Geochemistry and Metals Separation

TrisKem’s expertise in separation chemistry and its wide range of resins with different selectivities provides a number of opportunities to solve analytical problems through sample preparation.


With our broad products' offer and our long experience, TrisKem can help you meet lower detection limits with less uncertainty.


Frequently the problems encountered are centred on removing matrix interfering with the instrumental measurement.

ICP-MS is an example. Isobaric interferences have often to be removed in order to allow accurate determination of your analytes.


Selectivity for the analyte of interest is important in these cases. Extraction chromatography is widely used in various analytical applications, including the determination of Sr isotope ratios, in geochronology and dating (e.g. U/Pb, Nd/Sm,...), and the determination of Pb and Be in difficult matrices.


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
