The present invention relates to a sorbent for extracting polar components from a sample where the sorbent comprises a cross-linked polymer comprising nitrogen containing cyclic compounds, for example 1-vinylimidazole and/or 4-vinylpyridine. The invention further relates to a method of producing said sorbent and the use of the sorbent.

Material for and method of extracting mycotoxins

The present invention relates to a mesoporous polymeric separation material comprising one or more functional groups bound to metal ions from Cu, Zn, Ag, or Pd. Methods of producing the material, as well as methods for its preparation, and use of said material in separation of pesticides from food or feed products is disclosed.

Porous polymeric separation material

A class of molecularly imprinted polymers that specifically recognizes and binds to TSNAs are useful, for example, in analysis and separation of TSNAs from biological fluids. Such polymers are also useful in methods of treating and manufacturing tobacco products and materials. Also disclosed are selectively adsorbent non-molecularly imprinted polymer of a non-acidic monomer and a cross-linker having polar functionality, one of which is hydrophilic, the other of which is hydrophobic, and the use of such polymers in the treatment of materials containing nicotine and nitrosamine.

Polymers selective for tobacco specific nitrosamines and methods of using the same

Porous beads are provided of a polymer of a non-acidic monomer and a cross-linker having polar functionality, one of which is hydrophilic, the other of which is hydrophobic, further comprising residues of polyvinyl alcohol. The beads may be molecularly imprinted or non-molecularly imprinted. The use of such beads in the removal of nitroso-containing compounds from material containing them is also disclosed. Also disclosed is a non-molecularly imprinted polymer which is selectively adsorbent for at least one tobacco specific nitrosamine in the presence of nicotine, said polymer being a polymerization product of a non-acidic monomer and a cross-linker having polar functionality, one of which is hydrophilic, the other of which is hydrophobic.

The present application relates to an affinity material useful in antibody purification.

Affinity material

The present invention relates to a polymer bead material that are characterised by having pore sizes that can be pre-determined and that can be obtained with a narrow distribution of such pore sizes created by use of sacrificial filler materials within the polymer material. The invention also discloses processes for production of the material as spherical or approximately spherical beads or resins with predefined sizes. Also, the invention relates to the preparation of molecularly imprinted polymer materials that are created by the said method. Further the invention relates to the use of said polymer materials for separation, detection, catalysis or entrapment of chemicals, metal ions, inorganic compounds, drags, peptides, proteins, DNA, natural and artificial polymers, natural or artificial compounds, food or pharma products, viruses, bacteria, cells and other entities.

Methods for making polymer beads

An embodiment of the present invention relates to a composite material including a hydrophobic porous organic polymer bead. An embodiment further relates to a method of obtaining the composite material as well as the use thereof.

Composite material

The present invention relates to molecularly imprinted polymers, methods for their preparation and use of said molecularly imprinted polymers in separation, chemical sensors, drug screening, catalysis and in regioselective and enantioselective synthesis.
