do you know the following papers? Maybe you could try to find the
person who made the blood analyses.
Hobson, KA & Clark, 1993, The Auk, Turnover of 13C in cellular and
plasma fractions of blood: implications for nondestructive sampling
in avian dietary studies.
Hobson, K A, Gibbs, H L, Gloutney, M L, 1997, Canadian Journal of
zoology, Preservation of blood and tissue samples for stable-carbon
and stable-nitrogen isotope analysis.
(also on bird blood samples)
>Dear Isotope analysts,
>I have just received a request to analyze 15N and 13C in blood samples that
>will be taken from birds. Does anyone have experience with this type of
>analysis? The samples will be taken from sparrows that are very small so
>only 30 uL of blood can be removed.
>Using an EA analyzer, could the blood just be absorbed onto Chromosorb W,
>and then wrapped in the tin?
>We may also want to analyze 34S in the blood, but we are not set up to do
>this analysis at the moment. Are there other labs that analyze outside
>samples for 34S? If so, what is the minimum quantity of S required for
>Does anyone know typical concentrations of N,C and S in blood?
