Hydrophilic Interaction (HILIC) Columns

Hydrophilic Interaction (HILIC) Columns Hydrophilic interaction chromatography (HILIC) columns are is used in the separation of polar compounds. HILIC utilizes a polar stationary phase and a mobile phase that is a mixture of water and a less polar organic solvent such as acetonitrile. Hydrophilic partitioning plays the largest role in the mechanism of retention for this method, with other interactions such as ion-exchange, hydrogen bonding, and dipole-dipole contributing to a lesser extent. HILIC is considered a complementary technique to normal and reverse-phase chromatography. Its advantages include enhanced detection sensitivity when used with mass spectrometry, and higher flow rates due to the low viscosity of the mobile phase. HILIC stationary phases can be divided into three different groups: neutral, charged, and zwitterionic phases. Browse various HILIC columns below and visit the supplier page for more details.

  • Fast, Easy-to-Use SEC Column for 5–650 kDa Proteins

    The Enrich SEC 650 column is an easy-to-use option for the size-dependent separation of proteins with a wide range of sizes. This column can tolerate NaOH concentrations of up to 0.5 M for overnight incubation, which facilitates thorough cleaning and the removal of contaminating endotoxins. One of the benefits is that the buffer flow rates and pressure limits allow for a maximum flow rate of 2 ml/min. This means we can effectively separate proteins at a speed of 1 ml/min, enabling rapid processing.

  • Versatile SEC Column for 10–600 kDa Proteins

    The Superdex 200 Increase is a column made from agarose-dextran that enables size-dependent separation of proteins. It effectively separates proteins based on their size and offers excellent resolution specifically in the 100-300 kDa range. This column can withstand NaOH concentrations of up to 0.5 M for overnight incubation, facilitating thorough cleaning and the removal of contaminating endotoxins. However, a limitation is that the buffer flow rates and pressure constraints allow us to operate only up to approximately 0.6 ml/min.
