Résumé
Extraction experiment of volatile compounds in disposable syringes from five manufacturers was undertaken by GC-MS with high-space injection and semi-volatile compounds were tested by GC-MS.MS detection ranged from 30 to 650 with electron ionization (EI) source.Vanillin was used as internal standard to monitor the sample pretreatment process.Liquid-liquid extraction (LLE) and solid-phase extraction (SPE) were compared to acquire a simple processing method with more extractables in syringe materials.HCl,NaOH,Tween 80 and ethanol-aqueous solution were used as extraction solvents.The method was successfully developed to determine the unknown volatile extractables and the results were used to investigate the safety of disposable syringes comprehensively.
