SPE Disks and Cartridges
Waters Corp Waters Oasis MCX Vac Cartridge, 6 cc, 150 mg Sorbent, 30 μm
The 6 cc cartridges contain a novel, mixed-mode polymeric sorbent optimized for higher selectivity and sensitivity in extracting basic compounds with cation-exchange groups. This sorbent is water wettable, maintaining higher retention and excellent recoveries even if the sorbent runs dry, eliminating the need to prevent sorbent beds from drying out before sample loading.
- Novel, mixed-mode polymeric sorbent
- Optimized for higher selectivity and sensitivity for extracting basic compounds
- Contains cation-exchange groups
- Water wettable, maintaining retention and recoveries even if sorbent runs dry
- Eliminates the need to prevent sorbent beds from drying out during critical steps prior to sample loading
Waters Corporation Solid Phase Extraction Vac Cartridge, Oasis MCX, 3 cc, 60 mg, 60 μm
Oasis MCX 3 cc Vac Cartridge features a novel, mixed-mode polymeric sorbent for high selectivity and sensitivity in basic compound extraction. It is water wettable, ensuring consistent recoveries even if it runs dry. Designed for viscous samples (60 μm particle size), it is compatible with vacuum manifolds and automated SPE. Offers pH stability from 0 to 14 and higher binding capacity than silica-based sorbents, facilitating method development.
- Optimized for high selectivity & sensitivity in basic compound extraction, water wettable for consistent retention & recovery when dry.
- 60 μm particle size suitable for viscous samples; compatible with vacuum manifolds & automated SPE.
- Novel mixed-mode polymeric sorbent provides pH stability from 0 to 14 & greater binding capacity than silica-based SPE, preventing breakthrough/recovery loss.
Waters Corp Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Carbonate Plus Light cartridges contain a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. These cartridges are used for extraction of anionic analytes in aqueous and non-aqueous solutions when the chloride counter-ion in the standard Sep-Pak Accell Plus QMA cartridges interferes with the analysis. These Light-style cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
