Agilent Technologies SPE-Kartusche Bond Elut-C2, 500 mg, 3 ml, 50 St/Pkg

Bond Elut C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.
