Methodological Considerations for the Use of Acid‐Based Pre‐Treatment Protocols for Carbon and Oxygen Analysis of Tooth Enamel

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 20, 30 October 2025.
ABSTRACT Rationale Chemical pre‐treatment is a common methodological step aimed to remove exogenous materials introduced to archaeological tooth enamel in the burial environment through diagenetic processes.
