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


TrisKem International is well known manufacturer of extraction chromatographic resins which are standard methods in environmental monitoring and bioassay analysis used by worldwide accredited laboratories. Our company equally provides resins to facilitate the analyses which accompany the decommissioning of nuclear installations.


The high selectivity of our resins not only allows the analysis of standard alpha and beta emitters (actinides, Sr-89/90, Ni-63, Tc-99,…) from high matrix samples including concrete, spent resin, but also the determination of so called difficult-to-measure (DTM) radionuclides such as Sn-121m/Sn-126, Zr-93,


We are constantly working on developing new methods according to your needs. Methods for the following radionuclides are currently under development: Se-79, Sb-125, Cs-135, Nb-93m/Nb-94, Ag-108m, Pd-107, … For more information please find here enclosed a flyer summarizing technical information about some of the resins used in the analysis of decommissioning samples.


Besides the resins used for analysis of decommissioning samples, TrisKem International also offers a range of PAN based resins used for the decontamination of radioactively contaminated waters and effluents.


Our R&D team is working on the development of new resins and methods in order to help you with your separation needs. Having a special separation need, willing to participate in a R&D project or looking for a partner to commercialize a new technology you have developed, please do not hesitate to contact us at contact@triskem.fr
