ExSil® (Exmere) Exsil 100

Dr. Maisch Exsil 100 Octyl Analytical HPLC Column, 5µm, 100Å, 4.6mm I.D. x 300mm Length, 1/Pk

Product Number: 5136526.s3046

• 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.

• HPLC Column: Exsil 100 Octyl is a type of column used in HPLC, a technique for separating compounds in a mixture based on their differing interactions with a stationary phase (the column packing) and a mobile phase (the liquid solvent).
• Reversed-Phase: The "reversed-phase" aspect indicates that the stationary phase is non-polar (like the C8 chain) and the mobile phase is typically a polar solvent (like a mixture of water and acetonitrile).
• C8 (Octyl) Phase: The C8 phase is a hydrocarbon chain (octyl group) chemically bonded to the silica support of the column. This provides a hydrophobic (water-repelling) surface that interacts with non-polar compounds in the sample, causing them to elute (come off the column) later than more polar compounds.
• Applications: Exsil 100 Octyl columns are versatile and can be used for many applications, including pharmaceuticals, environmental analysis, and food chemistry.
• Deactivation: The Exsil 100 range, including the Octyl-B phase, is known for its high level of deactivation, allowing it to chromatograph strong bases even in the absence of buffer solutions.
• Exsil 100: Columns with a pore size of 100 Å Angstroms (10 nm)
