Abstract
|
|
|
|
Twenty-one allergy-induced aromatic material in children's products were analyzed using gas chromatography mass spectrometer(GC-MSD). The analytes were extracted using an automatic Soxhlet extractor, centrifuged for 10 minutes in a fast freezing centrifuge, and the supernatant was filtered with a syringe filter and then transferred into a 2 mL vial and injected in a split mode. In the established condition, the calibration curve showed linearity with a determination coefficient of 0.9981 or more. Sensitivity was 0.3145 ~ 1.6757, which showed a fairly wide range of sensitivity for each substance. The detection limit of the device was 0.0016 ~ 0.0423 ㎍/mL and the maximum detection limit was less than 0.05 ㎍/mL. The method detection limit ranged from 0.0030 ~ 0.0589 ㎍/mL. In addition, the limit of quantification ranged from 0.0096 to 0.1876 ㎍/mL, with precision ranging from 0.41 to 10.49 % and accuracy ranging from 83 to 116 %. The analytical method developed in this study was applied to commercial products.
