X-Wand® HVOC Analyzer
X-Wand® was validated at military sites, where it detected TCE in soil and water down to parts per billion. 
Products & Licensing Opportunities


Halogenated volatile organic compounds (HVOCs) are among the most common contaminants in the United States. The EPA has identified nearly 70,000 affected industrial and residential sites, and the Department of Defense has targeted approximately 9,000 military sites for cleanup. HVOCs are introduced into the environment as refrigerants, de-greasers, de-waxers, fumigants, dry cleaning solvents and aerosol propellants. Despite their prevalence, screening for HVOCs has been costly and problematic. The most common VOC field screening tools don't specifically detect HVOC pollutants.

X-Wand®, developed by WRI, makes HVOC detection fast, easy, accurate and economical. The portable, hand-held instrument uses a heated diode sensor, the same type used to detect refrigerant leaks, for rapid evaluation of soil or water.  The U.S. Department of Energy has recognized its potential for cleanup at Brownfield sites.  

X-Wand® offers these advantages:

  • Distinguishes halogenated volatile organic compounds from other VOCs, such as gasoline.
  • Quickly identifies "hot spots," increasing the efficiency of environmental assessments and cleanup.
  • Provides real-time monitoring during and after cleanup.
  • Eliminates unnecessary laboratory analyses and costs.
  • Detects TCE down to about 1 part per billion―a level comparable to that of EPA-approved laboratory methods.
  • Requires very little training.
  • Described in ASTM Standard Method D7203.
