Clinical

As the use of advanced techniques such as mass spectrometry continues to increase in the field of Clinical analyis we are pleased to offer many isotopically labelled compounds for use as internal standards.
This range includes Catecholamines, Biogenic amines, Immunosuppresants, Thiopurines and Xanthines including Caffiene and metabolites. Please also see our other subcategories for stable isotopes of Carnitines, Thyroxines and Toxicology reference materials.
Please don’t hesitate to contact us if you are unable to find the stable isotope that you need and we'll be delighted to check on its availability.
