Normal phases
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).

Product overview
Reversed-phase
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 phases
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.

Special phases
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.
