A gas chromatograph\/combustion\/isotope ratio mass spectrometer (GC\/C\/IRMS) was modified to include a headspace extraction system followed by a cryogenic trap. Extracting headspace from a 160\u2009mL vial with 80\u2009mL of aqueous solution and 40\u2009g of NaCl for 8\u201312\u2009min resulted in accurate and reproducible\n                    <jats:italic>\u03b4<\/jats:italic>\n                    <jats:sup>13<\/jats:sup>\n                    C values for trichloroethene (TCE) and cis\u20101,2\u2010dichloroethene (cDCE) at concentrations of 50\u201375\u2009\u03bcg\/L. Based on these results a conservative lower limit of quantitation of 38\u2009\u03bcg\/L can be calculated for these compounds. For more volatile compounds such as tetrachloroethene (PCE) and vinyl chloride (VC), field data analyzed using this method indicate a lower limit of quantitation in the tens of \u03bcg \/L range.
