Abstract The current analytical techniques for characterizing printing and graphic arts substrates, particularly those used to date and authenticate provenance, are destructive. This limits the amount of data that can be captured from an individual sample. For samples being evaluated in forensic and archeological investigations, any loss or degradation of the materials is undesirable. Furthermore, it is difficult to produce statistically relevant data for such analytes. We have shown elsewhere that a contactless microwave resonant cavity dielectric spectroscopy technique can discriminate between paper samples made from different plant fiber species based on their lignin content. In this publication, we demonstrate the utility of the contactless resonant cavity dielectric spectroscopy (RCDS) technique in the characterization of naturally and artificially aged paper samples. Based on our experimental results, we suggest that the technique could be used in forensic and archeological investigations of unique paper products.

纤维素纸老化的非接触谐振腔介电谱研究


摘要 当前用于表征印刷和图形艺术基材的分析技术，特别是那些用于确定日期和鉴定出处的分析技术，具有破坏性。这限制了可以从单个样本中捕获的数据量。对于在法医和考古调查中评估的样品，材料的任何损失或降解都是不希望的。此外，很难产生此类分析物的统计相关数据。我们在其他地方表明，非接触式微波谐振腔介电谱技术可以根据木质素含量区分由不同植物纤维种类制成的纸样。在本出版物中，我们展示了非接触式谐振腔介电谱 (RCDS) 技术在自然和人工老化纸张样品表征中的实用性。根据我们的实验结果，我们建议该技术可用于独特纸制品的法医和考古调查。
