| Abstract: |
| A gas chromatography-tandem mass spectrometric method was developed for the determination of 9 nitrogen containing compounds in marine fuel oil.The sample was purified with SPE cartridge to remove the saturated hydrocarbon,and then eluted with a mixed solution composing of dichloromethane and ethanol(5∶1).The target ingredients were separated on a DB-5MS column(30 m×0.25 mm×0.25 μm),detected in multiple reaction monitoring mode(MRM),and quantified by the external standard method.The method indicated a perfect performance in chromatographic separation.The linear ranges of 9 nitrogen containing compounds were between 1 mg/kg and 1 000 mg/kg,and the limits of quantitation were between 0.18 mg/kg and 0.43 mg/kg.The recoveries ranged from 85.3% to 121.6%,with relative standard deviations(RSDs,n=6) less than 6.8%.This method was rapid,accurate,precise and convenient to operate,and it was appropriate for the determination of 9 nitrogen containing compounds in marine fuel oil. |
