IntroductionIonic liquids have attracted much attention as an extraction solvent instead of traditional organic solvent in single‐drop microextraction. However, non‐volatile ionic liquids are difficult to couple with gas chromatography. Thus, the following injection system for the determination of organic compounds is described.
ObjectiveTo establish an environmentally friendly, simple, and effective...
Hydrodistillation (HD) coupled with headspace single-drop microextraction by using ionic liquid (IL) as the extraction solvent, followed by gas chromatography analysis technique, was successfully developed to determine the volatile and semivolatile compounds in seeds of Cuminum cyminum L. In the proposed method, a 1.5-μL microdrop of 1-octyl-3-methylimidazolium hexafluorophosphate, working as the...
