| Abstract: | Objective To establish HPLC method for identifying environment-friendly ink and imprints.Methods Samples were extracted by ultrasonic extraction and centrifugation.ZORBAX Eclipse Plus Phenyl-Hexyl column（4.6mm×50mm,1.8μm） was used for gradient elution.The mobile phase consisted of ammonium acetate（20mmol/L）： acetonitrile,and the flow rate was 1.0 mL·min-1.Results The characteristic chromatogram peaks of 7 inks and their imprints are obtained.Conclusions The method is simple,efficient.It can be used for the determination of environment-friendly red ink and imprints samples. |
