The second step:

To purify the organic extracts, select the appropriate dispersive SPE kit depending on the method and matrix. An aliquot of the extract from the first step is added to a 2 mL or 15 mL centrifuge tube containing the QuEChERS components to remove interfering matrix components and to bind existing water

The BEKOlut® PSA kits (with 2 or 15 mL centrifuge tubes) are prefilled with PSA (primary secondary amine) to remove oligosaccharides and fatty acids, with magnesium sulphate to bind water and/or C18e to remove residual lipids and/or GCB (graphitized carbon black) to remove colour pigments and are therefore suitable for direct use

Do you use special mixtures? We already have a long list of special fillings; we are also happy to fill your quantity and the sorbents of your choice

The 15 mL centrifuge tubes of the dispersive SPE kits are provided with color-coded lids for reliable differentiation, the 2 mL centrifuge tubes are clearly marked with a special imprint
