Abstract:

A method for the determination of 17 sulfonamides residues in infant formula by accelerated solvent extraction (ASE) and ultra-high performance liquid chromatography/mass spectrometry (UHPLC-MS/MS) was developed. The linearity, sensitivity, recovery rate and matrix effect of the method were verified. Meanwhile, the screening analysis for 17 sulfonamides in infant formula collected from the market was carried out. The results showed that the linearity of sulfonamides were in the range of 0.5-100 μg·kg-1, and the correlation coefficient was greater than 0. 998, the recoveries were 75.3%-103.6%, the relative standard deviation was less than 11.0%, the matrix effect was 0.4-1.0, the detection limit for sulfonamides in infant formula was 0.1-3.0 μg·kg-1, and the limit of quantification (LOQ) was 0.3-10 μg·kg-1. The developed method has the merits for convenient extraction, high sensitivity and accuracy, and the method can simultaneously determine 17 sulfonamides residues in infant formula.

Key words: accelerated solvent extraction (ASE), ultra-high performance liquid chromatography/mass spectrometry (HPLC-MS/MS), infant formula, sulfonamides
