TSAO) achieves total and complete oxidation of the sample, including organic carbon to CO2. TSAO utilises hydroxyl radicals generated within the analyser by combining oxygen, which passes through the ozone generator, with sodium hydroxide.
