BEKOlut® filter discs made of polyethylene or glass fiber offer optimum filtration depending on sample viscosity and application - in various pore widths, thicknesses and diameters, suitable for 1, 3 and 6 mL columns.
BEKOlut® SPE empty polypropylene columns in 1, 3 and 6 mL are ideal for self-filling - with or without matching 10 µm frits.
BEKOlut® syringe filters are used for the filtration of particle-laden aqueous and organic solutions prior to the actual analysis.
Medium-polar and polar analytes from lipophilic sample extracts can be fractionated on normal phases such as silica gel and aminophase according to the polarity of the functional group(s).
Silica gels for reversed-phase SPE are hydrophobically modified and therefore non-polar. They are used when moderately polar to non-polar substances are to be extracted from aqueous solutions and biomatrices.
Ion exchange SPE is particularly suitable for selectively extracting charged analytes from aqueous samples. Cation and anion exchangers based on silica or polymers are available.
In addition to a variety of special applications, the extraction of mineral oil hydrocarbons with BEKOlut H53/OI ready-to-use glass columns and the SPE of acrylamide from water samples with a special activated carbon phase are of interest.
High-purity SPE columns for the MultiPrupose Sampler MPS from GERSTEL or ready-to-use SPE cartridges for the ASPEC from GILSON are available on request.
Undesirable mineral oil residues are found in numerous foods or food contact materials. The complexity of the analytes requires special sample preparation and analysis.
Select the extraction kit suitable for your desired method (EN 15662, AOAC 2007.01 or original 10/15 g sample). For sensitive analytes, such as pH-sensitive pesticides, the buffered salt kits are particularly suitable.
Depending on the method and matrix, select the appropriate dispersive SPE kit to purify an aliquot of the extract in a 2 mL or 15 mL centrifuge tube from interfering Martix components.
BEKOlut Easy'n fast QuEChERS cartridges are ideal for rapid sample preparation of plant-based foods with low fat and pigment content - perfect for fruit, vegetables and GC-MS/MS analysis.
