Strata-X Outperforms Oasis® HLB

We've studied 3 critically evaluated areas: Recovery, Loadability, and Reproducibility to determine the benefits of Strata-X over Oasis HLB.

X-CW, Weak Cation Mixed Mode Phase Detail

Sorbent Type	Polymer-based
Surface Area (sq. m/g)	800
pKa	~4.5
Target Analytes	Basic compounds, particularly strong bases

Compare All Phases

X-CW, Weak Cation Mixed Mode Phase Information

A weak cation-exchange functionalized polymeric sorbent that allows for complete retention of basic compounds with a pKa greater than 8, including quaternary amines, making 100% organic wash conditions possible. A 100% organic wash ensures that the maximum amount of interferences are removed from the target compound.
