Recent progress of chiral stationary phases for separation of enantiomers in gas chromatography.
Journal of Separation Science, 2017Chromatography techniques based on chiral stationary phases are widely used for the separation of enantiomers. In particular, gas chromatography has developed rapidly in recent years due to its merits such as fast analysis speed, lower consumption of ...

Multidimensionality in gas chromatography
TrAC Trends in Analytical Chemistry, 1996Many analytical problems require more resolution than a single chromatographic technique can provide. In such cases the separation power can be enhanced by using more than one separation technique or mechanism. The sample is then dispersed in different time dimensions.
