SeQuant(R) ZIC-HILIC(TM) Guard Kit 20 x 2.1 mm

Descrição detalhada : The SeQuant(R) ZIC(R)-HILIC Guard column protects your analytical column from contamination. The guard column kit contains 3 Guard columns including the coupler.SeQuant(R) ZIC(R)-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(R)-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(R)-HILIC Column overall neutral, with weak, but important, ionic interactions. Tuning of the selectivity on the ZIC(R)-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.Thanks to their favorable retention and robust performance, SeQuant(R) 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(R) ZIC(R)-HILIC for analysis of melamine and related substances.SeQuant(R) 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
