在線離線一體TOC分析儀   二氧化碳傳感器

儀器上安裝有兩個二氧化碳傳感器，由電導率傳感器和溫度傳感器組成。電導率測量采用雙精度技術，可以實現自動校準和溫度補償。TIC傳感器用于檢測未經氧化的水樣中二氧化碳濃度，同時檢測水樣的電導率值；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分解后產生的二氧化碳濃度的總和。

在線離線一體TOC分析儀   分流器

水樣進入儀器后分成相同流量的兩路，其中一路通過延遲線圈進入二氧化碳傳感器，檢測TIC，另一路通過氧化反應器利用紫外燈（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。

更換蠕動泵管

蠕動泵管在長期運行后會有磨損和老化現象，所以必須定期更換。

更換泵管的操作步驟如下：

○1 關閉主電源開關，拔去電源線。

○2 按下泵頭下部的金屬彈片，彈出兩個塑料卡片。

○3 從甭管的接頭處拆下舊的蠕動甭管，取下套在甭管上的抱箍，將抱箍套在新

的蠕動泵管上，然后將新的甭管裝入儀器的接頭上，要注意抱箍的位置及方向。

○4 將甭管嵌入兩個塑料卡片，然后向下壓入卡位。按下時一定要注意甭管是否

入槽。

○5 調整卡片上的流速調節鍵，要注意調整的原則是：管路出液口的液體順暢自

然，無回流。條件允許的話，請使用高精度的量筒對出液速度進行測量，使液體的流

速與儀器的流速設置值相對應。

更換以上部件時存在問題可聯系儀器廠家解決。

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.

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.

Replace the peristaltic pump tube

The peristaltic pump tube may experience wear and aging after long-term operation, so it must be replaced regularly.

The operation steps for replacing the pump tube are as follows:

Turn off the main power switch and unplug the power cord.

Press the metal spring at the bottom of the pump head and pop out two plastic cards.

○3 Remove the old peristaltic pipe from the joint of the pipe, remove the clamp on the pipe, and place the clamp on the new one

On the peristaltic pump tube, then install the new tube into the joint of the instrument, paying attention to the position and direction of the clamp.

Insert two plastic cards and then press them down into the slots. Be sure to pay attention when pressing, regardless of whether it is pressed or not

Enter the slot.

Adjust the flow rate adjustment key on the card, and pay attention to the principle of adjustment: the liquid at the outlet of the pipeline should be smooth and self regulating

However, there is no reflux. If conditions permit, please use a high-precision measuring cylinder to measure the liquid flow rate and ensure the flow of the liquid

The speed corresponds to the flow rate setting of the instrument.

If there are any problems when replacing the above components, please contact the instrument manufacturer for resolution.

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 uses the direct conductivity method, which determines the total organic carbon content by measuring the difference between the total carbon content of the oxidized aqueous solution and the total inorganic carbon content of the unoxidized sample. That is, total organic carbon (TOC)=total carbon (TC) - total inorganic carbon (TIC).

2. Adopting embedded system and touch screen design, pure Chinese operation is convenient and simple.

3. Design and conduct testing for the total organic carbon content of pharmaceutical water (TOC content below 1000ppb).

4. Equipped with a large amount of storage space, capable of storing a large amount of test data.

5. Print in Chinese, output test parameters and test results.

6. No gas or reagents are required during use, storage, and replacement, and there are no moving parts, reducing repair and maintenance costs.

When the concentration of the test sample exceeds the specified limit, the instrument can automatically alarm and output a control signal.

8. According to the testing plan specified in the 2010 edition of the Chinese Pharmacopoeia, IQ/OQ/PQ services can be provided.

Oxidation reactor

The instrument uses UV rays to oxidize organic compounds into carbon dioxide under the action of titanium dioxide photocatalyst. The oxidation reactor is a spiral shaped quartz tube wrapped around a UV lamp. UV lamps emit light at 185nm and 254nm, causing aquatic products to undergo photodegradation.

H2O hν(185nm) (TiO2) OH? H?

Hydroxyl radicals (OH?) can completely oxidize organic compounds into carbon dioxide.

Organic matter OH?CO2 H2O

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