1、 Product Description:

COD microwave digester is a pretreatment technology that combines high-pressure digestion and microwave rapid heating. After the mixture of water sample and acid absorbs microwave energy, the oxidation reaction activity of the acid increases, causing rapid chemical reactions of organic matter and other substances in the sample, in order to achieve the goal of rapid determination of water samples. The TC-100W COD microwave digestion instrument is designed based on relevant national standards and experimental foundations for the rapid determination of chemical oxygen consumption, total phosphorus, total nitrogen, and metal elements. It can be widely used for the determination of chemical oxygen consumption, total phosphorus, total nitrogen, and metal elements in surface water, groundwater, domestic sewage, and industrial wastewater.

2、 Technical features:

1. The experimental methods related to the TC-100W COD microwave digester are based on the "HJ/T 91 Technical Specifications for Monitoring Surface Water and Wastewater", "HJ/T 164 Technical Specifications for Monitoring Groundwater Environment", "Methods for Monitoring and Analyzing Water and Wastewater", etc

2. The TC-100W COD microwave digester uses 2450MHz electromagnetic waves as heating energy to generate high heat through high-speed wheel oscillation friction between water molecules, thereby achieving rapid heating and shortening digestion time.

3. The TC-100W COD microwave digester uses a PTFE sealed digestion tank for digestion,

The high temperature and high pressure during the digestion process can shorten the digestion time and suppress the influence of chloride ions on the reaction results; Adding an appropriate amount of mercuric sulfate can be used to measure the chemical oxygen consumption of high chlorine wastewater.

4. There is no need for cooling water during the digestion process, and there is a buzzing prompt after digestion is completed, which is convenient for experimental operation.

5. After digestion, the chemical oxygen consumption can be determined by potassium dichromate titration or by spectrophotometric colorimetry.

6. It can complete the digestion of chemical oxygen demand, total phosphorus, and total nitrogen.
