Knowledge Base

Q

This article analyzes the common models and functional characteristics of COD heating reflux digesters, compares them comprehensively from basic to intelligent models, helps laboratory personnel choose suitable equipment according to their needs, and shares usage and maintenance skills.

Q

As a key indicator for measuring the relative content of organic matter in water bodies, chemical oxygen demand (COD) plays a crucial role in water pollution monitoring and control. It not only reflects the overall level of organic pollutants in water bodies, but also serves as an important basis for evaluating water quality and formulating water pollution control measures. However, the measurement process of COD is not smooth sailing, and its accuracy is often compromised

Q

The use of glass burr reflux pipes instead of spherical reflux pipes, and the use of air cooling technology instead of tap water reflux cooling, with static water assisting cooling at the end of the condenser pipe, 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 are fully in accordance with HJ828/2017
