Overview
The WondaPak QuEChERS Series is a standardized, high-efficiency dispersive solid-phase extraction (d-SPE) cleanup kit engineered for rapid, reproducible sample preparation in multi-residue pesticide and contaminant analysis. Based on the internationally validated QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) methodology, these kits leverage partitioning and selective adsorption principles to separate target analytes—such as pesticides, mycotoxins, veterinary drugs, and environmental contaminants—from complex biological and food matrices. The core mechanism involves salting-out-assisted liquid–liquid partitioning followed by d-SPE using functionalized sorbents packed into centrifuge tubes. This eliminates the need for traditional cartridge-based solid-phase extraction (SPE), significantly reducing procedural steps, solvent consumption, and analyst handling time while maintaining analytical robustness required for regulatory compliance.
Key Features
- Pre-weighed, factory-packed d-SPE sorbents in certified 2 mL and 15 mL centrifuge tubes—ensuring batch-to-batch consistency and minimizing weighing errors.
- Primary formulation includes anhydrous magnesium sulfate (MgSO₄) for water removal and phase separation, plus primary secondary amine (PSA) for effective removal of organic acids, sugars, fatty acids, and polar pigments.
- Modular sorbent options: C18 for non-polar lipid interference reduction; graphitized carbon black (GCB) for chlorophyll, carotenoid, and other planar pigment removal—enabling matrix-specific method optimization.
- No SPE manifold, glassware, or vacuum systems required—only a standard benchtop centrifuge and calibrated pipettes are needed for full workflow execution.
- Reduced solvent usage: up to 9× less organic solvent compared to conventional cartridge SPE, lowering operational costs, waste disposal burden, and exposure risk.
- Chlorine-free chemistry: avoids chlorinated solvents (e.g., chloroform, DCM), aligning with green analytical chemistry principles and institutional EHS policies.
Sample Compatibility & Compliance
The WondaPak QuEChERS Series is validated for use with a broad spectrum of agricultural, environmental, and food safety samples—including fruits, vegetables, cereals, meat, dairy, soil, and water extracts. It supports both AOAC Official Method 2007.01 and EN 15662:2018 protocols, making it suitable for laboratories operating under ISO/IEC 17025 accreditation requirements. All lots undergo rigorous QC testing for residual metal content, moisture, and adsorption capacity. Kits are supplied with CoA (Certificate of Analysis) and are compatible with GLP- and GMP-regulated environments where traceability, lot-level documentation, and audit-ready records are mandatory.
Software & Data Management
While the WondaPak QuEChERS kits themselves are consumable hardware, they integrate seamlessly into modern laboratory information management systems (LIMS) and electronic lab notebooks (ELN). Each kit batch is assigned a unique serial number traceable to manufacturing date, raw material certifications, and QC test reports—supporting 21 CFR Part 11-compliant audit trails when logged via validated LIMS platforms. Method templates for QuEChERS workflows—including centrifugation speed/time parameters, solvent volumes, and recovery spike levels—are readily importable into chromatography data systems (CDS) such as Thermo Chromeleon, Agilent OpenLab, or Waters Empower.
Applications
- Multi-residue pesticide screening in fruit and vegetable commodities per EU MRL regulations.
- Analysis of veterinary drug residues (e.g., sulfonamides, tetracyclines, fluoroquinolones) in animal tissues and milk.
- Quantification of mycotoxins (aflatoxins, ochratoxin A, deoxynivalenol) in cereal grains and feedstuffs.
- Environmental monitoring of persistent organic pollutants (POPs) in sediment and biota samples.
- Method development support for LC-MS/MS and GC-MS/MS workflows requiring low-background, high-recovery cleanup prior to instrumental analysis.
FAQ
What is the shelf life of unopened WondaPak QuEChERS kits?
Unopened kits retain full performance for 24 months when stored at room temperature (15–25 °C) in original sealed packaging.
Can I customize the sorbent composition for a specific matrix?
Yes—custom blends (e.g., PSA/C18/GCB ratios, MgSO₄ loading adjustments) are available under OEM agreements for high-volume users and contract testing laboratories.
Are these kits compatible with automated liquid handlers?
All 2 mL formats are designed for compatibility with robotic platforms equipped with standard tube racks and positive-displacement pipetting modules.
Do you provide method validation support?
Comprehensive application notes, spike recovery data across 300+ analytes, and AOAC/EN-compliant validation templates are provided upon request.
Is technical support available for troubleshooting matrix effects?
Yes—our application scientists offer remote method optimization assistance, including LC-MS/MS parameter alignment and d-SPE sorbent selection guidance based on your sample type and instrumentation.
