Abstract:
Two different offline 2-D hydrophilic interaction chromatography (2D-HILIC/HILIC) systems have been developed. In the two systems, a click maltose column was used in the first dimension, an amide column or a click beta-CD column was used in the second dimension, respectively. Both of the systems were used for the analysis of very polar components in Carthamus tinctorius Linn., which is a traditional Chinese medicine. Excellent orthogonality and separation results were obtained in both 2D-HILIC/HILIC systems, while the peak capacity of the system based on click maltose and amide column was higher for its adoption of stationary phase with smaller particle size in the second dimension.

Chromatography: Introduction
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
