Determination of 6PPD-quinone & alternative PPD-quinones in fish tissue using QuEChERS with Serial Push-Thru Cartridge Cleanup

6PPD-quinone (6PPD-Q) is an ozonation by-product of the tire antioxidant 6PPD, which emerging research shows poses a significant threat to aquatic ecosystems. As the concern over this class of contaminants grows, developing methods to extract and analyze various matrices is of the utmost importance.

Find out more about a QuEChERS extraction of a subset of PPD-Qs in salmon, combined with push-thru cartridge clean-up using UCT’s Quick QuEChERS^®, C18, and LipiFiltr^® in series to achieve the best level of sensitivity in the fatty matrix. Discover how by using UCT’s SelectraCore^® C18 HPLC Column, an optimized analysis method was developed on LC-MS/MS.
