In AOAC 2009.01 and AOAC 2011.25, liquid chromatography-refractive index is used for measuring low molecular soluble dietary fiber.
Can I use ion chromatography to measure low molecular soluble dietary fiber?
Hello Thu Le,
Yes, it seems to be totally possible. But, it seems that some methods that you can apply gives you the monomers of the fibers, and in some cases you have to do a long preparation of the sample. I have a document that compares all the types of methods on mesuring fibers and reports the problems or situation you can find. There's just one problem: it's writting in portuguese, because it was published by an important Research Institution on Brazil. If you want I can send to you and help you to translate.

Hello Thu Le,
Here you have. But, it was not possible attach, so I put the link here. I also found a portuguese thesis about what you want to study (second one)
I hope I've helped you. If you have some doubt about the language you can ask me again.
Thanks and good luck!
