Weborganic solvent content > salt content ~ pH > column temperature On this basis, the first and most important parameter to optimize is the organic solvent content. As already emphasized, the mobile phase in HILIC is constituted by a mixture of water– water miscible organic solvent, such as in RPLC. WebHILIC silica column designed for increased retention of polar compounds without ion-pairing reagents. 2.7 µm Raptor core-shell particles provide the speed of SPP, with greater efficiency and capacity than 5 µm particles. Ideal for increasing sensitivity and selectivity in …
Webretained on the reversed-phase column where separation will occur according to the ON length, type, and presence of chemical modifications. Proper selection of the mobile phase is of utmost importance. The mobile phase is prepared by mixing the amine ion pairing reagent with an acidic counterion in water at a well defined concentration and ratio. WebThe analysis was carried out on a Diol HILIC column using a mobile phase consisting of acetonitrile and solution of 10 mmol/L citric acid adjusted with 1-propylamine to pH 5.5 in ratio...
WebA hydrophilic interaction liquid chromatography method has been established for the quantification of ergothioneine (EGT) in fermentation broth. Chromatographic separation was conducted on a Venusil hydrophilic interaction liquid chromatography (HILIC) column (250 × 4.6 mm, 5 m) at an elution rate of 1.0 mL/min with an isocratic mobile phase ... Web“HILIC” stands for Hydrophilic Interaction Liquid Chromatography. It is a separation mode that uses a polar stationary phase, which can be bare silica, like the Raptor HILIC-Si …
