However, in field studies, hydrogen CSIA has been used only in non\u2010chlorinated volatile organic compound (VOC) investigations, due to low conversion yields into hydrogen gas and poor reproducibility. Therefore, it is important to develop hydrogen CSIA methodology for soil and subsurface contamination studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>\n                      A new analytical method for determining compound\u2010specific hydrogen stable isotope ratios is presented. The isotopic ratios were measured by gas chromatography\/isotope ratio mass spectrometry (GC\/IRMS) coupled with a chromium reduction system.

The precision of the new analytical method (better than \u00b17 \u2030) is better than that obtained from the offline method. The quantification limits of the headspace\u2010solid\u2010phase microextraction (SPME) are 400\u2009\u00b5g\/L and 200\u2009\u00b5g\/L for TCE and cis\u2010DCE, respectively. The quantification limits can be improved by adopting a more efficient pre\u2010concentration system such as purge\u2010and\u2010trap or thermal adsorption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>\n                      This analytical method will facilitate the use of hydrogen CSIA on chlorinated solvents, which can be beneficial in multi\u2010isotope approaches (coupling \u03b4\n                      <jats:sup>2<\/jats:sup>\n                      H values with \u03b4\n                      <jats:sup>13<\/jats:sup>\n                      C and\/or \u03b4\n                      <jats:sup>37<\/jats:sup>\n                      Cl values) in field site investigations where source identifications and contaminant behaviours are questioned.
