Mixture composition analysis
Thread Content
There is an emulsion mixture (containing a large amount of water) with about 10 substances in it. How to analyze the composition and content of these substances.
There may be surfactants, foaming agents, inhibitors, etc., but it is not clear what they are.
Ready to dissect someone else’s recipe? This problem cannot be solved by relying on the analysis laboratory alone. It is best to first find someone familiar with this matter to make a rough estimate of the ingredients based on the nature and use of the item, and then use analytical methods to verify it. To analyze some basic properties of a substance that has not been estimated, it is generally necessary to first determine the main functional groups and the content of each component through infrared, gas-liquid phase, and mass spectrometry. In this case, the experience of the synthesizer or formulator is generally very important, and the analysis is more of a auxiliary work.
Thanks for the answer upstairs. This is a task assigned by the company. It’s difficult. I heard that a detailed analysis would cost 20,000 yuan. This post was last edited by lucky1909 on 2009-3-26 17:29 ]
This is a matter of scientific research. Generally, analysis laboratories do not have this capability unless you know the process flow.
Member singlseun is a master in analyzing surfactants. You can look for him. His topic posts http://bbs.hcbbs.com/thread-417099-1-1.html
I also encountered the same thing as the poster. Sometimes, I analyze other people's products, especially surfactants or other trace ingredients. Basically, they cannot be analyzed, such as products with a water content of more than 80%.
First, look at what elements there are in general, do some atomic absorption or something, and then separate them bit by bit and identify them!
