Sequential determination of chlorine and carbon isotopic composition in single microliter samples of chlorinated solvent

摘要

Chlorinated hydrocarbons, significant environmental pol- lutants, may be characterized by stable isotopic composi- tions of carbon and chlorine, previously published analytical methods needed separate preparations for carbon and chlorine and were not ideal for environmental studies because of low sensitivity and precision. This method quantitatively extracts both carbon and chlorine from a single aliquot of chlorinated solvent of a size practically applicable to natural systems.
