Bond Elut CN-U is ideally suited for the extraction of polar compounds from a nonpolar matrix, such as hexane or oils. It is suitable for very polar analytes that may be irreversibly retained on SI or Diol (2OH) SPE phases.

• Ideal for extracting aqueous analytes
• Retention in aqueous and organic matrices
• Useful for many applications

A medium polarity sorbent with many uses, it is ideal for applications in which extremely nonpolar compounds would be irreversibly retained on high carbon load sorbents, such as C8 and C18. This endcapped version of the cyano sorbent is best utilized when extracting analytes from an aqueous matrix.
