Precise, low-level TOC measurement that you can trust
Changes in water quality for ultra pure applications are disruptive to plant operations. Accurate, on-line analysis is important to protect critical equipment that depends on ultra pure water resources. Leading manufacturers know that it is critical to analyse for contaminates precisely at ppb levels to maintain water quality. Reliability and effective oxidation of large samples ensures that manufacturers can trust the results reported by the BioTector B3500ul analyzer. With a full picture of organic contaminants in critical water applications manufacturers make water treatment decisions more efficiently. The Hach® BioTector B3500ul provides reliable and accurate TOC analysis at ppb levels for ultrapure water applications. The patented two stage advanced oxidation technology behind the BioTector thoroughly, and reliably oxidizes samples for valuable real-time water analysis.
Key advantages
- Maximum uptime for your process
- Instant and long term savings
Principle of Operation
TIC
Acid is added to lower the pH so that inorganic carbon is sparged off as CO2. This is also measured to ensure the Total Inorganic Carbon (TIC) is not carried over into the TOC.
Oxidation
BioTectors’s patented oxidation method (TSAO) efficiently oxidizes the organic carbon in the sample to CO2. TSAO utilizes hydroxyl radicals generated within the analyzer by combining oxygen, which passes through the ozone generator, with sodium hydroxide.
TOC
To remove CO2 from the oxidized sample, the pH of the sample is lowered again. The CO2 is sparged and measured by the specially developed NDIR CO2 analyzer. The result is displayed as Total Organic Carbon (TOC).
