系統(tǒng)組成

TOC分析儀的組成包括以下7個主要部分：

① 在線檢測裝置（在線型儀器配備）

② 樣品蠕動泵

③ 分流器

④ 氧化反應(yīng)器

⑤ 二氧化碳傳感器

    ⑥ 微處理控制器和電子線路板

⑦ 輸出接口

分流器

水樣進(jìn)入儀器后分成相同流量的兩路，其中一路通過延遲線圈進(jìn)入二氧化碳傳感器，檢測TIC，另一路通過氧化反應(yīng)器利用紫外燈（UV燈）加二氧化鈦薄膜光催化氧化作用將有機物分解為二氧化碳，進(jìn)入二氧化碳傳感器檢測TC。總有機碳可通過這個差值計算得到：TOC = TC–TIC。

二氧化碳傳感器

儀器上安裝有兩個二氧化碳傳感器，由電導(dǎo)率傳感器和溫度傳感器組成。電導(dǎo)率測量采用雙精度技術(shù)，可以實現(xiàn)自動校準(zhǔn)和溫度補償。TIC傳感器用于檢測未經(jīng)氧化的水樣中二氧化碳濃度，同時檢測水樣的電導(dǎo)率值；TC傳感器用于檢測水樣本身含有的二氧化碳和水樣中有機物經(jīng)分解后產(chǎn)生的二氧化碳濃度的總和。

operational principle

This instrument adopts the principle of ultraviolet oxidation to oxidize organic matter in the sample to carbon dioxide. The measurement of carbon dioxide is carried out using the direct conductivity method. The total organic carbon content is determined by measuring the difference between the total carbon content of the sample that has undergone oxidation reaction and the total inorganic carbon content of the sample that has not undergone oxidation reaction. That is, total organic carbon (TOC)=total carbon (TC) - total inorganic carbon (TIC).

(1) High precision, high sensitivity, and simple operation.

(2) Humanized operation interface, with one click operation function and automatic pipeline cleaning function.

system composition

The composition of TOC analyzer includes the following 7 main parts:

①Online detection device (equipped with online instruments)

②Sample peristaltic pump

③Diverter

④Oxidation reactor

⑤Carbon dioxide sensor

⑥Microprocessor controllers and electronic circuit boards

⑦Output interface

Diverter

After entering the instrument, the water sample is divided into two paths with the same flow rate. One path enters the carbon dioxide sensor through a delay coil to detect TIC, while the other path decomposes organic matter into carbon dioxide through the photocatalytic oxidation of titanium dioxide film using a UV lamp in an oxidation reactor, and enters the carbon dioxide sensor to detect TC. The total organic carbon can be calculated by this difference: TOC=TC–TIC.

Carbon dioxide sensor

There are two carbon dioxide sensors installed on the instrument, consisting of conductivity sensors and temperature sensors. The conductivity measurement adopts dual precision technology, which can achieve automatic calibration and temperature compensation. TIC sensors are used to detect the concentration of carbon dioxide in unoxidized water samples, while also detecting the conductivity value of the water samples; The TC sensor is used to detect the total concentration of carbon dioxide contained in the water sample itself and the carbon dioxide produced by the decomposition of organic matter in the water sample.

Usage and operation methods

Start the detection and count the number of detections. After the detection is completed, the last detection result will be displayed, and the results of several detections will be automatically saved in the query record. The way to set the number of detections is to use the "Select" key to move the cursor, use the "Set" key to modify the number, press the "OK" key to confirm, and enter the analysis interface. Perform four flushing processes first

Environmental requirements

The instrument should be operated in a constant temperature, humidity, and suitable working environment. Avoid direct sunlight and abnormal temperatures; Excessive temperature (over 104?F, 40℃) can cause abnormal operation, while low temperature (below 50?F, 10℃) can lead to significant measurement errors.

matters needing attention

The initial packaging material of the instrument needs to be carefully stored, and installation needs to be carried out by our company's professional technical personnel.

If the instrument needs to be repaired for any reason, it must be packed in the original cardboard box to prevent damage during transportation.

Test preparation

1) Place the instrument on a stable and clean operating table;

2) Prepare a container for storing waste liquid and connect the outlet pipeline to the container;

3) Prepare the sample solution for testing. For instruments that have not been tested for a long time, it is necessary to perform pipeline flushing,

The flushing time is generally around 15 to 30 minutes.
