Enabling scientific discovery through stable isotope analysis
NIST1547 - Peach Leaves
Below is an informal survey conducted through IsoGeoChem to obtain reasonable estimates of δ15N and δ13C values for the NIST1547 Peach Leaves material. The specific inquiry to IsoGeoChem can be found here. Information about this material beyond this page can be obtained from the NIST domain. A direct link to the formal certificate from the NIST page for this material is here as a pdf. If you would like to add yourself to this anonymous survey, please submit your information to me. The mean and standard deviation for δ15N and δ13C for the survey are emphasized in the first row of the table below. Please note, some submissions are individual samples, some are previously conducted surveys and represent a compilation. The summary values below are in no way accepted by the community but simply represent values obtained during routine analysis.
