英文摘要hydrophilic interaction chromatography (hilic) was used in two dimensions in a comprehensive two-dimensional hilic hyphenated with a quadrupole time-of-flight mass spectrometry (hilic x hilic-q-tof-ms) system for the analysis of complex samples of hydrophilic compounds. a tskgel amide-80 column was employed as the first dimension, and a short polyhydroxyethyl a column was as the second dimension. the column system showed moderate orthogonality at defined operational conditions. a high speed q-tof-ms detector as a third complementary dimension significantly improved the peak capacity. the separation capability of the developed hilic x hilic-q-tof-ms system was tested by separating an extract from quillaja saponaria. the major components, quillaja saponins, in the extract were well identified by means of [m-h](-) ions, characteristic product ions, and their two-dimensional retention behaviors. several pairs of isomers, which were often co-eluted on conventional lc-ms methods and had similar fragmentation characteristics in ms/ms spectra, were well separated on the two-dimensional system based on their different hydrophilicity. the developed comprehensive two-dimensional hilic system demonstrates unique selectivity for hydrophilic compounds and satisfactory peak capacity and resolution for analogues by making sufficient use of two-dimensional separation plane.
