Development of LC/MS/MS Method for Screening and Quantitation of 47 Synthetic Dyes under Restricted Substance List in Textiles

摘要

A fast and highly sensitive LC/MS/MS method has been developed on LCMS-8040 for screening and quantitation of 47 restricted or banned synthetic dyes, including 23 azodyes, 21 disperse dyes and 3 basic dyes. The total run time of themethod is less than 20 mins. The LOQs of the method for these dyes are at 0.1～4.1 ng/mL, which are fully complied with the current regulatory requirements.
