Extraction kits Copure® QuEChERS

Extraction and clean-up mixtures for sample preparation in the pesticide analysis of vegetable foodstuffs according to EN 15662 using GC/MS or LC/MS after acetonitrile extraction and purification using the dispersive SPE-QuEChERS method.

The samples are first extracted with Mix A. Purification is done with one of the following mixtures:
  • Mix B (Clean-up mixture for fruits and vegetables with low fat content, e.g. apples, strawberries)
  • Mix C (Clean-up mixture for fruits and vegetables with high fat content, containing oil/wax, e.g. avocados)
  • Mix D (Clean-up mixture for moderately chlorophyll/carotenoid-containing fruits and vegetables, e.g. carrots, salad)
  • Mix E (Clean-up mixture for fruits and vegetables with high chlorophyll/carotenoid content, e.g. sweet peppers, spinach)

If required, add ceramic homogenising beads for better mixing.
  • Mix A contains a bag with the required amount of mixture and a 50 ml empty tube
  • Mix B, C, D and E are pre-weighed into a 15 ml tube
