EVOLUTE
ADVANCED POLYMERIC SORBENTS FOR OPTIMIZED SAMPLE PREP
EVOLUTE ®
Sample Preparation Products
EVOLUTE ® Sample Preparation Products are
advanced water-wettable polymer-based sorbents.
Developed specifically for analyte quantification by
LC-MS/MS, EVOLUTE products provide a highly
effective solution to the problems of ion
suppression and matrix effects from dirty extracts.
These high performance products allow scientists
to use generic methodologies to reduce method
development time while producing clean extracts
for a wide range of compounds.
Features and Advantages
• 40Å pore size and narrow pore size distribution provides cleaner extracts and reduced matrix effects
• Pore size also provides for improved signal to noise in LC-MS for lower detection levels
• Generic methodology means method development is fast and simple
• High quality leads to reproducible recoveries for a wide range of analytes
The EVOLUTE Family of sorbents has a uniquely modified surface structure that is water-wettable to promote
robust, reliable sample preparation. They also have an optimized pore structure that minimizes the retention
of high molecular weight endogenous materials present in complex sample matrices. The result is cleaner
extracts, compared to other leading polymer based SPE products.
Generic methods for high analyte recoveries
EVOLUTE ABN has a balanced combination of polar (hydrophilic) and non-polar (hydrophobic) interactions,
which, combined with simple generic methodology, allows simultaneous extraction of acidic, basic and neutral
analytes of wide ranging polarity.
EVOLUTE CX is a mixed-mode sorbent combining a water-wettable surface with uniform coverage of sulfonic
acid (SO 3
- ) groups with optimum exchange capacity. Generic methodology is available to provide greater than
85% recovery for a wide range of basic analytes from biological fluids and other aqueous matrices.
Excellent flow characteristics
EVOLUTE sorbents have a narrow particle size distribution providing consistent flow characteristics for a variety
of sample matrices, and resulting in reliable performance during automated sample processing. Optimized packing
techniques eliminate channeling, which can lead to analyte breakthrough.
EVOLUTE 30 µm sorbents are available in small volume columns and 96-well plates optimized for bioanalytical
sample preparation.
EVOLUTE 50 µm sorbents are optimized for processing larger volume or higher viscosity samples in environmental,
food safety, clinical, forensic and doping control applications.
