Fluorescently labeled N-glycans were analyzed by HILIC-UHPLC-FLR on a Waters Acquity UPLC instrument (Waters, USA), which consisted … HILIC is a chromatographic technique for the retention and separation of problematic polar compounds. In HILIC mode, water acts as the strongest solvent to effectively elute analytes off the column, and the organic solvent acts as the weak solvent. This is opposite to reversed phase chromatography. See more HILIC phases retain polar, hydrophilic compounds that are not retained on standard reversed phase columns. For mass spectrometry … See more Our HILIC columns are ideal for analyzing highly polar molecules such as urea, biurea, choline and butyrobetaine, tromethamine, ascorbic acid and related compounds, folic acid and its metabolites, nicotine and its … See more
WebApr 14, 2024 · HILIC-UHPLC-FLR analysis. Fluorescently labeled N-glycans were analyzed by HILIC-UHPLC-FLR on a Waters Acquity UPLC instrument (Waters, USA), which consisted of a quaternary solvent manager, a sample manager, and an FLR fluorescence detector set with excitation and emission wavelengths of 310 and 370 nm, respectively. WebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase. Retention of these polar compounds using reversed phase methods is often difficult because of co-elutions with the solvent front or elutions within the chromatographic region where ion suppression is the greatest.

The technique combines the benefits of aqueous mobile phases, like reversed-phase HPLC, with separation based on normal phase principles. As a result, more polar compounds respond with higher retention resulting in more efficient separation. This makes HILIC the method of choice ...
