Reference: Determination of Four Amide Fungicides in Grape Wine by Gas Chromatography Coupled with Tandem Mass Spectrometry
Key Statements

Abstract-

To simultaneously determine the presence of four amide fungicides (amisulbrom, boscalid, fluopicolide, and silthiofam) in samples of grape wine, a method involving gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) was developed. Samples of the grape wine were diluted with water, after which they were purified and concentrated through solid-phase extraction, and analyzed using GC-MS/MS. Isotope-labeled internal standards were used to correct the matrix effects. The limit of detection (LOD) and limit of quantification (LOQ) of all four amide fungicides was 0.6 μg kg−1 and 2.0 μg kg−1. The average recoveries were in the range of 76.5–93.4% with relative standard deviations (RSDs) below 5.4%, which were measured at three concentration levels. Structural analysis of the four amide fungicides was carried out for the first time based on the MS/MS spectrogram of the compounds.
