Trace Impurity Identification using Q-TOF Mass Spectroscopy Authors: Dr. Osama Chahrour, Alan Thompson and Dr. John Malone Accurate Mass Spectrometry (MS) techniques are ideally suited to aid in the structural elucidation of trace impurities. A rapid approach used for the isolation and characterisation of trace impurities in drug substances and formulated drug products has been developed. The approach has been successfully employed for the
