摘要
利用气相色谱法和高效液相色谱法对7种印油印章色痕中的挥发性醇类组分和不挥发性红色颜料组分进行检测,以两者含量的比值作为考查指标绘制加热老化和光照老化两种人工老化方式下的老化曲线以及自然老化曲线,总结了印章色痕中醇类组分的挥发规律,为印章色痕形成时间的理化鉴定提供了一种可行的方法。
In this study,the volatile alcohols and non-volatile red pigments in seven kinds of ink seals were detected by Gas chromatography and High-performance liquid chromatography.The aging curve and natural aging curve were drawn under two artificial aging methods,heating aging and light aging,by using the ratio of the two contents as an index,and the volatility of the alcohols in the seal color traces was summarized.This study provides a feasible method for the physical and chemical identification of the formation time of color mark of seal.
