Small Samples, Big Insights: Ethical Sampling of Archaeological Teeth for Precise Isotope Analysis
Start a new DMP in Loading
Strontium isotope analysis of dental elements is crucial for studying mobility but has its limitations. Manual sampling allows for highly precise analysis but is destructive as it often requires tooth extraction. Laser ablation sampling is less invasive, yet the associated analytical instrument offers lower precision. This project validates a portable laser ablation system (pLA) that causes minimal damage to tooth enamel while ensuring highly accurate analysis of the ablated material. This innovative method combines ethical benefits with analytical precision, providing a minimally destructive solution for precious archaeological, museum, and forensic specimens
