UV灯的使用寿命为6个月，当更换时间到期时仪器将出现警告信息，提醒用户更换UV灯。

二氧化碳测量循环

仪器每4分钟检测得出一个数据（包括TOC值和电导率值），在4分钟的测量循环中TC和TIC是独立检测的。

装箱清单

测定原理：仪器采用紫外氧化的原理，将水溶液中的总有机碳氧化为二氧化碳，并且测定其含量，二氧化碳的测试采用的是直接电导率法，通过测试经过氧化反应的水溶液总碳含量和未经过氧化反应的样品总无机碳的含量差值来测定总有机碳含量，即：总有机碳（TOC）=总碳（TC）-总无机碳（TIC）。

TOC就是关于进行改进和如何最好的实施这些改进的一套管理理念和管理原则，可以帮助企业识别出在实现目标的过程中存在着哪些制约因素——TOC称之为“约束”，并进一步指出如何实施必要的改进来一一消除这些约束，从而更有效的实现企业目标。

The service life of UV lamps is 6 months. When the replacement time expires, the instrument will display a warning message to remind the user to replace the UV lamp.

Carbon dioxide measurement cycle

The instrument detects data (including TOC and conductivity values) every 4 minutes, and TC and TIC are independently detected during the 4-minute measurement cycle.

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.

从理论上对化工污水TOC与COD_a的相关性进行了分析,对在实际工作中测得的TOC和COD_a数据进行了回归分析。结果表明,化工污水的TOC和COD_a之间有着良好的相关性。在一定条件下,利用回归方程可以从测得的TOC值推算出COD_a值,或者从COD_a值推算出TOC值。因此,TOC值可以用来表示有机废水的污染程度,也可做为有机污染物的一个控制指标。

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.
