Atlantis Silica HILIC Column, 100Å, 3 µm, 2.1 mm X 30 mm, 1/pk

Atlantis HILIC Silica columns are employed in conjunction with high organic mobile phases (>80% acetonitrile) to retain analytes that are simply too polar for reverse-phase chromatography to retain. In comparison to typical chromatographic reversed-phase techniques, HILIC separation processes enable orthogonal analyte selectivity.

Using Hydrophilic Interaction Chromatography, the Atlantis Silica HILIC Column can easily separate and retain extremely polar, water-soluble basic chemical molecules. Peptides, metabolites, and actives are examples of these molecules. HILIC has increased LC/ESI-MS performance and direct compatibility with SPE solvents, in addition to retaining extremely polar molecules. It also provides complementing selectivity when compared to reversed-phase HPLC.

Reversed-phase chromatography has a tough time retaining and separating very basic polar analytes. This is because they are hydrophilic and have a net positive charge at acidic pH. The Atlantis Silica HILIC Column is the appropriate lab equipment for use in metabolism, drug discovery, and combinatorial chemistry since HILIC solves these difficult separation challenges.

You can maintain highly polar basic analytes with volatile mobile phases that are suited for compound ionization by ESI-MS using the Atlantis Silica HILIC Column. This means you'll receive results with higher sensitivity and lower detection limitations. This is particularly important in drug metabolism research because metabolites are generally more polar than their parent chemicals and are present in much lower concentrations.
