Dispersive SPRE Clean-up

Teknokroma QuEChERS Kits – Efficient Pesticide Residue Extraction and Clean-up

The name QuEChERS stands for Quick, Easy, Cheap, Effective, Rugged, and Safe, a highly effective method for determining pesticide residues in fruits, vegetables, and other food products.

The QuEChERS method is a dispersive solid-phase extraction (dSPE) technique, involving two stages: an initial extraction phase, followed by a clean-up phase to purify the extract.

 

2️⃣Phase 2: Clean-up and Purification
2 ml and 15 ml centrifuge tubes are used in this stage.
✔ The extract from the previous phase is purified using dispersive solid-phase extraction (dSPE), removing residual water and matrix interferences that could affect the analysis.
✔ Various salts and sorbents are used depending on the recommended method:

  • MgSO₄ (removes residual water)
  • Primary/Secondary Amine (PSA) (removes organic acids and sugars)
  • C18 (removes lipids and non-polar interferences)
  • Graphitized Carbon Black (GCB) (removes pigments like chlorophyll and carotenoids)
    ✔ After purification, the sample is centrifuged, evaporated, and reconstituted in the appropriate solvent for subsequent analysis.

🔹 Teknokroma QuEChERS Kits – Compatible with Official Methods
✔ Fully compatible with standard methods: EN15662, AOAC 2007.01, and Mini-multiresidue.
✔ Available with pre-measured salts/adsorbents in individual sachets for easy sample preparation (P/N+K).
