TOC儀器的測定原理

總有機(jī)碳(TOC)，由專門的儀器——總有機(jī)碳分析儀(以下簡稱TOC分析儀)來測定。TOC分析儀，是將水溶液中的總有機(jī)碳氧化為二氧化碳，并且測定其含量。利用二氧化碳與總有機(jī)碳之間碳含量的對應(yīng)關(guān)系，從而對水溶液中總有機(jī)碳進(jìn)行定量測定。

儀器按工作原理不同，可分為燃燒氧化—非分散紅外吸收法、電導(dǎo)法、氣相色譜法等。其中燃燒氧化—非分散紅外吸收法只需一次性轉(zhuǎn)化，流程簡單、重現(xiàn)性好、靈敏度高，因此這種TOC分析儀廣為國內(nèi)外所采用。

TOC分析儀主要由以下幾個部分構(gòu)成：進(jìn)樣口、無機(jī)碳反應(yīng)器、有機(jī)碳氧化反應(yīng)(或是總碳氧化反應(yīng)器)、氣液分離器、非分光紅外CO2分析器、數(shù)據(jù)處理部分。

Environmental requirements

The instrument shall be operated in a constant temperature and humidity environment suitable for operation. Avoid direct sunlight and abnormal temperature; Too high temperature (over 104 ? F, 40 ℃) will lead to abnormal operation, and too low temperature (below 50 ? F, 10 ℃) will lead to excessive error of measured value.

Use and operation methods

Start the test and count the test times. After the test, the last test result will be displayed. The results of several tests will be automatically saved in the query record. The setting method of detection times is: move the cursor with the "Select" key, modify the number with the "Set" key, press the "OK" key to confirm, and enter the analysis interface. First, carry out four flushing processes

Carbon dioxide sensor

There are two carbon dioxide sensors installed on the instrument, which are composed of conductivity sensor and temperature sensor. Conductivity measurement adopts double precision technology, which can realize automatic calibration and temperature compensation. The TIC sensor is used to detect the concentration of carbon dioxide in the water sample without oxidation, as well as the conductivity value of the water sample; TC sensor is used to detect the sum of the carbon dioxide contained in the water sample itself and the carbon dioxide concentration generated after the decomposition of organic matters in the water sample.

Measuring principle of TOC instrument

The total organic carbon (TOC) is determined by a special instrument - total organic carbon analyzer (hereinafter referred to as TOC analyzer). TOC analyzer is used to oxidize the total organic carbon in the aqueous solution into carbon dioxide and determine its content. According to the corresponding relationship between carbon dioxide and total organic carbon, the total organic carbon in aqueous solution can be quantitatively determined.

According to different working principles, the instrument can be divided into combustion oxidation non dispersive infrared absorption method, conductivity method, gas chromatography, etc. The combustion oxidation nondispersive infrared absorption method only needs one-time conversion, with simple process, good reproducibility and high sensitivity, so this TOC analyzer is widely used at home and abroad.

TOC analyzer is mainly composed of the following parts: sample inlet, inorganic carbon reactor, organic carbon oxidation reaction (or total carbon oxidation reactor), gas-liquid separator, non dispersive infrared CO2 analyzer, and data processing part.

Ultraviolet oxidation

When the UV lamp is used to irradiate the water sample to be tested, the water will be decomposed into hydroxyl and hydrogen groups. The combination of hydroxyl and oxide will generate CO2 and water, and then the newly generated CO2 can be detected to calculate the total organic carbon content. When using the ultraviolet oxidation method, the oxidation capacity can be improved by adding titanium dioxide, persulfate, etc. The advantages of UV oxidation method are high oxidation efficiency and simple maintenance, while the disadvantages are that UV lamps need to be replaced regularly.
