Ultisil HILIC Amide 120Å Series

HILIC (Hydrophilic Interaction Liquid Chromatography) is a separation mode achieved through the partitioning of polar solutes from high concentration, water-miscible, organic mobile phase into hydrophilic surface environment. Welch Ultisil HILIC Amide column is a special column designed for HILIC mode. As amide group has strong hydrophilicity, stability and electrically neutral, Ultisil® Amide has longer life, better separation repeatability and peak shape than NH2 phase does.

• Based on silica bonded with amide groups, appropriate for the separation of hydrophilic samples
• Multiple actions such as hydrogen bond, molecular and electrostatic interactions
• Good compatibility with many kinds of detectors, such as MS detector
• Stable in organic mobile phase that contains water
