Phenomenex Catalog International 2009 - (Page 25) Strata -X Polymeric (SPE) Sorbents ™ Strata-X: Extract Polar and Non-polar Compounds by Reversed Phase • Enhanced retention for polar and aromatic compounds • Strong pi-pi retention mechanism allows for aggressive organic wash (> 5 % organic) without breakthrough of analyte • Effectively retains hydrophobic contaminants • Allows for simultaneous screening of acidic, basic, and neutral compounds Reversed Phase Selectivity Without Limitations Standard reversed phase SPE sorbents such as C18 and C8 retain analytes strictly by hydrophobic interactions. The Strata-X reversed phase sorbent retains analytes by hydrophobic interaction and has H- and π-π bonding capabilities for enhanced retention of polar and aromatic analytes. The enhanced retention mechanism of Strata-X can be very powerful for applications that require simultaneous extraction of polar analytes (log P 2). The strong retention mechanisms of Strata-X allow for aggressive washing with organic solvents to remove impurities without breakthrough of analyte. Strata-X offers reversed phase selectivity without the limitations such as improper cleanup, breakthrough, pH considerations, and method development concerns.
