A method is described for the determination of the content of the liquid phase in packings for gas-liquid chromatography. It is shown that the extraction method is subject to an error due to the solubility of some inorganic compounds of the support. A more satisfactory method involves the evaporat
Headspace liquid-phase microextraction (HS-LPME) has been applied to efficient enrichment of phenols such as 2-nitrophenol, 4-chlorophenol, 2,4-dichlorophenol, and 2-naphthol from water samples based on 1-butyl-3-methylimidazolium hexafluorophosphate ([C4MIM][PF6]) as an extractant. Some parameters
