| titleOfInvention | Liquid chromatograph ultraviolet method measures 9 kinds of ultraviolet absorber specific transfer metering methods |
| abstract | The present invention provides a kind of and removes the high performance liquid chromatography of the specific gross migration of 9 kinds of ultraviolet absorbers in glyceride detection food contact material based on 1,1,3,3 tetramethyl guanidine organic facies anion-exchange solid phase extraction.Food simulants soaks testing sample, is cooled to room temperature and mixes, and aqueous-based food analogies oxolane 1:1 dilutes, sample introduction after hydrophilic polytetrafluoro acetic acid syringe filters filters；Vegetable oil food simulants uses based on 1, and the organic facies anion-exchange solid phase extraction of 1,3,3 tetramethyl guanidine removes glyceride, sample detection after eluting separation.Glyceride removal effect in the method vegetable oil food simulants is good, chromatographic isolation and linear relationship are good, the response rate and accuracy are high, and quantitative limit meets the EC regulations limitation requirement to 9 kinds of specific gross migrations of ultraviolet absorber, and has been applied to the detection of actual sample. |
