The routine high-performance liquid chromatographic extraction of five amino acids: Haynes, CV, Radiocarbon: The results showed that isotopic variability, when existing, is related to the interindividual differences rather than the different protocols. All of the bone samples that yielded 14 C dates also gave excellent collagen fingerprints, and conversely those that gave poor fingerprints also failed dating. Download full-text PDF.
