【摘要】 <正>本研究用高效液相色谱法分析了89支蓝色圆珠笔的油墨成分。对色谱条件进行了优化,选择了580 nm,610 nm,670 nm三个检测波长。使用HPLC-MS确定了染料和染料之间的降解关系。发现蓝色圆珠笔中主要更多还原

【Abstract】 In this paper,inks from 89 blue ballpoint pens of different brands were examined by RP-HPLC method with multi step gradient elution.HPLC-MS method was used to identify dyes and their degradation relation.PCA were used to perspect the relationship of pens.Three wavelengths data is more potent in the classification as compared with single data,and consequently is more likely to reveal the data structure of inks.更多还原
