北京纯水TOC分析仪介绍  水样中TOC的分析步骤

水中的有机物质的含量，以有机物中的主要元素一碳的量来表示，称为总有机碳。TOC的测定类似于TOD的测定。在950℃的高温下，使水样中的有机物气化燃烧，生成CO2，通过红外线分析仪，测定其生成的CO2之量，即可知总有机碳量。

北京纯水TOC分析仪介绍  水中TOC的监测

我们的生活离不开水，若相当多的有机污染物存在于水中，将直接影响水体的质量，对我们的生活和生产造成危害，因此水和废水的监测，越来越引起人们的重视。其中水体中总有机碳(TOC)含量的检测，日益引起关注。它是以碳含量表示水体中有机物质总量的综合指标。TOC的测定一般采用燃烧法，此法能将水样中有机物全部氧化，可以很直接地用来表示有机物的总量。因而它被作为评价水体中有机物污染程度的一项重要参考指标。

Analysis steps of TOC in water samples

The content of organic matter in water, expressed by the amount of carbon, the main element in organic matter, is called total organic carbon. The determination of TOC is similar to the determination of TOD. At a high temperature of 950℃, the organic matter in the water sample is gasified and burned to generate CO2. The total organic carbon content can be determined by measuring the amount of CO2 generated through an infrared analyzer.

Monitoring of TOC in water

Our lives cannot do without water. If a considerable amount of organic pollutants exist in water, it will directly affect the quality of the water and cause harm to our lives and production. Therefore, the monitoring of water and wastewater is increasingly attracting people's attention. The detection of total organic carbon (TOC) content in water bodies is increasingly attracting attention. It is a comprehensive indicator that represents the total amount of organic matter in water using carbon content. The determination of TOC generally adopts the combustion method, which can oxidize all organic matter in the water sample and can be directly used to represent the total amount of organic matter. Therefore, it is regarded as an important reference indicator for evaluating the degree of organic matter pollution in water bodies.
