Cambridge Isotope Laboratories

Cambridge Isotope Laboratories, Inc. (CIL) is the world’s leading producer of stable isotopes and stable isotope-labelled compounds.

With over 400 employees and laboratories in four countries, CIL specializes in the process of labelling biochemical and organic compounds with highly enriched, stable (non-radioactive) isotopes of carbon, hydrogen, nitrogen and oxygen for use in mass spectrometry (mass spec) or nuclear magnetic resonance (NMR).

Buchem BV is proud distributor for CIL products in the Benelux.

    Neonatal Standards

    CIL has been manufacturing amino acid and carnitine/acylcarnitine calibration standards for over 15 years. We offer both 10-vial sets or single vials of these products.

    NSK-A - Amino Acid Reference Standards

    This set contains 10 vials of a dry mixture of 12 isotopically labelled amino acids. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce the concentrations presented in the Standard Concentrations table.

    NSK-B - Free Carnitine and Acylcarnitine Reference Standards

    This set contains 10 vials of a dry mixture of eight isotopically labelled free carnitine and acylcarnitines. Accurate and complete reconstitution of the contents of one vial in 1 mL of high purity solvent will produce the concentrations presented in the Standard Concentrations table.

    NSK-A-TS and NSK-B-TS

    Tandem Mass Spectrometer (MS/MS) Tuning Standards, NSK-A-TS and NSK-B-TS, have been developed to complement quality assurance and quality control (QA/QC) procedures in the laboratory.

    NSK-S-CAH - Congenital Adrenal Hyperplasia (CAH) Reference Standards

    NSK-S-CAH Congenital Adrenal Hyperplasia (CAH) Reference Standards is designed as a calibrator for use in screening, diagnosis and monitoring procedures for metabolic disorders. When used as directed, NSK-S-CAH provides a solution containing steroids at defined concentrations. When combined with techniques such as tandem mass spectrometry (MS/MS), LC/MS, GC/MS, etc., the solution may be used as a calibrator to measure concentrations of steroids in plasma, blood spots, urine and other bodily fluids.

    Each vial (packaged as 1 to 10 vials per box) contains only a dry mixture of isotopically labelled steroids. Complete reconstitution in 1 mL of solvent will produce the concentrations presented in the Standards Concentrations table.
