Is there a good analytical testing company to recommend? To test the TEM SEM

The equipment of our unit does not know what you think on your side:

German Zeiss GEMIN 300 SEM.

At present, the highest magnification is 10W (clear observation) with EDS, Japan JEM-2100F high-resolution transmission electron microscope.

The current magnification is 10W (clear observation).

The ranking of third-party testing institutions is: Weipu Technology, Intertek, China Certification and Inspection Group, Pony Testing, Shenzhen Institute of Metrology and Quality Inspection, Bureau Veritas, CTI, TÜV Rheinland, Swiss General Notary Public, and China Guangzhou Analysis and Testing Center.

Intertek Group is the world's leading quality and safety service company, an international authoritative testing agency and a third-party notary firm. Intertek is recognized worldwide for its professionalism, quality and integrity. With a global service network in more than 100 countries, Intertek is a trusted partner to customers around the world by providing the highest standards of impartial, accurate, high-quality service and innovative solutions in the industry.

CTI is a wholly-owned subsidiary of CTI Testing & Certification Group, and an authoritative organization specializing in a series of services such as dimensional measurement, measurement and calibration, technical training, and instrument maintenance. CTI has established a business service network composed of more than 30 branches in China, with dozens of laboratories covering chemistry, biology, physics, machinery, electromagnetism and other fields.

Third-party testing institutions, also known as fair inspection, are commodity inspection activities carried out in accordance with relevant laws, standards or contracts in a fair and authoritative capacity as non-parties.

SGS has a great influence on a global scale, and there are only a few truly local third-party testing companies in China, such as China Inspection and Certification Group Chongqing **** (CCIC), Nanjing Jinli Testing Company (AHK), Intertek (ITS) and so on.

SGS's core services can be grouped into the following four categories:

Inspection: We offer a world-leading full range of testing and verification services, such as inspecting the condition and weight of **merchandise at transit, helping to control quantity and quality and meeting all relevant regulatory requirements in different regions and markets.

Testing: Our global network of testing facilities staffed by knowledgeable and experienced personnel can help you reduce risk, reduce time to market, and test the quality, safety, and performance of your products against relevant health, safety, and regulatory standards.

Certification: Certification enables us to demonstrate to you that your products, processes, systems or services comply with national and international standards and norms or customer-defined standards.

Accreditation We ensure that our products and services comply with global standards and local regulations. By combining global coverage with local knowledge, unrivalled experience and expertise in almost every industry, SGS covers the entire ** chain, from raw materials to final consumption.

I am familiar with the information consultation of the upper study.

I think there are two well-known concepts, one is to show that this organization is confirmed to be very strong and capable, and has made corresponding achievements. 2 is the result of marketing through advertising. On the official website of the Bureau of Quality and Technical Supervision, look for a CMA-qualified testing agency, which has a long existence, and obviously has a certain strength.

Aomai Food Laboratory is located in Heze High-tech Zone, the hometown of Chinese peonies.

GRGT Radio and Television Measurement and Testing Co., Ltd. **** is a relatively good company in the auto parts industry in China.

At present, it mainly relies on enterprises to establish their own capabilities or seek the help of third-party institutions, and auto parts testing includes tests such as temperature and humidity, vibration, ELV, etc. At present, there are also tests for AEC Q, including tests for components and tests for chips mosl@.

However, the R&D cost is relatively high, since it is said that it is a product with a vehicle specification standard product, ask whether your product has obtained the basic certification of CQC, whether it has passed the 16949 standard, and whether there is a project of cooperation with the car factory.

The mountain is not copied in the high, and there is a fairy name; The water is not deep, there are dragons.

Bai Zeling du. Frankly speaking, as long as there is a DAO institution with testing qualifications and meets the requirements of ZHI testing, the report issued by the test is valid. In this regard, start-ups and some small and medium-sized companies naturally cannot compete with some capital bosses, but their testing capabilities and test reports are the same.

Therefore, many times, some companies will be deceived by some marketing and publicity, lose their own judgment, and spend a lot of money to get reports that they don't have to spend a lot of money to obtain. "Cheap is not good, good is not cheap" does not work in the testing world. This sentence cannot be allowed to become the words of some so-called industry tycoons.

In addition, Jiangsu Kebiao medical testing is the first, and the third-party testing of medical devices is carried out. It's easy to use and not expensive, so let's find out.

Institutions that have CMA testing qualifications and meet the testing requirements will be valid. I know of the Shanghai Indoor Environmental Quality Testing Center.

