| Abstract: | In this work, a preconcentration and ion chromatography method for the determination of trace anions on the surface of hard disk has been developed. Trace anions on the surface of magnetic head samples were washed with DI water, and then the anions was determined by IC with preconcentration technique. The chromatographic conditions were as follows： the analytical column was IonPac AS 12A anion-exchange column, Carbonate was used as the eluent at a isocratic flow rate, the detection was performed by a suppressed conductive detector.. Using this method, trace anions on the surface of hard disk sample was determinated and the recovery was between 96% and 104%. The proposed method is simple, and has high sensitivity and good selectivity. |
