[Abstract] This method aims at isolating nonstructural organic carbon (NSC) pools, i.e. soluble sugars and starch, from wood for radiocarbon (14C) analysis at natural abundance levels (≤1 ppt).
Pools are operationally defined to 1) physically isolate pools - prohibiting the use of destructive methods, such as compound-specific enzyme digestion, and 2) minimize possible contamination with extraneous carbon form organic solvents.
[摘要] 该方法旨在从木材中分离天然丰度水平的非结构有机碳（NSC）池（即可溶性糖和淀粉）用于放射性碳（ 14 C）分析 ）。
池的操作定义为：1）物理隔离池 - 禁止使用破坏性方法，如化合物特异性酶消化，以及2）尽量减少可能被外部碳形成的有机溶剂污染。
