Abstract

Objective: To establish a high performance liquid chromatography-tandem mass spectrometry method for the determination of Bisphenol A in laminated films and pouches for pharmaceutical packing. Methods: A C18 column was used with methanol-water (80∶20) as the mobile phase. After ultrasonic extraction with ethanol, the sample was filtered and analyzed by high performance liquid chromatography-tandem mass spectrometry. Results: Bisphenol A showed a good linear relationship within the concentration range of 0.004 992-0.099 840 μg·mL-1 (r=0.999 3). The limit of detection and limit of quantification were 0.001 498 μg·mL-1 and 0.004 992 μg·mL-1, respectively. The spiked recovery was 96.9% with an RSD of 2.0% (n=6). Conclusion: The method is specific and sensitive, has accurate results and good repeatability, and can be used for the determination of Bisphenol A in pharmaceutical packaging materials.
