Hello, what unit should I go to do liquid composition analysis and chemical composition analysis, an

Component analysis is based on the materials provided by the entrusting unit, and the qualitative, quantitative and other analytical methods can be used to analyze the various compositions, element content and filler content of the material. Component analysis refers to the technical method of analyzing the composition of a product or sample through microscopic spectrum and laser detection of molecular structure, and qualitative and quantitative analysis of each component. Compositional analysis techniques can be used to quickly determine what the various components of a target sample are.

Users who need to detect, analyze, and test are recommended to understand microspectrum, and big brands are more assured. [Click on me to communicate with professional technology].

With the development of analytical chemistry, the technology for the analysis of unknown substances has been very complete. But there is still room for improvement in accuracy and precision. You have to analyze the unknown, and according to your requirements, the analytical laboratory technician can judge what kind of ways and methods to take.

More than 90% of the oil leakage problem is because the rubber seal ring has been alternating between cold and warm temperature for a long time, resulting in the loss of a large number of plasticizers and softeners in the sealing ring, and the problem of corrosion, aging and hardening, at first it was oil seepage, and slowly began to drip oil, and the seal ring broke after a long time.

The mechanical seal doesn't say anything.

There are a few companies that have a business in compositional analysis.

Many university analysis and testing centers have external operations.

You can go and consult.

The cost depends on the specific situation of the analysis, not necessarily.

Whether it is expensive or not depends on how you look at it, many testing institutions actually give formula analysis services** or fair, but often**formula** may be cheaper. The formulations are less reliable and may have intellectual property disputes. The product formula I am producing now is made from Inger technology, and the product formula is restored through the existing products

1. What is Component Analysis?

Component analysis is defined as the analysis of samples through modern analysis and separation methods, and the qualitative and quantitative results of the components in the corresponding products are obtained after comprehensive verification of the analyzed spectrum, which is called component analysis.

2. What methods are needed for component analysis?

Thin layer chromatography: a means of separation.

CO2 supercritical: a means of separation.

Rotary evaporation and extraction: means of separation.

Near-infrared spectroscopy: an analytical tool.

Liquid chromatography: separation + analysis means.

Gas chromatography-spectrometry: a means of analysis.

XRD: means of analysis.

ICP-MS: Analytical Means.

Nuclear Magnetic Enhancement (NMR): An analytical tool.

GPC: Analytical Tools.

Femtosecond detection: an analytical tool.

Gas chromatography.

It depends on what you do to analyze the composition of the product, the components of different products are not the same, the more complex the components, the higher the cost, if you want to determine the approximate amount of money, you can describe in detail the samples that need to be analyzed, and the chemical testing institutions here can provide reference.

I've made cosmetics in Shanghai and it's almost 10,000.

I think Wuhan University should be able to do it.

Or in Wuhan chemical research institutes, institutes, colleges, polymer (plastic, rubber, etc.) research institutes, inorganic chemistry research institutes, etc.

It is mainly related to the fact that the sample is liquid, and the sealing problem of the sample crucible is not easy to seal, and there is a problem of overflow during the heating process, so they are worried about contaminating the instrument. I thought that if the crucible had been larger, the liquid sample had been smaller, and not sealed, it might have been easier to work without spilling and contaminating the instrument. You can run and ask in person, and you will be received when you go to the School of Chemistry and the Department of Chemistry of Wuhan University.

You can provide information about the boiling point and melting point of your sample to them; It would be nice if you could tell them the composition of your sample and estimate what physical and chemical changes are at what temperature. Anyway, they charge a fee for the open test to the society; If you have a good relationship, you will be better able to do future tests.

If there is a school nearby, I suggest you go to the School of Chemical Engineering and contact it. You can also go to a specialized testing institution such as SGS to send it for testing.

School of Chemistry, Henan University.

The composition of this slurry formulation is often analyzed.

Through instrument testing, the specific formula ratio is analyzed and restored.

If you want to carry out production, the most advanced way to obtain the formula is to obtain the proportion of each ingredient through sample reduction formula, plus the necessary raw material recommendation and technical support, which can better cooperate with the later production and improve competitiveness. You can stay ** for communication.

Is it a slurry formula for grinding carbon steel and cast iron?
