A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...

A simple, rapid, and sensitive method for the detection of posaconazole using dispersive liquid-liquid microextraction (DLLME) coupled to surface-assisted laser desorption/ionization mass spectrometric detection (SALDI/MS) was developed. After the DLLME, posaconazole was detected using SALDI/MS with colloidal gold and α-cyano-4-hydroxycinnamic acid (CHCA) as the co-matrix. Under optimal extract...
