LAR Process Analysers has introduced the QuickCOD analyser, which provides online COD (chemical oxygen demand) determination.
QuickCOD can determine COD in one minute without reagents.
It is suitable for COD applications in industrial and municipal waste-water treatment and is DIN-standard compliant.
Typical online applications range from early warning of high oxygen demand influences (from detection of organic spills and product loss) to effluent monitoring in chemical, petrochemical and food-processing plants.
The COD measurement can be performed in high salt concentrations (more than 20g/l) without memory effects; this makes the QuickCOD ideal for applications with concentrations that change within minutes.
A dilution of the sample is not necessary.
The analyser guarantees the complete digestion of all organics by subjecting the sample to high-temperature combustion at 1200C.
It requires no reagents and no caustics or other dangerous substances.
This results in a reliable and easy to use instrument.
The QuickCOD can support on-line analytics and laboratory tests.
It works with the Flowsampler sample-preparation system, which is filtration-free.
The QuickCOD's sample can be homogenised if required, allowing the COD to be quickly determined.
