SPE Disks and Cartridges
Waters Corp Sep-Pak Vac Cartridge, PS2, 3 cc, 200 mg Sorbent, 80 μm
The Sep-Pak PS2 Vac Cartridge is a solid phase extraction product utilizing a styrene-divinylbenzene copolymer. It is suitable for concentrating pesticides and herbicides from water samples.
- Styrene-divinylbenzene copolymer packed in a short body cartridge.
- Applications include concentration of pesticides and herbicides in water.
- Used in Japan pesticide methods #5, #6, and #9.
- AC2 connected in series with PS2 was adopted as the official method for the extraction of pesticides from water by JPMHW.
Waters Corp Sep-Pak Vac RC Cartridge, 20 cc, Weak Cation-Exchanger, 500 mg Sorbent, 37–55 μm
These Vac RC cartridges feature a silica-based, hydrophilic weak cation-exchanger with a large pore size (300Å). They are designed for extracting cationic analytes from aqueous and non-aqueous solutions, and their large pore size makes them suitable for isolating molecules such as cationic proteins. They can also extract steroids, pesticides, and herbicides. An integral 20 cc funnel-shaped reservoir allows convenient processing of larger sample volumes, compatible with robotic sample preparation equipment and vacuum manifolds.
