在线离线一体TOC分析仪   二氧化碳传感器

仪器上安装有两个二氧化碳传感器，由电导率传感器和温度传感器组成。电导率测量采用双精度技术，可以实现自动校准和温度补偿。TIC传感器用于检测未经氧化的水样中二氧化碳浓度，同时检测水样的电导率值；TC传感器用于检测水样本身含有的二氧化碳和水样中有机物经分解后产生的二氧化碳浓度的总和。

在线离线一体TOC分析仪   分流器

水样进入仪器后分成相同流量的两路，其中一路通过延迟线圈进入二氧化碳传感器，检测TIC，另一路通过氧化反应器利用紫外灯（UV灯）加二氧化钛薄膜光催化氧化作用将有机物分解为二氧化碳，进入二氧化碳传感器检测TC。总有机碳可通过这个差值计算得到：TOC = TC–TIC。

更换蠕动泵管

蠕动泵管在长期运行后会有磨损和老化现象，所以必须定期更换。

更换泵管的操作步骤如下：

○1 关闭主电源开关，拔去电源线。

○2 按下泵头下部的金属弹片，弹出两个塑料卡片。

○3 从甭管的接头处拆下旧的蠕动甭管，取下套在甭管上的抱箍，将抱箍套在新

的蠕动泵管上，然后将新的甭管装入仪器的接头上，要注意抱箍的位置及方向。

○4 将甭管嵌入两个塑料卡片，然后向下压入卡位。按下时一定要注意甭管是否

入槽。

○5 调整卡片上的流速调节键，要注意调整的原则是：管路出液口的液体顺畅自

然，无回流。条件允许的话，请使用高精度的量筒对出液速度进行测量，使液体的流

速与仪器的流速设置值相对应。

更换以上部件时存在问题可联系仪器厂家解决。

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.
