Abstract
AbstractThis work firstly reported a new polycaprolactone based material functionalized with guanidinium ionic liquid (PCL‐GIL) as the stationary phase with high resolution performance for capillary gas chromatography (GC). It is composed of polycaprolactone (PCL) and guanidinium ionic liquid (GIL) with amphiphilic conformation. The PCL‐GIL capillary column coated by static method exhibited high column efficiency of 3942 plates/m and moderate polarity. As a result, the PCL‐GIL column exhibited high‐resolution capability. For a mixture of 27 analytes with a wide ranging polarity and outperformed the PCL‐2OH and HP‐35 columns, showing its advantageous separation capability for analytes of diverse types. Moreover, the PCL‐GIL column showed high resolving capability for various positional isomers and cis‐/trans‐isomers, including alkylbenzenes, chlorobenzenes, naphthalenes, bromonitrobenzenes, chloronitrobenzenes, benzaldehydes, phenols, alcohols, respectively. In a word, PCL derivatized by GIL units as a new type of stationary phase has a promising future in GC separations.
