Introduction: The chemical oxygen demand CODcr is an important detection index for judging water pollution sources. The detection method generally adopts the dichromate method. This method is used as the standard for environmental law enforcement, but the analysis process requires personnel to add concentrated acid reagents. The dangers and reagents of this process The uncertainty of accuracy is greatly increased; the temperature of the digestion heat source is not balanced, the consistency of the sample digestion process cannot be well controlled, and other drawbacks, which lead to the failure to improve the experimental efficiency and accuracy of the data support. The Shunxin 1500 automatic CODcr analyzer integrates the microcrystalline carbon fiber radiation heating unit, the double-robot quantitative addition unit, the automatic docking unit for the digestion and condensation container, and the automatic titration unit to realize the unattended operation of the entire analysis process, which improves The parallel consistency and data accuracy of the experimental data reduce the risk of concentrated acid corrosion in the experimental process and ensure safe, accurate and effective operation and analysis. It is suitable for automatic digestion titration analysis of chemical oxygen demand in surface water, industrial wastewater and domestic sewage. Features: 20 sample channels, unattended analysis of multi-channel samples; Double robot arms, realize the addition of quantitative reagents in the digestion bottle and the condensate bottle respectively, which conforms to the national standard method; Powerful function mode, high and low concentration sample measurement mode at the same time, full color gamut color automatic titration analysis mode; The digestion bottle and the condensate bottle are intelligently separated and coordinated, and the multi-angle spherical sand core is sealed; Circulating water is condensed, the condensation is more sufficient, continuous digestion analysis, not affected by the environment, heating and other temperature; Safe protection operation, automatic identification of digested samples, no reagent protection without bottles. technical parameter: Sample channel: 20-bit channel Reagent pipeline: independent 8 channels Titration range: high concentration (50-700) mg/L Low concentration (16-50) mg/L RSD: 2% Detection limit: <4mg/L
