Empty CHROMABOND® column (PP) for SPE, one PE-filter element is already inserted in the column.
The innovative cation exchanger offers:mixed-mode SPE phase with distinct cation exchange and RP properties excellent enrichment of basic analytesmodern support polymer with optimised pore structure and large specific surfacegood reproducibility, reliable and cost-efficient analysesmore aggressive washing procedures for matrix removal possiblecleaner samples and protection of analytical HPLC and GC instrumentationquantificationof analytes from heavily contaminated sampleslower limits of detection also for critical matrices... the perfect fit for basic analytes in comination with CHROMABOND® HR-X
Octadecyl modified silica phase for SPE, not endcappedBase material silica, pore size 60 Å, particle size 45 µm for C18, specific surface 500 m²/g, pH stability 2 to 8 octadecyl phases, not endcapped, carbon content 14 % possesses more free silanols (SiOH), which allow secondary interactions with polar groups of the analytes.Recommended applications: non-polar compounds, pesticides.
Special phase for drying organic samplesBasic material: Sodium sulfate.Recommended application: removal of traces of water from organic solutions.
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
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.
Magnesium silicate for SPEMatrix magnesium silicate (MgO to SiOH 15:85), high purity, particle size 150 to 250µm.Recommended application: organic tin compounds, aliphatic carboxylic acids, PCB, PAH.
