Description
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:
If required, add ceramic homogenising beads for better mixing.
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

Diol modified silica phase for SPEBase material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, diol phase, carbon content 5.5%, polar properties similar to SiOH.Recommended application: antibiotics, prostaglandins.
Unmodified silica phase for SPEUnmodified, weakly acidic silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, very polar, adsorbs humidity from air, for this reason it should be kept well closed and if necessary dried before use due to its high affinity for polar compounds it should not be conditioned with polar (e.g. methanol) or water-containing solvents.Recommended applications: aflatoxins, chloramphenicol, pesticides, steroids, vitamins.
