Mixed-mode selectivity, generic methodology
and efficient extraction
EVOLUTE CX mixed-mode resin-based SPE sorbent extracts a wide range of basic analytes from biological fluids and other aqueous matrices using a generic procedure which minimizes method development time. EVOLUTE CX removes matrix components such as proteins, salts, non-ionizable interferences and phospholipids, delivering cleaner extracts with reproducible recoveries for accurate quantitation.
EVOLUTE CX sample preparation products are available in a range of standard configurations.
High selectivity provides ultra-clean extracts
The mixed-mode sorbent chemistry and optimized pore size minimizes retention of high molecular weight matrix components present in the biological fluid samples (Figure 1). The interferences including proteins, salts, non-ionizable molecules and phospholipids are removed during the interference elution step, thereby ensuring extremely clean extracts for LC-MS/MS analysis (Figures 2a and 2b).
Figure 1 The combination of optimized pore structure and additional interference elution steps using mixed-mode sorbent chemistry guarantees extremely clean extracts.

Simple, fast method development
EVOLUTE CX uses a single generic methodology suitable for a wide range of basic drugs.
High analyte recoveries
EVOLUTE CX has a water-wettable surface to promote robust, reliable sample preparation. The combination of robust polymer chemistry, uniform coverage of sulfonic acid (SO3-) groups and optimum exchange capacity provide greater than 85% recovery for a wide range of basic drugs.
Excellent flow characteristics
Narrow particle size distribution provides consistent flow characteristics for a variety of sample matrices. Optimized packing techniques eliminate channelling, which can lead to analyte breakthrough.
The surface characteristics of each batch of EVOLUTE CX are quality controlled and tested to ensure consistency.
