| Abstract: |
| A headspace gas chromatography-mass spectrometric method was developed for the determination of 14 organic solvent residues in newspaper.The target compounds were separated on a Capillary column(Agilent HP-INNOWAX，60 m×250 μm，0.25 μm)，and detected by the mass spectrometry in selected ion monitoring(SIM) mode.The calibration curves were linear in the range of 2-20 μg，with correlation coefficients not less than 0.995.The limits of detection (LOQ，S/N=10) of fourteen compounds were all less than 0.01 mg/m2.The average recoveries ranged from 86.6% to 101.8% at spiked levels of 3.97-16.28 μg with relative deviations(RSDs，n=6) not more than 6.8%.The method was rapid，accurate and sensitive，and was suitable for the determination of organic solvent residues in newspaper. |
