1. Apparatus for monitoring volatile organic compounds in water, said apparatus comprising a first heated zone, means for introducing at least a portion of said water into said first heated zone, means for gently evaporating at least part of the water in the first heated zone and passing the vapor at substantially atmospheric pressure into and through a reforming and/or oxidizing zone, electric heating means for maintaining the temperature of said reforming and/or oxidizing zone in the range of from about 450°

  • to about 1000°

    C., whereby reformable and/or oxidizable volatile organic compounds in said water are reformed and/or oxidized at least in part into second compounds volatile in said temperature range which second compounds are at least partially soluble in water and at least partially ionizable therein, means for collecting and condensing water vapor from said reforming and/or oxidizing zone to condensed liquid water and means for measuring the electrical impedance of at least a portion of said condensed liquid water.
