Can nuclear magnetic resonance be used to determine the protein content, fat content, and moisture content of a sample? This post was last edited by Canghai Yili Sha on 2009-3-19 14:39.]
1. Nuclear magnetic resonance is generally used to study the structure of substances; it is unlikely that it can be employed for quantifying the several components you mentioned. However, I have no experience with this type of instrument, and based on my memories from school, my answer would likely be no. 2. I suggest you first read some books on instruments related to this field. I hope you can provide us with an answer. Hehe, it seems like I’m assigning you a task here
The NMR sample must be a pure single component; multi-component samples or those containing impurities will result in NMR spectra that are too complex to analyze!
Nuclear magnetic resonance can be used to determine the chemical molecular structure of organic substances. From its spectrum, one can obtain: chemical shift values (absorption peaks), spin system classification and coupling constants, as well as the heights of the integration curves.
Hehe, using a near-infrared analyzer is very simple, practical, and fast for determining protein content including amino acids, as well as fat and crude fiber levels
NMR in chemistry: It utilizes the chemical environment of hydrogen atoms or carbon-13, as well as the differences in such environments, to determine the structure of substances. The protein content and fat content mentioned by LZ can be determined using instruments such as infrared and ultraviolet spectroscopy, while the water content can be calculated through loss on drying.
The problem is solved. Although everyone’s answers didn’t quite satisfy me, I’m still very grateful.
Although I understand it now, I still support it. Take a look at http://bbs.hcbbs.com/thread-363816-1-1.html. Or it is recommended to consult materials such as \"Instrumental Analysis\" and so on.
There are mainly proton and carbon-13 nuclear magnetic resonance spectrometers, which are used to determine the positions of hydrogen and carbon in organic compounds; they are very expensive! (Personal opinion)
