With the years of experiences on process analysis and environmental monitoring instrument development, the Focused Photonics develops the COD-2000 series COD Online Analyzer which is a new generation in the world. Such analyzer applies advanced sequence injection platform, and combines with national standard detection method, so it can provide reliable, accurate COD monitoring results.
- It adopts the sequence injection platform which is advanced in the world.
- Innovative structure of liquid storage ring, the sample or reagent never touches directly the injector, for avoiding the abrasion and corrosion of injection flow path.
- The flow path of valve head adopts the laser micro-machining technology, which can control precisely the dimension and position of notch groove, ensure that the flow path will be with no dead volume when the valve position shifts, thus guarantee that there will be no residual reagent.
