摘要:Abstract(#br)A novel multiple extraction (ME) process integrated heat reflux extraction (HRE) with cyclohexanone (CYC) followed by ultrasonic assisted extraction (UAE) with N -methyl-2-pyrrolidone/CS 2 (NMP/CS 2 ) mixed solvent was developed for extraction of four different r...

摘要:Abstract(#br)This paper proposes a new optimization strategy for the extraction of volatile compounds from honey samples using headspace solid-phase microextraction (HS-SPME) and separation/detection by gas chromatography–mass spectrometry (GC–MS). The new optimization stra...

摘要:Abstract(#br)Theoretical aspects of multiple solid-phase microextraction are described and the principle is illustrated with the extraction of lidocaine from aqueous solutions. With multiple extraction under non-equilibrium conditions considerably less time is required in order t...
