Complementary Selectivity for HPLC and LC-MS Separation of Polar Hydrophilic Compounds with SeQuant® ZIC®-cHILIC from Merck Millipore

19 Mar 2015

This brochure describes the advantages of using SeQuant ZIC-cHILIC for HPLC and LC-MS of polar hydrophilic compounds. This new zwitterionic stationary phase provides you with complementary selectivity for easier method development for substances that have been difficult to separate by previous types of HPLC columns operated in reversed-phase or HILIC mode.

SeQuant® ZIC®-cHILIC for HPLC and LC-MS separation of polar hydrophilic compounds

Merck KGaA, Darmstadt, Germany

This new zwitterionic stationary phase with phosphorylcholine functional group provides you with complementary selectivity for easier method development for substances that have been difficult to separate by previous types of HPLC columns operated in reversed-phase or HILIC mode. The selectivity features of SeQuant® ZIC®-cHILIC are especially beneficial for negatively charged polar compounds such as nucleotides and organic acids, but do also provide advantageous separations of positively charged hydrophilic molecules; for example aminoglycosides and cations.   The column is also very suitable for zwitterionic and neutral polar hydrophilic substances. High-performance HILIC column Complementary selectivity for polar hydrophilic compounds Maximum LC-MS compatibility with minimized column bleed Excellent reproducibility and robustness Very high stability (more than 1600 injections during 270 hours of continuous use without showing any signs of change in retention)

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
