Bond Elut™ C18 is a hydrophobic silica sorbent. C18 is commonly used for non-polar compounds. Bond Elut™ C18 is endcapped to reduce interactions with silanol groups.

• Extremely retentive for nonpolar compounds
• Effective for desalting aqueous mixtures
• The most hydrophobic, bonded silica sorbent

Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent available in the Bond Elut™ range. It is the most popular SPE sorbent because of its extreme retentive nature for nonpolar compounds.

C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices before ion exchange, as salts pass through the sorbent unretained.
