Solid phase extraction cartridges, Bond Elut™ C18 OH

Supplier: VARIAN

Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Solid phase extraction cartridges, Bond Elut™ C2

Solid phase extraction cartridges, Bond Elut™ C2

Supplier: VARIAN

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.
