连华科技bod测定步骤？ 连华科技cod测定仪操作流程？英文双语对照

一、连华科技bod测定步骤？

答案：华科技bod测定步骤如下：

1. 收集水样：收集被测水样，确保其代表性。

2. 加入营养物质：向水样中加入一定量的营养物质，以刺激微生物的生长。

3. 瓶口注气：将瓶子的空气泵入水样中，以提供微生物所需的氧气。

4. 封闭瓶口：将瓶子的瓶塞密封，避免空气进入。

5. 存放瓶子：将密封好的瓶子放入恒温箱中，存放时间可以根据各种情况而定，通常为5-10天。

6. 氧化还原电位检测：检测瓶子中水的溶液的氧化还原电位。

7. 计算bod值：根据氧化还原电位的变化，计算出bod值。

bod值是有机物在水中被微生物分解消耗氧气的能力的指标，通常用来评价水质的有机污染程度。华科技bod测定的基本原理就是在一定时间内监测水样的溶液中氧化还原电位的变化，该变化值越大，则有机物的浓度越高，bod值也就越大。

同时，bod测定也是一种可靠而灵敏的监测水质的方法，其具有精度高、操作简单等优点。当然，为了获得更加精确的bod值，还需要注意实验中的各种细节，如水样的收集、营养物质的选择和添加量、厌氧条件的控制等等。

二、连华科技cod测定仪操作流程？

1、准备数只反应管置于冷却架的空冷槽上；

2、依次准确量取2.5ml蒸馏水到“0”号反应管中，量取各检测水样2.5ml分别到其他反应管中；

3、依次向各个反应管中加入耗材D试剂0.7ml(建议使用厂家的定量器) 4、依次向个反应管中加入耗材E试剂4.8ml(建议使用厂家的定量器)

5、将各样品充分混匀，放入提前预热到165℃的5B-1型COD消解器中。盖上防喷罩，按“消解”键。同时打开COD测定仪开关进行预热；

6、消解完成后，将各样品依次放到冷却架的空冷槽上，然后按COD消解器的“冷却”键进行空气冷却；

7、空气冷却完成后，依次向各反应管中加入2.5ml蒸馏水并混匀；

8、将混匀后的个反应管放到冷却架的水冷槽(提前加入自来水)中。按“冷却”键进行水冷却；

9、水冷却完成后，将反应管从水冷槽中拿出，擦干外壁水珠。并将溶液依次倒入对应编号的比色皿中(充分混匀)；

10、将“0”号比色皿(空白溶液)放入仪器的比色槽中并关闭上盖；

11、观察3-4秒待数值稳定后，按COD测定仪键盘上的“空白”键，仪器屏幕将显示0000，然后将“0”号比色皿(空白溶液)从比色槽中拿出；

12、将“1”号比色皿放入比色槽中，并关闭上盖。

13、观察3-4秒数值稳定后，此时屏幕上所显示的结果即为1号样品的COD浓度；

14、然后将“1”号比色皿从仪器中拿走，再将“2”号比色皿放入比色槽中，并关闭上盖。观察3-4秒待数值稳定后，此时屏幕上所显示的结果即为2号样品的COD浓度。其他样品测定仪过程类同；

15、比色完成后的溶液，不能随意倾倒，应统一收集，并进行集中处理。

三、连华科技cod测定仪需要校正吗？

如果你感觉到你测的水样值不准确了，可以先做一个标准样品，在仪器上来测一下看看是否准确，如果标样不准确了，你在校正，仪器说明书上有怎样校正的说明，挺简单的。

一般情况下，刚拿到手的仪器是不需要校正的，除非不准，要不就不要进行校正，老校正对仪器不好

One, does Bod of Lian Huake ability determine measure?

The answer: Bod of Hua Ke ability determines move is as follows:

1.Collect sample: Collect the sample that be measured, ensure its are representative.

2.Add nutrient substance: The nurture that adds certain amount to the middle of sample is qualitative, in order to stimulate microbial growth.

3.Opening pours vital energy: Enter the empty pump of bottle sample in, in order to supply the oxygen that microbial place needs.

4.Close opening: The bottle stopper bottle is sealed, avoid air to enter.

5.Deposit bottle: Will sealed good bottle is put into constant temperature box, deposit time to be able to be decided according to all sorts of circumstances, it is 5-10 day normally.

6.Oxidation is reductive potential detects: Detect the oxidation of the solution of the water in bottle is reductive potential.

7.Computational Bod is worth: The basis oxidizes the change of reductive potential, computation gives Bod to be worth.

Bod value is organic matter is in water by microbial the index that decomposes the ability that consumes oxygen, use the organic pollution rate that evaluates water quality normally. The fundamental that Bod of Hua Ke ability determines monitors the change that reductive potential oxidizes in the solution of sample inside proper time namely, this change value is greater, the concentration of organic matter is higher, bod value is greater also.

