Chemical Purity

CIL’s products all pass rigorous quality control tests prior to being released to inventory for use by our customers. The chemical purity (CP) of our stable isotope compounds is assured by one, or a combination, of the following techniques: nuclear magnetic resonance (NMR), gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and melting point analyses.
