Oasis HLB 20 cc Vac Cartridge, 1 g Sorbent per Cartridge, 60 µm, 20/pk
Use the Oasis HLB 20 cc Vac Cartridge to easily collect larger samples for analysis. The lab equipment contains the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent that has been developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol. The Oasis HLB sorbent is also water wettable, and so, maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry. This means that you do not need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps before the loading of the sample. The product listed here offers 60 µm particle size, which is recommended for working with viscous samples.
These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
The Oasis HLB 20 cc Vac Cartridge is made using a specific ratio of two monomers, the hydrophilic N-vinylpyrrolidone and lipophilic divinylbenzene. Some key benefits are achieved using this combination. These include stability at pH extremes and in a wide range of solvents, as well as extraordinary retention of polar compounds. Additionally, you get a relative hydrophobic retention capacity that is three times higher than that of traditional silica-based SPE sorbents.
Due to the higher retention capacity of the Oasis HLB 6 cc Vac Cartridge, you can improve the recovery and overall reproducibility of your SPE method as more analytes are retained with less breakthrough.
