反相HPLC法鉴别蓝圆珠笔油墨的种类

Determining the Differentiation of the Species of Ballpoint Pen Inks by Reversed Phase HPLC

采用反相高效液相色谱法对全国各地生产的不同厂家及不同生产批号的圆珠笔油墨种类进行鉴别研究之后可以发现,由于不同种类的圆珠笔油墨所呈现的色谱峰的保留时间及相对峰高比各不相同,因此,可以对圆珠笔油墨种类进行鉴别。

This paper introduces a technique th at can identify the differentiation of the species of ballpoint pen inks that come from dif ferent manufactures and different batch numbers by reversed phase High Pressure Liquid Chromatography.We can identify the species of ballpoint pen inks by their retention time and radio of peak height ?So,the authentic evidence for identify ing the differentation of the specie s of ballpoint pen inks is provided by thi s methed in the field of forensic scie nce?
