Just a curious question. I wonder if narrowing the range of spectra can be really helpful to improve the confidence in your case?

Hi Roger,

I think your results with the leaves are consistent with what I read from the book sometime before. They say that NearIR waves contains more energy , hence, deeper penetration distance compared to MidIR. The good side is that the reflecting signal contains richer info of the sample, i.e., a few cm below the sample’s surface. The downside is that it may pass through very thin sample, i.e., leaves.

That’s what I think 😉

Thanks for your information, Assaf.

I am also interested in a similar application. Let’s say I want to determine the amount of water and ethanol in gasoline. Based on your feedback, it will be feasible at >1 vol.% right?

Thanks Roger,

I had the same issue. I want to take the picture of how I positioned the SCiO and the sample. I have some scans with fresh garlic unpeeled. Depending on where I scan (bottom or top or side), the spectrum is totally different.
