Revealing details of stays abroad by sequential stable isotope analyses along human hair strands
Multi-element stable isotope analyses of δ13C, δ15N, δ34S and δ2H values were performed along scalp hair strands to detect isotopic changes resulting from different stays abroad. One hair strand with a hair lengt...

Humans and Camelids in River Oases of the Ica–Palpa–Nazca Region in Pre-Hispanic Times – Insights from H-C-N-O-S-Sr Isotope Signatures
Thirty years ago the use of isotope abundance ratios (IR) of bioelements in nutrition studies was a rather young discipline (Krueger and Sullivan 1984). Developed from hydrology, geochemistry, cosmo- and geoch...

Inter-and intramolecular isotope correlations in organic compounds as a criterion for authenticity identification and origin assignment
Die globalenδ 13C-Werte organischer Moleküle allein lassen oftmals keinen Schluß darüber zu, ob diese synthetischen oder natürlichen Ursprungs sind, da sich die Bereiche derδ 13C-Werte wegen der existierenden nat...
