Bulk sediment can contain carbon from more than one reservoir and occasionally this can lead to a freshwater reservoir effect, such as in hardwater regions or lakes where old carbon is washed in from the catchment during spring melt or floods.Having said that, bulk sediment is widely used for radiocarbon dating, especially in cases when macrofossils are unavailable.Macrofossils include charcoal, wood, plant, bone, shell, and seeds – not rootlets.We recommend isolating macrofossils with tweezers or by sieving in distilled, deionized water. Macrofossils (except shell) will undergo the standard AAA pretreatment.A purchase order is required for for submissions over ,000.A 10% discount will be applied to a single submission of 10 samples or more, or a cumulative project of 10 samples or more where all 10 samples are processed at the same time (same accelerator run, or "wheel").For the analysis of bone samples, collagen is extracted.Always send clean and dry bone samples as damp samples may contain mould which can cause deterioration of the collagen.
