Hilic separation
WebHILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% … WebHILIC chromatography provides a clean, cost-effective separation method that can be easily incorporated into automated workflows for intact mass confirmation of oligonucleotides. …
Hilic separation
Did you know?
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.

WebThe separation achieved was similar on the 2 columns. However, the epinephrine/norepinephrine pair were slightly better separated on the Poroshell 120 HILIC column. Overall, the peaks were sharper on the Poroshell 120 HILIC column, and the last peak eluted at 3 minutes versus more than 6 minutes on the ZORBAX Rx-Sil column. … WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Simply put, HILIC is a normal-phase type of separation but …
Web1 day ago · Evaluation of zwitterionic HILIC separation. Zwitterionic stationary phases (zHILIC) are of particular interest for untargeted analysis of polar compounds, as their properties are significantly different from other HILIC materials. A very low net surface charge (as a result of a 1:1 molar ratio of oppositely charged functional groups) allows ... Websubsequent gradient separation. Diluted samples were aliquoted into sample vials and stored at 4°C in the Vanquish autosampler prior to analysis. Instrumentation The separation was achieved in HILIC mode by using the Accucore 150 Amide HILIC column. The column was operated by the Vanquish Flex Quaternary UHPLC system (Table 1 and Table 2).
WebDescription. Hydrophilic interaction liquid chromatography, or HILIC, is a powerful mode of liquid chromatography (LC)that uses polar stationary phases and high-organic initial mobile phase conditions for the separation of polar analytes. Join us as we explore HILIC …

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 fishwise jobsA typical mobile phase for HILIC chromatography includes acetonitrile ("MeCN", also designated as "ACN") with a small amount of water. However, any aprotic solvent miscible with water (e.g. THF or dioxane) can be used. Alcohols can also be used, however, their concentration must be higher to achieve the same degree of retention for an analyte relative to an aprotic solvent - water combination.
