NMR Solvents and Consumables

NMR Solvents and Consumables

CIL’s NMR solvents are the preferred solvents worldwide for academic, pharmaceutical, industrial and government researchers. Our chemists employ methods for solvent purification that improve upon our already high standards for chemical and isotopic purity. We have increased production capacity in our state-of-the-art facilities to meet our customers’ growing demands.

 

CIL has two dedicated NMR for in-process testing, as well as three additional NMR spectrometers in our Quality Control department. Our solvents are packaged under an argon or a nitrogen atmosphere to ensure the purity is not compromised during packaging. CIL uses amber ampoules and bottles which protect those solvents that exhibit light sensitivity. Every bottle or box of ampoules is clearly marked with a lot number for proper identification.

 

Every lot of CIL solvent is routinely tested for both chemical and isotopic purity prior to release to inventory. Prior to use and after each dispensation, each lot is checked for chemical purity and moisture. 1H NMR data is acquired for each solvent we manufacture and some solvents are tested for purity by GC/MS for contaminants which would not be observed by 1H NMR. CIL’s Quality Control department tests for water content in our solvents use the Karl-Fisher titration method and our deuterated choloroform is tested for the presence of phosgene. All of our chlorinated solvents are tested for acidity.

 

CIL is also pleased to offer many NMR reference standards in 5 mm size as well as in 3 mm and 10 mm sizes. CIL has been manufacturing many of these standards for over 20 years, and we can provide custom standards as well as custom fill heights as may be necessary. Finally, for your added convenience we offer both Norell® and Wilmad-LabGlass NMR tubes.

qNMR Standards

qNMR Standards

Quantitative 1H-NMR (qNMR) continues to be utilized with much success in the pharmaceutical, chemical and food industries and in many facets of academic research. Regardless of the application, all qNMR methods require a calibration signal whose integrated signal intensity originates or is traceable to a known number of protons. Calibration for qNMR is made using either internal or external referencing methods. External methods rely on the use of a standard solution packaged in a defined NMR tube or capillary to obtain an integral that can be used for sample quantification, whereas internal methods rely on the use of a known amount of standard that is co-dissolved in the sample itself.
