CHROMABOND® QuEChERS

Special silica phase for determination of pesticides in food samples

Features
- Base material silica, pore size 60 Å, particle size 45 μm, specific surface 500 m2/g, pH stability 2–8
- Primary and Secondary Amine functions (PSA), 5 % C
- Removes polar compounds (e.g., organic acids, pigments, sugars) from matrices like fruit or vegetables
- Similar phases: Supelclean PSA, Bond Elut PSA

Recommended application:
- special SPE phase for quick and cheap determination of pesticides in strongly matrix-contaminated samples by GC-MS and LC-MS (see application 303770 and application 305060)
- QuEChERS method = Quick Easy Cheap Effective Rugged Safe


QuEChERS method and pre-mixes

Within a few years after its development by Anastassiades et al. the QuEChERS method has gained a leading position for the determination of pesticide residues in food samples by GC-MS or LC-MS, allowing rapid and cheap clean-up of strongly matrix-contaminated samples.

For optimizing the extraction of pH-dependent compounds, for minimizing decomposition of sensitive substances, and for broadening the matrix spectrum, different modifications of the QuEChERS method have been elaborated.

In addition to the adsorbent CHROMABOND® Diamino MACHEREY-NAGEL offers a number of individually weighed and premixed extraction (buffered or non-buffered) and clean-up mixtures, specially composed for different sample matrices.

For extraction, the European standard EN 15662 recommends a citrate extraction mix (Mix I), while the AOAC standard 2007.1 uses an acetate extraction mix (Mix II). A non-buffered extraction mix is used in the original method (Mix XII).

For clean-up, the Diamino phase (PSA) removes, e.g., sugars and organic acids. Magnesium sulfate removes water, C18 ec removes nonpolar interferences such as fats and the Carbon phase removes pigments, sterols, and nonpolar interferences.
