Waters Corp Oasis HLB 35 cc Vac Cartridge, 6 g Sorbent per Cartridge, 60 µm, 10/pk
The 35 cc Oasis HLB cartridges contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol. Since the Oasis HLB sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The 60 µm particle size is recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corporation Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 46 mg Sorbent, 40 μm, 50 pk
These cartridges feature a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. They are designed for the extraction of anionic analytes from various solutions, especially where chloride interference is a concern.
- Silica-based, hydrophilic, strong anion-exchanger with 300Å pore size and carbonate counter-ion.
- Extracts anionic analytes from aqueous/non-aqueous solutions; avoids chloride interference.
- Light-style format with reduced internal diameter; enables minimal volume elution.
- Improves recoveries and reduces solvent consumption for limited samples.
- Ideal for isolating anionic proteins, acidic pigments, phenolic compounds, and inorganic anions.
- Manufactured in ISO 13485/9002-registered facility, compliant with cGMP for Class 1 Medical Devices.
