Bond Elut C18 EWP features wide pores, making it ideal for efficient extraction of macromolecules.

• No exclusion of large molecules
• Good for desalting proteins
• Successful separation of proteins, peptides, or nucleotides

Bond Elut EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15,000 MW), which are typically excluded from standard porosity silica phases. Typical matrices include aqueous samples and biological fluids.
