Waters, 186000776, Oasis MCX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 30/pk

The 6 cc Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX 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.

Additional Information
Oasis MCX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 30/pk Achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups using the Oasis MCX 6 cc Vac Cartridge. The cartridges utilize the Oasis MCX, a novel, specially designed mixed-mode polymeric sorbent. The Oasis MCX sorbent is water wettable, which means it can maintain its capability for higher retention and excellent recoveries even if the sorbent runs dry. This means that 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 Oasis MCX also offers dual modes of retention on a single, clean, stable, high-surface-area, organic co-polymer that is stable from pH 0-14. The dual retention modes offered are ion exchange, and reversed-phase. The Oasis MCX 6 cc Vac Cartridge, with 60 µm particle size, is a crucial piece of lab equipment and recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments. You may want to explore the PFC Analysis Kit for use in conjunction with this product.

FAQ
When Should A Gradient Be Used? It is recommended to run a scouting gradient if the conditions for a successful separation are unknown in reversed-phase HPLC. This can be done using a linear increase in elution strength, ca 10-80% organic modifier during 30-50 min. Based on the results, either an appropriate mobile phase composition can be chosen for isocratic elution (small molecules < 1000 g/mol) or a suitable gradient for the separation of peptides or other larger molecules.

Gradient elution can also be chosen for separation of compounds that vary greatly in their polarity. As a general rule, if peaks can be detected during more than 25% of the scouting gradient, gradient elution will likely be the best choice for that separation problem. If peaks appear for less than 25% of the scouting gradient, isocratic elution should be preferred, as the selectivity is superior under isocratic conditions.
