Description

The ability to analytically quantify highly reactive volatile organic compounds (VOC) in cooling towers, heat exchangers, holding ponds, run-off water, and waste water is greatly enhanced with the Sample Transfer Stripper (Patent # 5448922) & solid state sensor offered by Analytical Systems Int’l./KECO R &D. The analyzer system utilizes many patented and exclusive features only available from Analytical Systems Int’l./KECO R & D.

The principle of operation requires a consistent free flowing liquid sample into a Sample Transfer Stripper unit which separates the liquids from the VOC’s. A hydrocarbon free consistently flowing air carrier then sweeps the VOC’s in a gaseous phase into the solid state sensor resulting in a quantitative analysis in ppb w, ppm w, or up to saturation levels. An optional liquid validation by Perm Tube TM (Patent #5,156,334) is available. This unattended on-line analysis is economically superior to inaccurate laboratory analyzers where unstable grab samples result in VOC’s deterioration that produce analytical errors. Downtime is reduced to less than 10% of the El Paso, TOC or Sparger methods and the economic pay out is increased because of reduced product loss. In one case, 12,000 pounds of product loss per day was quickly identified by this proven and accurate on-line analytical method. Speciation is only required once per month if total VOC’s are below 50 ppb w. This eliminates the need for expensive in-plant G.C. analysis of VOC’s. Analytical labs provide analytical speciation for $50 per sample (see G.C. EPA Method SW 846-8260B). Alternatively, a gaseous sample can be drawn from the Model 204L vent and speciation provided by the plant lab G.C.

See Patent #5,156,334, 5,448,922 ,Patents Pending based on letters that are available on request.
