These columns are available in three proprietary HILIC phases (HILIC-A, HILIC-B and HILIC-N) developed to enable chromatographers to achieve reproducible and successful HILIC separations using a ...
WebHILIC selectivity. Stationary phase characteristics can be illustrated by 2-D radar graphs, which allow a simple visual assessment and comparison of column selectivity. Each axis of the radar plots below represents one of the following parameters: α (CH2) – degree of hydrophobicity. α (OH) – degree of hydrophilicity.

WebHILIC requires mobile phases that are highly volatile ( 80% organic), are ideal for compound ion- ization by ESI-MS, and can retain highly polar analytes. The term hydrophilic inter- action chromatography was first coined by Andrew Alpert to distinguish this technique from normal-phase chromatography (17). WebThe 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). Detection was performed using the Thermo Scientific ™ Vanquish Diode Array Detector HL with a LightPipe™ 10 mm standard flow
