General description

SeQuant^® ZIC^®-HILIC Columns are designed to retain and separate all types of polar and hydrophilic compounds and for robust chromatography with high selectivity and reproducibility. The silica-based ZIC^®-HILIC sorbent has a bonded stationary phase consisting of a highly polar, permanent zwitterion. Separation selectivity is favored by the 1:1 zwitterion charge balance, which makes the ZIC^®-HILIC Column overall neutral, with weak, but important, ionic interactions. Tuning of the selectivity on the ZIC^®-HILIC Column during method development is facilitated by the pH-inpendent permanent zwitterion, ensuring that only the analytes (and not the column) are affected during eluent optimization.The Pore size of 100 Å makes this column perfectly suitable for the separation of small polar molecules under HILIC conditions.The column dimension of 150 mm length x 4.6 mm ID is the best choice for the separation of polar compounds using a standard HPLC Instrument.Thanks to their favorable retention and robust performance, SeQuant^® HILIC columns have become extremely popular in numerous laboratories around the world. For example, US FDA (United States Food and Drug Administration) has recommended SeQuant^® ZIC^®-HILIC for analysis of melamine and related substances. SeQuant^® HILIC columns excel in stability and low bleed. These features make them particularly suitable for LC-MS applications where high background can lead to signal suppression and interference with quantitative measurements while also increasing instrument wear. Their high stability makes these high-performance HILIC columns also attractive for traditional HPLC applications.Learn more about the Supelco HPLC Column portfolio and Method development:Brochure: HPLC and UHPLC Column Selection Guide Brochure: A Practical Guide to HPLC - Method Development Guide
