I have had a request to analyze 15N of carbonized corn ... if possible. By
carbonized I mean that the corn has been burnt at low temperatures ...
probably in a natural grass fire. It looks like it was burnt fairly
thoroughly though as it resembles charcoal.
I have not analyzed for [N] but my suspicion is that any nitrogen in the
original sample would have been either driven off as N2 or was altered
Has anyone else got any experience with this ?
