二氧化碳測量循環

儀器每4分鐘檢測得出一個數據（包括TOC值和電導率值），在4分鐘的測量循環中TC和TIC是獨立檢測的。

裝箱清單

測定原理：儀器采用紫外氧化的原理，將水溶液中的總有機碳氧化為二氧化碳，并且測定其含量，二氧化碳的測試采用的是直接電導率法，通過測試經過氧化反應的水溶液總碳含量和未經過氧化反應的樣品總無機碳的含量差值來測定總有機碳含量，即：總有機碳（TOC）=總碳（TC）-總無機碳（TIC）。

TOC就是關于進行改進和如何最好的實施這些改進的一套管理理念和管理原則，可以幫助企業識別出在實現目標的過程中存在著哪些制約因素——TOC稱之為“約束”，并進一步指出如何實施必要的改進來一一消除這些約束，從而更有效的實現企業目標。

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.

廢水的性質或水質是水和各種雜質組成的復雜體系所表現出來的綜合特性,這種特性在工程實...急性毒性的單位通常是以在特定暴露時間內使試驗生物死亡50%的毒物或廢水濃度，即半致死濃度LD50來表示。

從理論上對化工污水TOC與COD_a的相關性進行了分析,對在實際工作中測得的TOC和COD_a數據進行了回歸分析。結果表明,化工污水的TOC和COD_a之間有著良好的相關性。在一定條件下,利用回歸方程可以從測得的TOC值推算出COD_a值,或者從COD_a值推算出TOC值。因此,TOC值可以用來表示有機廢水的污染程度,也可做為有機污染物的一個控制指標。

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.
