Description

Recommended for quick and cheap determination of pesticides by GC-MS and LC-MS. Macherey-Nagel™ CHROMABOND™ QuEChERS Citrate Extraction Mix, EN 15662 is a pre-weighed, pre-mixed buffered SPE phase for pesticide residue analysis in strongly matrix-contaminated samples, e.g. fruits and vegetables.

Mix I is an individually weighed and premixed buffered extraction used with the QuEChERS method. It is specially composed to satisfy the European standard EN 15662, which recommends a citrate extraction mix to remove polar compounds (e.g., organic acids, pigments, sugars) from matrices like fruits or vegetables. This phase can be used with foods with higher fat or chlorophyll/carotenoid contents.

The QuEChERS method (Quick, Easy, Cheap, Effective, Rugged, Safe) is the leading method for the determination of pesticide residues in food samples by GC-MS or LC-MS. It allowa rapid and cheap clean-up of strongly matrix-contaminated samples. These QuEChERS extraction mixes provide many advantages to lab productivity compared to classical clean-up methods:

  • Pre-weighted packages are easy to handle and save time and money
  • No need for glassware—supplied in individual 15mL centrifuge tubes with caps
  • Low consumption of solvents and no need for chlorinated solvents
  • Broad range of pesticides can be detected
  • Rugged method with high and safe recovery rates
  • Similar phases: Supelclean PSA, Bond Elut PSA
