I have a wooden cubic sample which is 1cm*1cm*1cm.
Inside of wood, there are sulfur compounds such as FeS, FeS2, etc.
I'd like to find species of Sulphur compounds and want to do some
Quantitative analysis.
I read some paper that XANES analysis is appropriate for the quantitative analysis of Sulphur species. but I can't use XANES right now. is there any other analytical method for the quantitative analysis of sulfur? thank you.
