Reagents for environmental monitoring, bioassay, geochemistry, radiopharmacy and decommissioning


TrisKem International is an ISO9000 certified company producing and developing extraction chromatographic resins.

Extraction Chromatographic Resins combine the selectivity of liquid-liquid extraction and the speed and ease of use of chromatography thus finding applications in a variety of domains.

TrisKem’s Extraction Chromatographic Resins have a high selectivity. The methods using them are shorter, demand less hands-on time, reduce and even sometimes avoid the use of toxic and dangerous reagents.

The resins are comprised of microspheric beads with a very high surface impregnated with an organic extractant. The large surface of the beads and the high content of extractant allow reducing the size of the columns, and therefore also the amount of reagents used – resulting in the generation of less waste.

Extraction Chromatographic Resins can be prepared using a wide choice of different extractants, and thus selectivities:


  • Liquid anion exchangers
  • Liquid cation exchangers
  • Solvating and chelating extractants
  • Macrocycles (e.g. crown ethers)
  • Ionic liquids

Extraction Chromatographic columns, cartridges and discs are simple to handle and can easily be used in vacuum based systems or in automated separation setups e.g. for the separation of high active samples in glove boxes or hot cells, as for example needed for the preparation of radionuclides for nuclear medicine.


Overall TrisKems product range is comprised of:
