摘　　要：建立了黑色圆珠笔油墨字迹色痕的高效液相色谱法的分析条件和实验方法,采用乙腈-NH4HCO3溶液(10 mmol/L)(体积60∶40)为流动相,检测波长580 nm,同时利用质谱法作为佐证。在此条件下对市售的51支不同生产厂家和品牌黑色圆珠笔油墨的字迹色痕进行了分析,根据油墨中所含染料成分的差异将其分为6大类,考察了纸张的影响及在该分析条件下结果的精密度和重复性。A high performance liquid chromatography （HPLC） method was established to analyze black ballpoint pen inks by using acetonitrile-NH4HCO3 （ 10 mmol/L） （60 ： 40, by volume） as mobile phase and detecting at 580 nm. Mass spectra（MS） were used to further recognize structures of dye compounds in the inks. 51 different kinds of black ballpoint pen inks from different manufactures were classified into six different categories depending on the disparities of their dye components. The influence of 10 different types of papers on dye determination was discussed, and the precision and repeatability of the method were investigated under optimized experimental conditions.
