Use SeQuant® ZIC®-pHILIC HPLC Columns for More Difficult Separations of Polar Hydrophilic Compounds.

SeQuant® ZIC®-pHILIC HPLC columns are the preferred choice when extreme eluent conditions are needed to overcome challenging separations of polar hydrophilic compounds. Offering excellent pH stability from pH 2 to 10, these polymer-based columns carry densely bonded, truly zwitterionic functional groups with a charge balance of 1:1. This results in straightforward and reproducible separations with wide-spectrum pH tuning for optimal separation selectivity and detection sensitivity. Furthermore, SeQuant® ZIC®-pHILIC columns minimize background noise in evaporative detection techniques with high sensitivity to ions, such as charged aerosol detectors (CAD). SeQuant® ZIC®-pHILIC columns are available with 5 µm polymer particles in various formats of analytical dimensions. Alternative choices for the separation of polar hydrophilic compounds include silica-based SeQuant® ZIC®-HILIC columns with identical functional groups, and SeQuant® ZIC®-cHILIC columns with complementary selectivity.

What is HILIC?

HILIC 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 uses reversed-phase type eluents. Thus, it unites the benefits of aqueous mobile phases with separation based on normal phase principles in which more polar compounds respond with higher retention. This results in more efficient separation. Furthermore, HILIC is easy to combine with a wide range of detection methods, and boasts improved sensitivity with some of these techniques, such as electrospray ionization mass spectrometry (ESI-MS).
