Ionic liquids (ILs) are a class of organic salts that meet many of the requirements of GC stationary phases including high thermal stability, high viscosity, and tunable selectivity through the modification of the chemical structure. IL-based columns, when incorporated either in the first or second dimension, can offer unique selectivity compared to polydimethyl(siloxane) and poly(ethyleneglycol) derived GC stationary phases for the separation of complex samples by multidimensional gas chromatography. In addition, IL-based columns are emerging as superior choices for applications requiring high polarity as well as high thermal stability. The present contribution provides an overview on IL-based stationary phases for multidimensional gas chromatography with an emphasis on developments in the period from 2012 to early 2018. The analysis of various analytes (e.g., fatty acids, polycyclic aromatic sulfur heterocycles, and biodiesels) in complex matrices as well as the developments of new IL-based stationary phases for multidimensional gas chromatography are described.

离子液体（ILs）是一类有机盐，可满足GC固定相的许多要求，包括高热稳定性，通过改变化学结构，具有高粘度和可调节的选择性。基于IL的色谱柱在第一维或第二维中结合使用时，与通过多维气相色谱法分离复杂样品的聚二甲基（硅氧烷）和聚（乙二醇）气相色谱固定相相比，可以提供独特的选择性。此外，对于需要高极性和高热稳定性的应用，基于IL的色谱柱正在成为首选。本文稿概述了多维气相色谱法基于IL的固定相，重点介绍了2012年至2018年初的发展情况。各种分析物（例如脂肪酸）的分析，多环芳族硫杂环化合物和生物柴油）在复杂基质中的应用，以及用于多维气相色谱的新型基于IL的固定相的开发进行了描述。
