| titleOfInvention | A kind of method of Polychlorinated biphenyls in quantitative analysis dry food wrapping paper |
| abstract | The present invention discloses a kind of detection method of Polychlorinated biphenyls in quantitative analysis dry food wrapping paper, this method is based on the content that gas-chromatography-tandem mass spectrometer measures 7 kinds of main Polychlorinated biphenyls substances in dry food wrapping paper, include the preparation of inner mark solution, standard working solution and sample solution, GC MS/MS analysis and the calculating of measurement result and etc..Detection method operation after the present invention is optimized is relatively simple, respond that sensitive, quantitative analysis is accurate, effectively reduce the interference come by sample substrate complicated band, used analytical instrument condition makes object be responded with preferable signal, and there is preferable linear dependence, the detection limit of 7 kinds of Polychlorinated biphenyls substances is respectively 0.99ng/g, 0.74ng/g, 1.05ng/g, 1.29ng/g, 0.75ng/g, 1.11ng/g and 1.19ng/g, repeatability<10%, recovery of standard addition is between 68.4%~147.0%.Illustrate the high sensitivity of this method, repeatability and the rate of recovery are preferable, are suitable for measuring the quantitative analysis of trace object in food dryness wrapping paper. |
