Clean Screen® DAU SPE Cartridges (Standard)

This sorbent is composed of a silica backbone with two types of functional chains attached - an ion exchanger or polar chain and a hydrophobic carbon chain. Our copolymeric phases are produced in a way to allow for equal parts of each functional group to attach to the silica backbone. This copolymerization technique yields reproducible bonded phases and unique copolymeric chemistries which allow the controlled use of mixed mode separation mechanisms. This type of dual chemistry is beneficial especially when one is looking for both a neutral & charged compound. This is common when a neutral parent drug metabolizes & becomes a charged compound.

Clean-Screen® DAU Bulk Sorbent

• Chemical Phase = BCX + C8
• Organic Loading = 12.4%
• Average Pore Size = 60Å
• Cation Exchange = 0.077 meq/g
• Surface Area = 500 m²/g
• Pore Volume = 0.77 cm³/g

Condition Column: Proper conditioning of the SPE column prior to sample application will result in accurate recovery, reduced interference and particulate removal. Conditioning is performed by adding methanol, followed by DI water and finally sample buffer.
