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 tubeMix B, C, D and E are pre-weighed into a 15 ml tube

CHROMABOND® HR-X

Spherical, hydrophobic polystyrene-divinylbenzene resin for SPEHydrophobic polystyrene-divinylbenzene copolymer pH stability 1 to14. High-purity material with highest reproducibility and lowest blank values due to a novel manufacturing process, spherical particles 85mm; pore size 55 to 60Å. Very high surface 1000m²/g; capacity 390mg/g (caffeine in water). Excellent recovery rates especially for the enrichment of pharmaceuticals/active ingredients due to the spherical structure of the particles, very homogeneous surface, and optimised pore structure.Recommended applications: pharmaceuticals/active ingredients from tablets, creams and water/waste water, drugs and pharmaceuticals from urine, blood, serum and plasma trace analysis of pesticides.Cartridges in further sizes and phases of the HR-X poduct range available on request.
