ExSil® 100

Dr. Maisch Exsil 100 PEI Analytical HPLC Column, 5µm, 100Å, 4.6mm I.D. x 100mm Length, 1/Pk

Product Number: 6136882.s1046

• 100 Å
• 0.52 cc/g
• 208 m2/g
• Type A Silica and Bonded Phases
• Alternative to Spherisorb
• Available in 1.5, 3, 5 and 10 μm particle sizes
• Widest range of bonded phases

The original Exsil 100 range was developed to provide an alternative to Spherisorb type products. The extensive range of bonded phases includes novel phases such as the ODS-B and Octyl-B which are so deactivated that they can chromatograph strong bases in buffer free eluents. The range of phases continues to provide a comprehensive selection for all standard applications.

These columns utilize an ODS (Octadecylsilyl) stationary phase, which is a type of reversed-phase column commonly used for separating a wide range of compounds. Exsil ODS columns are designed as alternatives to the classic spherical HPLC silicas like Spherisorb.

This column uses a spherical silica-based media designed for various applications in liquid chromatography. PEI in the name refers to the chemical modification of the silica, Polyethyleneimine.

• PEI: Stands for Polyethyleneimine, a chemical used to modify the silica surface in the Exsil 100 PEI column.
• Bulk Media: Refers to the unpacked material, often used for packing columns.
• Spherical silica particles: Provide good column packing and flow properties.
• PEI modification: Offers unique selectivity properties, making it suitable for separating a range of compounds, including proteins and peptides.
• Robustness: The Exsil process produces silicas with good stability, including high pH stability.
• Exsil 100: Columns with a pore size of 100 Å Angstroms (10 nm)
