ExSil® 1400

Dr. Maisch Exsil 1400 NH2 Analytical HPLC Column, 1400 Å, 5 µm, 4.6 x 250 mm, 1/Pk

Product Number: 6136951.s2546

This column uses a stationary phase with amino functional groups (-NH2). These columns are designed for the separation and analysis of polar and moderately polar compounds. The "Exsil" part of the name indicates it's part of the Exsil range, which is known for its alternative silica-based HPLC phases.

• NH2 (Amino): The "NH2" indicates that the stationary phase of the column is modified with amino groups (-NH2). These groups are chemically bonded to the silica support of the column.
• Functionality: Amino columns (NH2) are commonly used for the separation of polar and moderately polar compounds, including sugars, carbohydrates, and some pharmaceuticals. They can also be used in HILIC (hydrophilic interaction liquid chromatography) mode.
• Selectivity: The presence of amino groups provides a different selectivity compared to reversed-phase columns, allowing for the separation of compounds that may not be easily separated using other types of columns.
• Exsil 1000: Columns with a pore size of 1400 Å Angstroms (140 nm)
