OBJECTIVE：To establish a method for determination of trace platinum in zolpidem tartrate. METHODS： Graphite furnace atomic absorption spectrometry （GFAAS） was adopted for direct determination after dissolving sample in 1％ Hydrochloric acid solution. Horizontal platform graphite tube was performed with detection wavelength of 244.79 nm， slit width of 0.2 nm and current intensity of hollow cathode lamp of 6 mA. The mode of background correction was zeeman effect， the peak height was used as measurement pattern， and the injection volume was 20 μl. RESULTS： The linear range of platinum was 0-100 ng/ml （r＝0.999 0）； RSDs of precision and reproducibility tests were no more than 2.0％； recovery was 97.78％-103.07％ （RSD＝1.6％，n＝9）； the detection limit was 1.48 ng/ml. CONCLUSIONS： This method is simple and rapid with good precision and accuracy， and can be applied for the determination of trace platinum in zolpidem tartrate.
