Measurement principle: The instrument adopts the principle of ultraviolet oxidation to oxidize the total organic carbon in the aqueous solution to carbon dioxide and determine its content. The carbon dioxide test adopts the direct conductivity method, which determines the total organic carbon content by testing the difference between the total carbon content of the oxidized aqueous solution and the total inorganic carbon content of the sample without oxidation reaction, that is, total organic carbon (TOC)=total carbon (TC) - total inorganic carbon (TIC).

TOC is a set of management concepts and principles about making improvements and how to best implement them. It can help companies identify the constraints that exist in the process of achieving their goals, which TOC refers to as "constraints", and further point out how to implement necessary improvements to eliminate these constraints one by one, in order to more effectively achieve their corporate goals.

The nature or quality of wastewater is a comprehensive characteristic exhibited by a complex system composed of water and various impurities, which is important in engineering practice The unit of acute toxicity is usually expressed as the half lethal concentration (LD50) of the toxic substance or wastewater that causes 50% death of the test organism within a specific exposure time.

Theoretical analysis was conducted on the correlation between TOC and COD_a in chemical wastewater, and regression analysis was performed on the TOC and COD_a data measured in practical work. The results indicate a good correlation between TOC and COD_a in chemical wastewater. Under certain conditions, the COD_a value can be calculated from the measured TOC value using regression equations, or the TOC value can be calculated from the COD_a value. Therefore, TOC value can be used to indicate the degree of pollution in organic wastewater and can also be used as a control indicator for organic pollutants.

There is a good correlation [Z, 31]. Preface: In the same wastewater sample, if there is no other interference and the oxidation is complete, the measured TOC value is directly proportional to the COD value. For a long time, the degree of organic matter decay in water bodies has been evaluated as COD-KTOC. Since C Oz-CO is calculated, the classic methods are used to determine COD and BOD. BOD/5-32/12=2.667.

Application scope

This instrument can be used to detect the concentration of organic carbon in purified water, injection water, and deionized water in the pharmaceutical industry; It can also be used for the detection of TOC in ultrapure water in the semiconductor industry.

In the pharmaceutical and biochemical fields, it can be used to verify the cleaning effect during the cleaning validation process.

This instrument has online detection function, which can monitor the water production system in the pharmaceutical industry, the ultrapure water preparation system and chip process in the semiconductor industry, and the deionized water preparation process in power plants online.

Offline detection

When conducting offline testing, the instrument can directly sample from sample bottles or other containers without pressure. Instrument pipeline flushing and instrument calibration should be operated offline. If there are insoluble particles in the sample, they should be filtered through a filter membrane (with a pore size of 60μm or smaller) before entering the instrument to prevent particles from blocking the instrument. The injection tube of the instrument is a 1/16 inch Teflon tube, and the flow rate of the water sample drawn into the pipeline by a peristaltic pump is about 0.5 ml/min.
