EVOLUTE® EXPRESS SPE columns and plates combine sorbent wettability with optimized SPE components, allowing better flow consistency and in many cases eliminating the need for SPE column conditioning; thus simplifying and reducing extraction processing. This poster compares the performance of various EVOLUTE EXPRESS column chemistries using 10-500 mg bed weights, in order to investigate whether sorbent conditioning and equilibration steps are truly required.

This method describes the extraction of quaternary amines, strongly basic amines and amines that are unstable at high pH levels, from biological fluids. The mechanism is mixedmode
hydrophobic and weak cation exchange, allowing acidic elution conditions.
