This work describes the separation performance of a perhydroxylcucurbituril stationary phase for capillary gas chromatography. The perhydroxylcucurbituril stationary phase exhibits higher resolving capabilities for critical analytes with better peak shapes than cucurbituril and conventional stationary phases. The advantageous separation feature of the perhydroxylcucurbituril stationary phase may originate from its unique structure and favorably balanced interactions with the analytes. Also, the perhydroxylcucurbituril column shows good separation repeatability with relative standard deviations in the range of 0.01-0.13% for intraday, 0.37-0.82% for interday, and 1.0-4.7% for column-to-column repeatability.
Keywords: Capillary gas chromatography; Cucurbituril; Perhydroxylcucurbituril; Stationary phases.