In the meantime, bod determines also is the method of a kind of reliable and acute water quality that monitor, its have precision tall, operation is simple wait for an advantage. Of course, to obtain more exact Bod value, still need to notice all sorts of detail in the experiment, the choice of material of the collection that is like sample, nutrition and the control that add requirement of oxygen of quantity, be disgusted with are waited a moment.

2, does Cod of Lian Huake ability determine does appearance operate circuit?

1, on the empty cold chamfer that preparative number reacts tubal park refrigeration is worn only;

2, ordinal and exact amount takes 2.5ml distilled water to arrive " 0 " in number response canal, the quantity takes each to detect sample 2.5ml arrives respectively in other response canal;

3, ordinal the ration that joins 0.7ml(of reagent of D of bad news material to suggest to use manufacturer to the middle of each reaction canals implement) 4, ordinal to the ration that reacts 4.8ml(of reagent of E of bad news material is joined to suggest to use manufacturer in the canal implement)

5, mix even each sample adequately, put ahead of schedule warm-up arrives clear up of the 5B-1 of 165 ℃ COD implement in. The oil saver on the lid, press " clear up " key. Open COD to determine at the same time appearance switch undertakes warm-up;

6, after clear up is finished, each sample ordinal the air that puts refrigeration wearing is cold on groove, press COD clear up next implement " cooling " key undertakes air cools;

7, after air refrigeration is finished, ordinal add 2.5ml distilled water to the middle of each reaction canal and mix even;

8, the water-cooling chamfer that puts a reaction valve after mixing even refrigeration wearing (add tap water ahead of schedule) in. By " cooling " key undertakes water cools;

9, after water-cooling is finished however, reaction the canal is taken out from inside water-cooling chamfer, drip of the wall outside wiping. And solution ordinal in the colorimetric Min that joins corresponding number (mix even) adequately;

10, will " 0 " date colorimetric Min (blank solution) upper cover is shut in the colorimetric chamfer that puts an instrument;

11, after observing 3-4 second needs numeric stability, determine by COD on appearance clavier " blank " key, instrument screen will show 0000, next will " 0 " date colorimetric Min (blank solution) take out from inside colorimetric chamfer;

12, will " 1 " date colorimetric Min is put into colorimetric chamfer, shut upper cover.

13, after observing 3-4 second numerical value is stable, the result that shows on screen right now is the COD chroma of a sample namely;

14, next will " 1 " date colorimetric Min is taken away from inside the instrument, again will " 2 " date colorimetric Min is put into colorimetric chamfer, shut upper cover. After observing 3-4 second needs numeric stability, the result that shows on screen right now is the COD chroma of 2 sample namely. Other sample determines appearance process kind with;

15, the solution after colorimetric is finished, cannot optional dump, should unite collect, hand-in-hand travel centers processing.

3, does Cod of Lian Huake ability determine is appearance need corrective?

If you feel the water sample that you survey is not accurate, can make sample of a standard first, will be measured on the instrument look accurate, if standard specimen is not accurate, you are in corrective, there is how corrective specification on instrument manual, quite simple.

Usually, just took in one's hand the instrument is not to need corrective, unless forbid, otherwise does not undertake corrective, old corrective bad to the instrument

10, analysis of deepness of Zhen Huake ability?

Group of Information Industry of electron of company subject China, it is electron of our country special type yuan of domain of parts of an apparatus integrated model bibcock. In recent years the company comes off ceaselessly small qualitative capital fund, focusing yuan parts of an apparatus advocate course of study, the product covers the base such as component of parts of an apparatus of the feeling that hold block, schism, integrated circuit, Electromechanical extensively yuan parts of an apparatus, at present battalion of business of company special type closes occupy than exceeding 80% .

Yuan parts of an apparatus ranks industrial catenary upper reaches, be benefited equipment to the limit of one's capacity + dosage promotes + homebred replace ternary drive

Special type electron yuan parts of an apparatus is located in upper reaches of catenary of war industry industry, most react first trade demand, downstream application is wide at the same time, not be enslaved to be enslaved to is onefold domain or model, the integral scene bearing of war industry industry can be represented on certain level. Determinism of war industry of 945 national defence is tall grow, special type electron yuan parts of an apparatus is benefited not only the weaponry to the limit of one's capacity that military modernization brings, at the same time also informatization of benefit from benefit from issues the electron in new-style equipment yuan the promotion of dosage of parts of an apparatus. From board piece in light of fractionize, active space of yuan of market of parts of an apparatus and add fast general prep above is passive yuan of parts of an apparatus, at the same time inferior homebred change rate also bring more capacious replace a space, because this is active,business occupies yuan of parts of an apparatus than higher company, tall growing attribute also more highlight.
