May I ask, what methods do formaldehyde testing institutions use to detect formaldehyde?

Formal and professional formaldehyde testing institutions use phenol reagent spectrophotometry, which is currently the most accurate method for detecting formaldehyde, this method is one of the most reliable detection methods at present, Shupai environmental protection is a widely praised authoritative testing unit in Hangzhou, the use of such a detection method, for the people of Hangzhou for many years, the strength is reliable, good reputation.

It can be judged according to the following points whether the company is as professional as Hangzhou Environmental Health Testing.

1) A formal governance company requires qualifications and construction certificates.

2) Guarantee the safety and quality of the product. Whether the products launched by the company are produced by themselves, or are they made by a foreign shell company.

3) Professional team, whether it has a professional engineer with a national advanced governance technology certificate, and whether the enterprise has a back-end.

4) Cases. Whether there are large enterprises or ** units have cooperated. Priority is given to cooperative units with kindergartens or schools.

The detection methods include formaldehyde detection box, formaldehyde detector, and now there are many testing units on the market, if you want to save money and rest assured, you can use the test box to test it, and the conventional detection should include formaldehyde, benzene, and TVOC. In addition to formaldehyde is a big deal, it is best not to believe those pineapples, vinegar, etc., it only covers some of the taste, and can not be removed from the root, and the pineapple will rot after a long time, he will also have germs, and at the same time the value of TVOC increases, reducing people's immunity. It is still possible to put some formaldehyde removal materials and photocatalysts, and some photocatalyst wood essential oil can be brushed on the furniture to decompose formaldehyde and prevent formaldehyde from being released into the air, and the effect is very good.

There is also to pay attention to ventilation, ventilate for a period of time in the morning and evening, and close the doors and windows at other times, which is the correct ventilation method. It is best to find a professional governance agency for testing, and Naga can remove formaldehyde.

Consumers should first confirm that the third-party company they are looking for holds CMA qualifications through online or ** consultation. Secondly, it is necessary to understand the scope of the third-party organization's inspection and testing capabilities. If the indoor formaldehyde exceeds the standard, formaldehyde is a toxic gas, long-term exposure will be harmful to human health, before moving in must do a good job of aldehyde removal measures, completely remove formaldehyde, the following is recommended for you several well-received aldehyde removal methods, for your reference, hope you move into a new home as soon as possible.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

3. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

6. The fresh air system can ensure that the home is in a ventilated state 24 hours a day, which can greatly increase the exchange of indoor air and the outside world, although the effect is very good, but the first fresh air system is more expensive, and the installation before decoration is a better choice

Answer each city formaldehyde testing company is different, large companies must be more professional, once found that formaldehyde exceeds the standard, aldehyde removal is an urgent work, the following for you to introduce some small methods of aldehyde removal, I hope you can efficiently control formaldehyde.

1. Using activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

2. Green plants, aloe vera, cactus, pothos and other plants have a certain absorption capacity for formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde.

Formal formaldehyde testing institutions generally have CMA qualifications, and if you want to be authoritative, you can choose official laboratories such as the Quality Supervision Bureau, the Center for Disease Control and Prevention, and the Environmental Protection Bureau.

Be sure to choose a regular formaldehyde testing company, because now some companies in addition to formaldehyde first take formaldehyde detection as the entry point and then let formaldehyde removal, the state stipulates that the formaldehyde removal company and the formaldehyde testing company cannot be the same company.

Choosing a formal formaldehyde testing authority can go to the official website of the Quality and Technical Supervision Administration to find, with CMA qualification testing institutions, this is the most basic condition. Then see if there are any items in its business scope that can do formaldehyde testing. In addition to these, it should also be noted that the existence of the formaldehyde testing agency is the problem.

The longer period of time indicates that the institution has the strength and can better reflect the ability, because the CMA qualification is not long-term, and basically it takes 3 years to pass the review again before the testing business can be carried out. Therefore, the number of years of existence reflects the operating status of this institution.

There are two main types of professional testing institutions: one is a professional research institution or a business unit under the management of the first class; The other type is private testing companies. Professional testing is multiple-point, multi-point testing.

To entrust a professional testing institution of Beijing Dayuan Environmental Testing Technology Research Center, you need to make an appointment in advance, take the air back to the laboratory for testing after sampling the air on site, and wait at least 2-3 working days to get the results, which is relatively high. Theoretically, the test results are the most accurate, and only human factors such as on-site operation errors will affect the accuracy of the test results.

