High-resolution palaeodietary reconstruction: Amino acid δ13C analysis of keratin from single hairs of mummified human individuals

Stable isotope analysis of mummified human hair allows the reconstruction of the recent life histories of individuals that died thousands of years ago. The objective of this study is to improve the resolution of hair palaeodietary reconstruction by sequentially analyzing 0.5 cm segments of a single hair using liquid chromatography-isotope ratio mass spectrometry (LC/IRMS).
