Application of Liquid-phase Microextraction Based on Solidification of Floating Organic Droplet Coupled with Gas Chromatography in the Analysis of Pesticide Residues
Conventional sample preparation methods such as liquid-liquid extraction and solid phase extraction, are time-and solvent-consuming, and often involve several complicated procedures. A novel liquid phase microextraction (LPME) based on solidification of floating organic droplet (LPME-SFO) has been recently developed which was based on the distribution of the analytes between microliters volume of the extraction solvent (floating on the surface of the aqueous sample) and the aqueous sample matrix.
