Weba HILIC-UV/FLD method was developed and glycan identification was performed with LC-MS experiments. HILIC, paired with UV or fluorescence detection, provides a robust and unique detection tool for routine analysis (e.g. glycoform stability studies)—with retention times as qualitative and peak area as quantitative information.

WebThe instrument was injecting a small volume of the weak wash solvent (90:10 water:acetonitrile) along with the sample. This weak wash solvent is actually a strong wash solvent in HILIC mode. To determine if this wash solvent was causing the poor chromatography, the needle wash solvent bottles were reversed. Upon changing solvent … Webare recommended for use in HILIC due to their solubility in high acetonitrile concentrations and buffering capacity at low pH. Buffer concentrations of 2-18 mM are typically used. Step-by-Step Rational Method Development HILIC stationary phase and mobile pH are the two most powerful parameters for altering HILIC selectivity.
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 column, or a polar bonded phase, like the Raptor FluoroPhenyl column. WebJun 1, 2014 · Peptide drugs play a critical role in therapeutic treatment. However, as the complexity of plasma, determination of peptide drugs using liquid chromatography-tandem mass spectrometry (LC-MS/MS) is a daunting task.
