Dispersive Liquid-Liquid Microextraction GC Method

Researchers from National Tsing Hua University (Hsinchu, Taiwan) developed a dispersive liquid?liquid microextraction (DLLME) method based on solidification of a floating organic drop and combined it with gas chromatography with either electron-capture or mass spectrometry detection.

Researchers from National Tsing Hua University (Hsinchu, Taiwan) developed a dispersive liquid–liquid microextraction (DLLME) method based on solidification of a floating organic drop and combined it with gas chromatography with either electron-capture or mass spectrometry detection. The method reportedly is simple, inexpensive, and precise. It also avoids the use of high-toxicity solvents usually used in DLLME. They used halogenated organic compounds in water as the model compounds for the method.
