Waters Corporation Sep-Pak Vac Cartridge, Alumina N, 5 g, 20 cc
Sep-Pak Alumina N Vac cartridges provide a highly active, neutral alumina sorbent with an extremely polar surface for analyte retention, acting as a Lewis acid. This normal phase sorbent offers greater stability than silica under high pH, making it ideal for applications like synthetic crude oil fractionation. These syringe-barrel cartridges are designed for efficient use with vacuum manifolds and automated Solid Phase Extraction (SPE) instruments.
- Highly active alumina with neutral surface chemistry.
- Extremely polar surface for analyte retention, acting as a Lewis acid.
- Normal phase sorbent; more stable than silica under high pH.
- Ideal for synthetic crude oil fractionation and other organic compound analyses.
- Syringe-barrel design for vacuum manifolds and automated SPE instruments.
- Quality controlled for repeatable separations and reduced background interferences.
Waters Corp Oasis Vac Cartridge, 3 cc, 400 mg Sorbent, 60 μm
The Oasis HLB Vac Cartridge is a multi-purpose, reversed-phase sorbent with a water-wettable copolymer stable from pH 0–14. It provides analyte specificity and increased sensitivity for Solid Phase Extraction (SPE), allowing analytes to be retained even when loaded directly in an aqueous sample solution, offering excellent recoveries and higher retention.
- Water-wettable copolymer stable from pH 0–14.
- Eliminates condition and equilibration steps, reducing overall sample preparation time.
- Reduces solvent consumption by up to 70% and sample preparation time by 40%.
- Offers high recoveries and retention for diverse compounds.
- Hydrophilic-lipophilic balance retains both polar and reversed-phase compounds.
- Higher retention capacity improves recovery and reproducibility of SPE methods.
Waters Corp Waters Oasis MAX Flangeless Vac Cartridge, 1 cc, 10 mg, 30 μm
The 1 cc flangeless Oasis MAX cartridges contain a novel, mixed-mode polymeric sorbent optimized for higher selectivity and sensitivity in extracting acidic compounds with anion-exchange groups.
- Water wettable, maintaining higher retention and excellent recoveries even if the sorbent runs dry, eliminating the need to take extraordinary steps to keep sorbent beds from drying out before sample loading.
- Flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
