By using this method, a total of 108 blue ink samples have been divided to 18 groups depending on the main component. The spectral characteristics of these inks such as peak location, peak intensity etc. were described by the way of pattern recognition; and the species of inks have been able to be recognized by their correlation coefficient(λ). This system has provided a best reliable and nondestructive method for the determination of ballpoint pen ink.展开更多
应用高效液相色谱-电喷雾/质谱(HPLC-ESI/MS)分析88支市售蓝色圆珠笔油墨。液相色谱分离采用Xterra MS C_(18)柱,等度洗脱,正、负离子模式电离,结果表明油墨中含有碱性品蓝、罗丹明B、甲基紫、结晶紫、碱性艳蓝B、碱性艳蓝BO等碱性染料...应用高效液相色谱-电喷雾/质谱(HPLC-ESI/MS)分析88支市售蓝色圆珠笔油墨。液相色谱分离采用Xterra MS C_(18)柱,等度洗脱,正、负离子模式电离,结果表明油墨中含有碱性品蓝、罗丹明B、甲基紫、结晶紫、碱性艳蓝B、碱性艳蓝BO等碱性染料。实验发现碱性品蓝、碱性艳蓝B、碱性艳蓝BO和罗丹明B会发生脱烷基作用,证实油墨中含有新染料成分维多利亚蓝4R(Solvent Blue 2)。根据油墨中存在的染料成分将88支市售蓝色圆珠笔分成九类,为进一步鉴定圆珠笔书写时间,进而建立圆珠笔油墨库创造有利条件。展开更多
