title: Clearing the undergrowth: detection and quantification of low level impurities using19F NMR.
abstract: A new method for the analysis of low level impurities in sparsely fluorinated species allows measurement of clean high dynamic range19F spectra, fully decoupled and free of interfering signals from13C isotopomers.
