Where can I test for chemical analysis?

Total Composition Analysis of Test Chemicals: Composition research analysis is an instrument that can be used to analyze and measure the composition and properties of substances. In the process of industrial development and production management of modern enterprises, it is necessary to carry out systematic automatic detection and automatic control of the chemical composition, chemical properties, viscosity, concentration, density, severity and pH value of raw materials, finished products and semi-finished products in the process of production activities, so as to achieve high yield, reduce energy theft consumption and product quality costs, ensure the production of information security technology and protect the ecological environment.

The problem of component analysis is that we use Chinese element detection, component analysis, comparative result analysis, material identification, unknown component analysis, quantitative analysis and detection ability analysis and other analytical teaching methods to obtain the chemical name and content ratio of the basic raw materials of the sample.

Ingredient analysis seems to be hot these days, and all kinds of skincare products will add a little ingredient analysis.

Flow of Component Analysis:

1. Sampling evaluation: According to the customer's requirements and purposes, it is difficult to evaluate the sample analysis, and inform the customer:

2. Sign the contract: discuss each detail in detail and sign the contract with the customer;

3.Sample pretreatment is mainly to separate the components of the sample through various separation techniques;

4. Instrument testing: infrared, nuclear magnetic resonance, GC-MS, X-fluorescence technology analysis, ICP and other spectrum research and analysis of the main instrument system testing;

5. Analyze the research data: analyze the data of the instrument for testing, and obtain the name and ratio of the chemical course of a sample raw material;

6.Database matching: Match the analyzed data with 1 million databases to ensure the accuracy of the combination;

7. Component verification: According to the information that can be provided by the enterprise customer, verify whether the ingredients from the test results contain the effect ingredients provided by customer management;

8.Publish a test report.

To do the full composition analysis of chemicals, I suggest that you can find Ningbo Qixin Testing, and they have cooperated several times, and the results of the analysis are still very good, I hope it will help you.

For chemicals can not be sloppy, must be accurate, it is recommended that you can go to Shanghai Inger Testing to do the composition analysis of the test, where the reports are relatively accurate, the error is very small, can be trusted.

Some.

China Metrology Certification CMA is only a third-party testing organization that has obtained the metrological certification certificate, and is allowed to use the CMA seal on the inspection report, and the inspection report stamped with the CMA seal can be used for product quality evaluation, results and judicial appraisal, and has legal effect. Metrology certification is not only an effective means for many industries, especially those related to the vital interests of the people, to evaluate the testing ability of testing institutions.

It is a means of compulsory assessment for the inspection institutions (laboratories) that issue notarized data for the society, and it can also be said to be the first compulsory accreditation of laboratories with Chinese characteristics. The data provided by the product quality inspection agency that has passed the measurement certification shall be used for the issuance of certificates, product quality evaluation, and achievement appraisal as notarized data, which has legal effect.

With the transformation and upgrading of China's manufacturing industry, product quality has attracted more and more attention, but in the process of product consumption, it is inevitable that quality disputes will occur, causing contradictions between the parties, and eventually may even go to the judicial route.

And the product quality appraisal center, just to assume the responsibility of product quality disputes in the identification, in the end how to correctly understand the product quality appraisal, in the near future, Guangzhou Zhongke testing technical service **** will hold the unveiling ceremony of the product quality appraisal center, but also because of this, get the opportunity to contact with product quality appraisal experts, through the explanation of the quality appraisal experts of the Chinese Academy of Sciences, to help us more comprehensively, clear understanding of product quality appraisal.

There are a lot of things you said, and generally the institutions that have CMA qualifications are relatively good, and the analysis method of microscopic spectrum is also the most effective. It will help you determine the proportions of each ingredient more effectively.

Zhejiang's have, is at No. 387 Tianmushan Road, the name is "Zhejiang Province Chemical Product Quality Inspection Station", "Zhejiang Provincial Chemical Research Institute Chemical Product Testing Center", **is -85226855 to 3701, you can call ** in detail.

Inger analysis is more recognized by the ingredient analysis, and the accuracy of the test.

Yes, third-party testing institutions can use their testing equipment to do component analysis. If you want to do it yourself, the cost of running a laboratory is very high, whether it is maintenance costs or purchase costs, it is better to spend some money to find a third-party organization to do it. We have previously done compositional analysis at Inger Assays.

Reliable and authoritative component analysis and testing institutions, Zhongke Testing generally uses spectroscopy (ultraviolet, infrared, nuclear magnetic resonance) for component analysis; chromatography (gas chromatography, liquid chromatography, ion chromatography); Mass spectrometry (mass spectrometer, gas synchrometer, liquid mass spectrometry); energy spectrum (fluorescence spectroscopy, diffraction spectroscopy); Thermal spectroscopy (thermogravimetric fractionator, differential scanning calorimetry) comprehensively analyzes the sample, and qualitatively and quantitatively analyzes the components in the sample through the combined application of a variety of separation and analysis methods, so as to determine the structure of the components and have a comprehensive understanding of the sample.

Component analysis can involve the following product types: pharmaceuticals, coatings, adhesives, surfactants, soaps, detergents, printing inks, organic rubber additives, photosensitive materials, catalysts, reagents, polymer flocculants, petroleum additives, food additives, veterinary drugs, feed additives, paper and pulp chemicals, plastic additives, metal surface treatment agents, aroma deodorants, automotive chemicals, bactericidal and antifungal agents, fatty acids, rare earth chemicals, fine ceramics, functional polymers, biochemicals, enzymes, Plasticizers, stabilizers, concrete admixtures, health foods, organic electronic materials, etc.

Don't look for Zhifu (Shanghai) technical service to do testing. A few thousand dollars to buy a piece of paper. The ingredients and proportions are not welt and very unprofessional.

Misleading customers greatly consumes manpower, energy, financial and material resources. After-sales will only delay and perfunctory. Technology messes up to give advice.

In short, it is very unreliable and irresponsible. Tens of thousands of dollars have been wasted.

MSDS is a chemical safety data sheet, not a test report, and there is no need for a third-party organization.

If the manufacturer has its own employees who are proficient in MSDS, it can also write it yourself. There is really no one who is proficient, you can entrust us to handle it. Our high quality and low price, you can no longer find a second in the market with such a high cost performance.

It is even more professional than Shanghai Research Institute of Chemical Industry, Pony, and CTI.

There are many problems with MSDS made by some third-party testing companies fishing in troubled waters, so the testing agency is not necessarily authoritative, and the consulting company has no technology.

MSDS SDS is not the more expensive the better, nor the cheaper the better. , and don't trust the so-called "authority" too. Finding the right and professional and responsible preparer is the most important.

The quality and knowledge of MSDS SDS compilers will directly affect the quality of MSDS SDS.

It's too general. If there is no other basis for judgment, the most basic analytical method can only be used - sampling, determining the chemical composition. If it is an inorganic substance, it can be based on the special physical or chemical properties of the ions, such as the flame color reaction, the solution color of the metal ions, the characteristic reaction of the ions, and so on.

If it is an organic matter, the proportion of each element can be determined after full combustion, and the simplest formula can be inferred, and then the molecular formula can be determined by mass spectrometry, nuclear magnetic resonance hydrogen spectroscopy, infrared spectroscopy, ultraviolet spectroscopy, etc., and finally its type and structural formula can be inferred according to the characteristics of functional groups.
