SKU: 186002493 Oasis WAX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 30 µm, 30/pk
The 6 cc Oasis WAX cartridges contain the Oasis WAX sorbent, which is a polymeric reversed-phase, weak anion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong acidic compounds. Since the Oasis WAX 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.
How much sample can the Oasis WAX 6 cc Vac Cartridge hold? The Oasis WAX 6 cc Vac Cartridge can hold up to 150 mg of sorbent per cartridge.
What is the pore size of the filtration membrane in the Oasis WAX 6 cc Vac Cartridge? The filtration membrane in the Oasis WAX 6 cc Vac Cartridge has a pore size of 30 µm.
Can the Oasis WAX 6 cc Vac Cartridge be used for both aqueous and organic samples? Yes, the Oasis WAX 6 cc Vac Cartridge is compatible with both aqueous and organic samples.
How should the Oasis WAX 6 cc Vac Cartridge be stored when not in use? The Oasis WAX 6 cc Vac Cartridge should be stored in a cool, dry place away from direct sunlight to maintain its effectiveness.
What is the recommended flow rate for using the Oasis WAX 6 cc Vac Cartridge? The recommended flow rate for using the Oasis WAX 6 cc Vac Cartridge is 1-5 mL/min.
What Is Reversed-Phase SPE?
In reversed-phase SPE, analytes are separated based on their polarity. The stationary phase of a reversed-phase cartridge is derivatized with hydrocarbon chains, which retain compounds of mid to low polarity because of the hydrophobic effect. The analyte can then be eluted by washing the cartridge with a non-polar solvent, which will disrupt the interaction of the analyte and stationary phase.
Commonly, a stationary phase of silicon with carbon chains is used. When relying on mainly non-polar and hydrophobic interactions, only non-polar or very weak polar compounds adsorb to the surface.
What Is Ion-Exchange SPE?
In this version of SPE, sorbents separate analytes based on electrostatic interactions between the analyte of interest and the positively or negatively charged groups on the stationary phase. Ion exchange occurs when both the stationary phase and sample are at a pH where both are charged.
