Encompass_Preferred

These Vac cartridges offer active alumina with neutral surface chemistry. The aluminum oxide surface provides polar analyte retention and Lewis acid properties. This normal phase sorbent is more stable than unfunctionalized silica under high pH, ideal for synthetic crude oil fractionation. Quality controlled for reproducible separations, they provide superior performance for ultra-low level analyte detection, reducing background interferences. Syringe-barrel-type for vacuum manifolds and automated SPE instruments.

  • Highly active alumina, neutral surface.
  • Polar analyte retention, Lewis acid properties.
  • More stable than silica in high pH.
  • Suitable for synthetic crude oil fractionation.
  • Quality controlled separations.
  • Superior for ultra-low analyte detection; reduces interferences.
  • Syringe-barrel-type for vacuum manifolds/automated SPE.
