Determination of Eugenol Residue in Aquatic Using Dispersive Liquid-Liquid Microextraction Based on the Solidification of a Floating Organic Droplet Followed by UHPLC-MS/MS
A novel dispersive liquid-liquid microextraction based on solidification of floating organic droplet(DLLME-SFO)followed by ultra performance liquid chroma-tography tandem mass spectrometry(UHPLC-MS/MS)was developed for the determination of eugenol residue in aquatic.The influence of extraction parameters including types of extraction solvent,volume of extraction solvent,vortex extraction time,sodium chloride mass fraction,chromatographic condition and mass spectrometry condition were investigated.The optima...
