Hi All,

This may seem like a silly question, but while I was drying down acidified
sediment samples for d13C analysis, some of the samples appeared to be
overbaked. The dried sediment in the centre of the bottom of the vial had
a slightly scorched appearance whereas the sediment on the periphery
appeared to dry ok.

How would the d13C signature of these overcooked samples be affected, if
at all? I know the samples get thrown into a furnace in the end, but I
would like to know if my sample prep procedure could affect any results.

Thanks.
