【摘要】：建立了一種基于非水毛細管電泳法區(qū)分藍色圓珠筆油墨的方法。確定了筆跡中堿性染料(結晶紫、甲基紫、堿性品藍、羅丹明6G、堿性艷藍B和堿性艷藍BO)的分離條件:緩沖溶液為1.00mmol/L醋酸-100mmol/L醋酸銨的甲醇-水(體積比90:10)體系,分離電壓和溫度分別為25kV和25℃,檢測波長為214nm。通過該方法分析了96支藍色圓珠筆中的油墨,并依據(jù)油墨中所含的染料種類對圓珠筆進行分類,同一類筆又通過聚類分析計量學方法再次進行區(qū)分。該法重復性好,結果準確可靠,為圓珠筆字跡鑒定提供了一種科學的方法。
[Abstract]:A method for distinguishing blue ballpoint pen ink based on non-aqueous capillary electrophoresis was established. The separation conditions of basic dyes (crystal violet, methyl violet, basic standard blue, Rhodamine 6G, alkaline brilliant blue B and alkaline brilliant blue BO) were determined. The buffer solution was 1.00 mmol / L acetic acid-100 mmol / L ammonium acetate methanol-water system (90:10 volume ratio). The separation voltage and temperature are 25 kV and 25 鈩，
