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
Special silica phase for SPE enrichment of drugs from urine or plasmaBase material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, special bifunctional modification - C8/SA (strong cation exchanger - benzenesulphonic acid).Recommended application: enrichment of acidic, neutral and basic drugs from urine or plasma.
Polar modified polystyrene-divinylbenzene copolymer with a weak anion exchangerSpecific surface 650 to 700 m²/g, particle size 80µm, pore size 50 Å, pH stability 1 to 14. Due to bifunctional modification much more hydrophilic than conventional polystyrene-divinylbenzene polymers and thus easily wettable with water.Recommended applications: polar herbicides / pesticides from water (acidic, neutral, basic), polar phenols from water, polyaromatic compounds, polychlorinated biphenyls, drug analysis from urine, blood, serum, plasma pharmaceuticals / active ingredients from tablets, creams.Due to the bifunctional modification CHROMABOND® Easy is considerably more hydrophilic than conventional polystyrene-divinylbenzene polymers and thus easily wettable with water. The Easy effect: Aqueous samples can be loaded directly without preconditioning! This means that little or even no conditioning is needed, in contrast to standard SPE materials, where recovery rates normally decrease, in the worst case down to zero! Depending on the separation task conditioning may be required and is recommended for method development. A positive side effect of the excellent wettability: there is no decrease of recovery rates, if the cartridge runs dry, therefore automation is easier or, in some cases compared to silica materials, only feasible with CHROMABOND® Easy, because a permanent vacuum can be used without supervision.Further advantages of using a polymeric material:high surface, this means very high binding capacity (2 - 5 times higher than silica-based adsorbents)less adsorbent is needed in the cartridge (without losing sensitivity or recovery)faster analysis, because the height of the adsorbent bed can be reducedacidic or basic solvents (e. g. TFA) do not destroy the phase, or lead to unintended side productsBecause of the polar modification the material is suitable for a broad range of compounds (acidic, neutral, basic, polar and nonpolar substances). Highly reproducible recovery rates can be obtained, even if the cartridge runs dry (especially advantageous when using 96-well plates, where stopcocks are not available!)
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.
