The GGC-10C COD intelligent digestion instrument follows the basic principles of standards (ISO) and standards (GB), ensuring the digestion operation of reflux heating and micro boiling for 2 hours, the preparation and addition of reagent solutions, and GB method * to ensure reliable analysis results.
This instrument uses microcomputer technology for time controlled heating and can simultaneously heat up six digestion conical flask reflux devices. To achieve the goals of energy conservation, reducing power load, and improving efficiency.
The instrument adopts a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water cooling. It can not only save water and standardize the instrument, but also improve the safety of instrument use.
The chemical solution preparation, operation, and COD calculation of the instrument fully comply with GB11914-89. COD water samples below 50mg/L can be improved by diluting titrants and oxidants, while COD samples above 1000mg/L can be determined by diluting the water sample proportionally.