As long as the unknown testing company obtains the qualification through the qualification review, it can issue a test report with the same effect as the well-known testing company (of course, if the customer specifies which testing company's report is needed, it is another matter), but the recognition of the well-known testing company will be higher, especially in the international world.

Yunnan Yuhao environmental monitoring****.

Aomai Food Laboratory is located in Heze High-tech Zone, the hometown of peony in China, and was approved by the State Administration for Market Regulation in 2018. The food laboratory has a construction area of more than 9,000 square meters, designed and built by China's top laboratory design company, with scientific and reasonable structural layout and complete facilities, the laboratory has an independent photo-oxygen inverter ventilation system, biological air conditioning purification system, constant temperature and humidity system, first-class air conditioning system, fire protection system, PLC control sewage treatment system, and has a professional refrigerated and refrigerated sample library and samplesLibraryIntelligent management system.

For the first time, the company has passed the testing of more than 2,000 products and more than 40,000 product parameters, and the company has the certification of CMA qualification and CATL qualification.

Mainly performance, functionality, security, documentation. The main thing is that the requirements of the bidding documents must be tested, and those who do not require it can be simply tested or not tested. If you develop your own software for tuning and testing, you must do functional testing and performance testing.

The test done by CCIC Saichen Hebei Branch is very good, the project acceptance, and the software performance are OK.

The Chinese Academy of Sciences Chinese Academy of Sciences testing is not bad.

1. State-owned enterprise testing institutions: radio and television measurement, national inspection group, guangjian group, Zhongke testing ......2. Foreign-funded testing institutions: SGS, TUV, Intertek, ......Compared with domestic testing institutions, foreign-funded companies like SGS are also more expensive in terms of testing costs, and the service attitude is not very good.

Like the domestic Zhongke Testing, the first is decent, but the later service feels very good, backed by the Chinese Academy of Sciences, the testing team and the quality of the test report naturally do not have to worry. Therefore, it is recommended that enterprises generally find domestic testing institutions.

The above is purely a personal opinion and is ranked in no particular order).

Now there is not even a "well-known testing agency" evaluation criteria, how to determine a well-known testing agency? What's more, the current well-known testing institutions cannot be "well-known institutions" with large network investment and being seen and known by more people, or "well-known institutions" with high publicity and high cost of money

The top ten testing institutions selected by the 12th China Scientific Instrument Development Annual Conference in 2018 (ACCSI2018) are as follows:

1. Guangzhou Radio and Television Metrology and Testing Co., Ltd. ****.

2. Comprehensive Testing Center of Chinese Academy of Inspection and Quarantine.

3. Nanjing Product Quality Supervision and Inspection Institute.

4. Guangdong Provincial Institute of Testing and Analysis (Guangzhou Analysis and Testing Center, China) 5. China Testing and Certification Group Co., Ltd.

7. Guangzhou Jinyu Medical Laboratory Group Co., Ltd.

8. Zhongding testing technology.

9. Shenzhen Information Testing Standard Technical Service Co., Ltd. ****.

10. Suzhou Falab Micro Technology Testing Technology.

There are many third-party testing institutions, with different testing items and areas of focus, and the services and testing certifications provided are also different. If you want to find a third-party testing agency, it is recommended to find a local one, basically every city has this kind of testing agency. For example, in Qingdao, the more well-known third-party testing institutions are Byron testing, and Qingdao Byron testing technical service **** is a relatively well-known third-party testing agency in China.

I know of a third-party testing agency. It can provide one-stop testing and certification services, and has won the title of "national high-tech enterprise".

The company adheres to the value concept of "Lixin, Good Measurement", and is committed to helping customers improve the level of R&D and innovation, improve product quality, and create a better life through excellent service.

A good testing agency generally has several advantages:

1. The instrument is fully equipped, which can solve the testing needs of customers from many aspects.

2. Engineers have many years of industry experience and can judge the experimental data to determine the quality of the product.

It is recommended that you understand the situation when you choose.

CTI Ah, CTI didn't say that the country's largest third-party testing, the service is very good.

China Inspection & Certification Group has branches in various provinces and cities.

Don't go to the Shanghai European testing agency to get a pit, a certificate renewal promised to be a month, and now it has not come out for three months, and I can't find the leader above.

There are quite a lot of testing institutions in Shenzhen, such as Foxconn South China Testing, etc., and Shenzhen's state-owned testing institutions do environmental reliability tests and electromagnetic compatibility tests, electrical safety tests, which are reasonable and provide good service.

Daily chemical product testing, product export, go to SGS, BV Lide, ITS can not be exported, you can go to CTI, AOV, PONY and other testing institutions.
