我们提出了一种用于分离木质素中酚类化合物进行放射性碳分析的方法。这些酚类是通过聚合物材料的化学氧化产生的,并通过制备毛细管气相色谱法(PCGC)衍生化用于分离和回收。这种技术可以产生数十微克的纯净、稳定的化合物,这些化合物可以转化为石墨,并通过加速器质谱法(AMS)进行分析。模型风味化合物和过时的木材的分析表明,在大多数情况下,个别化合物的放射性碳(14C)含量,校正的衍生物的贡献,同意与散装材料的20%以内。
We present a method for the isolation of phenolic compounds derived from lignin for radiocarbon analysis. These phenols are generated by chemical oxidation of polymeric materials and derivatized for separation and recovery by preparative capillary gas chromatography (PCGC). This technique yields tens of micrograms of pure, stable compounds that can be converted to graphite and analyzed by accelerator mass spectrometry (AMS). Analysis of model flavor compounds and dated woods indicates that, in most cases, the radiocarbon (14C) contents of the individual compounds, corrected for the contribution of the derivative, agree with that of the bulk material to within 20%.
