Las columnas Supelcosil® ABZ+ Plus ofrecen elevada desactivación y selectividad única. Las partículas de sílice desactivadas con una distribución granulométrica muy estrecha aseguran una elevada eficiencia a baja contrapresión. Después de las reacciones de enlace y "fijación de grupos residuales" ("endcapping"), la fase ABZ+ Plus protege de forma efectiva los grupos silanol que no han reaccionado con la sílice, impidiendo que interaccionen con la mayor parte de los analitos, y proporciona picos simétricos independientemente de la funcionalidad del analito. Esta fase también le permite usar tampones de menor fuerza iónica sin necesidad de añadir un modificador de amina.
Features and Benefits
• Elevada eficacia para analitos polares, no polares y con carga • Picos simétricos para los compuestos más reactivos • Selectividad extraordinaria para compuestos polares y con carga.

F2-isoprostanes are a family of prostaglandin F2-like compounds that are formed by free-radical-catalyzed peroxidation of arachidonic acid. Several F2-isoprostanes, but in particular 8-epi PGF(2alpha), are widely used as oxidative stress biomarkers. An analytical method based on liquid chromatography with negative
