Bond Elut™ Focus solid phase extraction cartridges with enhanced polar recovery. Features a unique amide functionalised polar-enhanced sorbent technology that delivers outstanding retention for polar and non-polar analytes.

• Simple, universal method reduces method validation times
• 'Power Rinse' delivers cleaner extracts, improving sensitivity
• Hydrogen bond donor capability increases retention of basic analytes

Rigorous washes using 10 to 20% ACN and MeOH can be used to aggressively remove endogenous matrix interferences. For very polar analytes that are held by strictly polar interactions.
