Recommended applications: more polar compounds like pesticides and their polar degradation products, phenols, phenoxycarboxylic acids, nitroaromatics, pharmaceuticals. 2 MACHEREY-NAGEL Capacity Capacity PK Cat.

Recommended applications: aflatoxins, chloramphenicol, pesticides, steroids, vitamins. 3 MACHEREY-NAGEL Capacity Capacity PK Cat.
