Under certain environmental conditions, post-depositional diagenetic loss of bone collagen can severely reduce the number of bones from a particular archaeological site that are suitable for stable isotopic analysis or radiocarbon dating.

This study examined nearly 300 bones from 12 archaeological sites across southern England known to yield poor or variable preservation to try to identify one, or more, pre-screening technique(s) that would indicate suitable collagen preservation for radiocarbon dating.

A chemical reaction is the process by which one or more substances are changed into one or more different substances.

Excessively long ultrafiltration time was suspected to have contaminated the bone samples with material from the ultrafilter, because those samples exhibited older C ages of unfiltered gelatin extracted from well-preserved bones can be sufficiently accurate, and that care should be taken not to contaminate bone gelatin during ultrafiltration.

Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