In addition, there is a class of formaldehyde detection instruments on the market - formaldehyde detector (formaldehyde speed tester), as long as you can buy it on a treasure, the first span is larger, but the current detection principle of formaldehyde speed tester is not in the national standard specification, so it is not discussed.

The question is how to choose a formal formaldehyde testing agency.

What is in line with authority must be regular. So what is authoritative?

Look at the qualifications: one is CMA (China Metrology Certification Qualification), and the other is CNAS (China National Accreditation Service for Conformity Assessment). Find those with these two qualifications to be authoritative, that is, formal.

First of all, see if the company has an official website and whether it has CMA certification qualifications.

Formaldehyde generally exists in wood, wood core board adhesives, some paints, leather everything has a large amount of formaldehyde, as for whether formaldehyde exceeds the standard, you can only find a local testing agency to rely on professional instruments to monitor, or buy a formaldehyde test box online to test yourself. If the content does not exceed the national standard, then in addition to ventilation you have to buy some charcoal, quicklime and other adsorption materials to prevent in the furniture, if it exceeds the calibration, then it is necessary to take certain measures to get some nano live ore, with the herb Di% Yalin, the treatment of formaldehyde will be better. Therefore, everyone should pay attention to the purchase of materials when decorating.

Answer: We can go to the local environmental protection bureau or environmental inspection bureau, both of which are ** institutions with professional equipment, but these two departments generally do not test privately, and even if they do, they are very expensive.

You can find a specialized testing company to do the test, to choose the qualification, they will have professional testing personnel to provide door-to-door service, first take the indoor air to do the sample, and then go back to the laboratory to do sample analysis, and there will be a test report to type, the process is very detailed, and there will be a solution.

Ask how to choose a testing company.

Ask what kind of qualifications you have, many formaldehyde removal companies have, free measurement of formaldehyde projects. I'm afraid they'll be fake.

Shanghai Wood Industry Research Institute can be an authoritative testing organization.

Formaldehyde testing agency, Guolian Quality Inspection is an authoritative organization specializing in testing.

Kebiao testing can do formaldehyde testing, professional testing institutions, how to contact you?

Method 1: Ventilate the smell or feeling in the room to detect formaldehyde, if you feel dizzy, fatigue, sore eyes, dry throat and other symptoms recently, it may be formaldehyde affecting life;

Method 2: The growth and change of animals and plants, if there is formaldehyde effect on animals and plants at home, there will also be some symptoms, such as animals and animals are weak and do not like to move, and plants are dry and yellow, which may be excessive formaldehyde.

Method 3: Chain Lingzhao buys formaldehyde self-test box for testing, and before the formaldehyde self-test box detects formaldehyde, it also needs to be tested after the closed space is closed indoors, otherwise the results of the test will be affected. There is a test strip in the test box, and if the formaldehyde exceeds the standard, the color of the test strip will change.

Generally, there will be instructions for use, and it is generally possible to test formaldehyde indoors.

Method 4: If you want to be more accurate, or hire a professional formaldehyde removal company is more reliable, in addition to the formaldehyde company's formaldehyde testing service atmosphere two, one is ordinary monitoring, the other is more authoritative CMA testing, is needed to get a third-party testing agency for testing, if you want a more accurate way, choose CMA testing, or office, company, large-scale engineering inspection and acceptance can use CMA testing, more accurate, authoritative, test results will be very accurate.

After buying a new house or interior decoration, it is necessary to carry out formaldehyde testing, which is very necessary, if there is no formaldehyde detection, formaldehyde exceeds the standard and do not understand, or ask a professional company to remove formaldehyde is better.

There are still many professional testing companies, such as ice rats, which have professional formaldehyde detection capabilities.

After the new house is renovated, there may be a certain amount of formaldehyde left in the room. What is the method of formaldehyde detection? PChouse will take you to find out.

This method of formaldehyde detection box is the most economical and safest detection method to operate, and the specific operation is as follows:

1. Before testing, the test space should be sealed for 1 hour before the absorption box can be opened, and then all the white bottle reagents can be poured into the absorption box.

2. Remember to close the absorption lid after it is done, and gently shake the absorption box to it, so that the dissolved matter can be completely dissolved. Then open the absorption box to prevent it from being in the test space for 30 minutes (80-150 cm from the ground).

After a few minutes, you can completely pour the brown reagent into the absorption box, shake it gently, close the lid and let it stand for 10 minutes.

4. At this time, you can take the color card to compare colors, and generally speaking, you can see how much formaldehyde concentration value per cubic meter of air in the measured space is.
