Evaluation of wood pretreatments on oak and cedar.
Abstract
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 a-cellulose for both. This study investigates the thoroughness of a range of pretreatment processes by the stable isotope analysis of the products.
