| Abstract: | A new technique of separation-analysis, splitless injection/Cu~(2 ) precolumn-capillary GC/FTIR,is introduced by this paper. By this new technique, solvent effects can be eliminated completelyand larger volume of sample can be injected. The sensitivity of the system is 1-2 order of mag-nitude higher than ordinary GC/FTIR. The techniqus has successfully been used for analysis ofwater in the Yangtze River. So for 28 pollutants have been identified, of wnich 12 componentsare priority pollutants. |
