C18W Solid Phase Extraction Column Plates

The B&M® C18W (Uncapped) is a silica gel-based, non-capped reversed-phase extraction column C18, where a higher number of silanolic functional groups on the surface provides additional polar interactions. Nonpolar compounds are extracted through hydrophobic interaction.

At the same time, the activity of the silanol groups provides a better retention capacity for some drug metabolites and major compounds compared to capped C18, so that the retention mechanism includes moderately nonpolar and polar secondary interactions.

The column retains most organic compounds with a wide range of selectivity, making it a versatile stationary phase for the extraction of polar and non-polar compounds.

This column is equivalent to Aglient Accu Bond C18, Bond elute C18 OH.
