CIL's NMR solvents are the preferred solvents worldwide for academic, pharmaceutical, industrial and government researchers.
CIL has two dedicated NMR spectrometers for in-process testing, as well as three additional NMR spectrometers in its Quality Control department. Every lot of CIL solvent is routinely tested for both chemical and isotopic purity prior to release to inventory. 1H-NMR data is acquired for each solvent produced, and some solvents are tested for purity by GC/MS for contaminants that wold be observed by 1H-NMR.
CIL's Quality Control Department test for water content in solvents using the Karl Fischer titration method, and deuterated choloform is tested for presence of phosgene. All chlorinated solvents are tested for acidity. CIL's solvents are packaged under an argon or nitrogen atmosphere to ensure the purity is not compromised during packaging. CIL uses amber ampoules and bottles to protect photosensitive solvents from degradation.
