3M™ Empore™ SDB-XC 90 mm Disk
SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction. SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.

Mobile-Phase Cleanup Using Solid-Phase Extraction Disks
In this comprehensive application note from 3M the authors describe a fast, simple procedure for purifying HPLC mobile phase using solid-phase extraction disks during the filtration step for mobile-phase preparation. The procedure tested was found to remove more than 95% of contaminants, and has been suggested as an effective and suitable solution for various gradient HPLC methods.
