A procedure for using ionic liquids to determine volatile impurities in compounds or matrices that are soluble in an ionic liquid is described. Using a conventional autosampler a droplet of ionic liquid solution is suspended in the inlet of the gas chromatograph and analytes are desorbed onto a GC column using splitless injection conditions. Results are presented for 1,2-propanediol, nonane, N,N-dimethylacetamide, and mesitylene in two different compounds in the ionic liquids trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide and trihexyltetradecylphosphonium dicyanamide.
描述了一种使用离子液体测定可溶于离子液体的化合物或基质中挥发性杂质的方法。使用传统自动进样器将一滴离子液体溶液悬浮在气相色谱仪的进样口中，并在不分流进样条件下将分析物解吸到气相色谱柱上。给出了在离子液体三己基十四烷基鏻双（三氟甲基磺酰）亚胺和三己基十四烷基鏻二氰胺中的两种不同化合物中1,2 - 丙二醇、壬烷、N，N - 二甲基乙酰胺和均三甲苯的结果。
