چکیده انگلیسی
A method using reversed-phase high performance liquid chromatography (HPLC) with UV detection has been developed and validated for the trace level (ng/mL) detection and quantitation of ethyl diazoacetate (EDA), a toxic impurity, in sample matrix. Method development included the evaluation of several analytical techniques including LC–MS and GC–MS, which in this case, proved to be unacceptable means of analysis. The chromatographic separation employed in this method utilizes a mobile phase system of acetonitrile and water with analysis carried out using UV detection at 250 nm. The final method showed excellent linearity, accuracy, repeatability, specificity and recovery when evaluated at the quantitation limit (QL) of 6 ng/mL.
