Epic Biphenyl Prep LC Columns - 250 mm, 20 mm I.D., 5 μm

Epic Biphenyl is a truly unique stationary phase with properties significantly different than ODS phases. This unique character results from bonded biphenyl groups, covalently attached to high purity silica, imparting a π-π electron interaction which produces an enhanced retention for many compounds particularly those that contain polarizable electrons. Many classes of compounds contain polarizable electrons including halogenated compounds, aromatics, nitro aromatics and conjugated systems.

The Epic line our latest range of LC columns, based on high density monomerically bonded phases produced through a proprietary bonding process. Epic HPLC and UHPLC columns are compatible with a wide range of organic modifiers and buffers and stable over a wide pH range. All Epic products use an ultra-high purity metal free silica and undergo strict quality control testing. For flexibility, we offer a wide range of column sizes as well being fully scalable from analytical to preparative dimensions.

Features and Benefits:

  • Ultra-high purity silica for improved peak shape, especially for basic compounds
  • Extensive range of stationary phase chemistries with innovative bonding chemistry to enhance method development
  • High density bonding produces columns with better pH stability, increased sample loading and better lot-to-lot reproducibility
  • Extended pH stability across commonly used mobile phase buffers
  • Microbore to preparative dimensions available to allow flexibility and full scalability
