Evaluation of Wood Pretreatments on Oak and Cedar

In a separate study, we conducted a series of high-precision radiocarbon measurements using wood from Britain and New Zealand to investigate interhemispheric offsets and possible temporal variations. To minimize variability associated with different species, the pretreatment of the oak ( Quercus patraea ) and cedar ( Librocedrus bidwilli ) was to α-cellulose for both. This study investigates the thoroughness of a range of pretreatment processes by the stable isotope analysis of the products.
