QuikPrep® SpinColumns™ for reverse phase chromatography are packed with a stationary non-polar phase. Available matrixes include C4, C8, C18 and TARGA C18. Reverse phase chromatography uses a column packed with a stationary non-polar phase, and a polar mobile phase is passed through the column. Molecules with similar polarities attract one another causing the most polar compounds to elute first as the non-polar compounds are held by the non-polar matrix These non-polar compounds can then be released through the addition of an elution buffer.

• C18, C8, C6 = Reverse phase bonding materials of different alkyl chain lengths
• Targa C18 = Monofunctional C18 phase with a unique polar and bulky end-capping
