WebHydrophilic interaction liquid chromatography (HILIC), although not a new technique, is unfamiliar to many chromatographers. HILIC uses the same mobile phases and systems … WebSyncronis HILIC stationary phase carries a zwitterionic functional group of the sulfobetaine type, monomerically bonded to highly pure, high surface area silica. The sulfobetaine zwitterion has both positive (quaternary ammonium) and negative (sulfonic acid) groups in a 1:1 ratio, so that the net surface charge is zero. Due to counterbalanced ...
WebApr 10, 2014 · This single-extraction HILIC approach was successfully used to characterize the endometabolism of Gram-negative and Gram-positive bacteria as well as mammalian macrophages. The extraction and ionization efficiency of MeOH/EtOH/H2O HILIC approach encompasses both the polar and nonpolar fractions from Bligh and Dyer extraction WebTo elucidate the metabolites associated with the larval exsheathment we applied: hydrophilic interaction liquid chromatography (HILIC) to separate the polar compounds; ultra-high-performance...
WebNov 5, 2024 · LC-MS with negative HESI gave another 45 unique compounds, while the HILIC/positive HESI gave a further 21 unique compounds, the latter being polar compounds with low molecular weights. A total of 50 compounds not previously noted in tobacco smoke were identified overall. WebChromatography (HILIC) at low pH with positive mode LC/MS detection was found to give the best overall sensitivity and chromatographic performance. The Agilent InfinityLab Poroshell 120 2.7 µm HILIC-Z and HILIC-OH5 chemistries offer two excellent options for LC/MS of amino acids. Both give complete separation of the challenging
