SPE Disks and Cartridges
Waters Corp Vac Cartridge, WAX, 500 mg, 60 μm
This mixed-mode, Weak Anion-eXchange, reversed-phase, water-wettable polymer is designed for sample analysis in various matrices (drinking water, groundwater, surface water, wastewater, soil, food). It enables environmental testing laboratories to perform low-level quantification of per- and polyfluoroalkyl substances (PFAS) in environmental samples, ensuring extraction and concentration without cross-contamination via comprehensive quality control pre-screening for 32 PFAS, reducing false positive results.
- Delivers unmatched purity, consistency, and quality for sample analysis.
- Designed specifically for environmental testing laboratories.
- Enables PFAS extraction and concentration without cross-contamination.
- Comprehensive quality control pre-screening test for 32 PFAS.
- Provides assurance in results through application-specific quality control testing.
Waters Corp Sep-Pak Alumina A 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp SPE Cartridge, 1 cc, 60 mg Sorbent, 30 μm, WAX
The SPE 1 cc Cartridge is designed for oligonucleotide bioanalysis and contains 60 mg of OligoWorks SPE WAX Sorbent per cartridge. The sorbent is a polymeric reversed-phase, weak anion exchange mixed-mode sorbent, which is oligonucleotide tested and batch-selected for optimal oligonucleotide recovery.
