Portable Hydrocarbon Analyzer

The detection and measurement of petroleum hydrocarbons in water was historically achieved by sampling followed by gas chromatography or infrared analysis. With the advent of the Portable Hydrocarbon Analyzer, the worlds first patented fiber optic chemical sensor (FOCSR) built into a portable analyzer, it is now possible to measure ppm levels of petroleum hydrocarbons in vapor or ground water via a sampling well, in the field and in real time.

The portable hydrocarbon analyzer is designed to meet field monitoring requirements. In the analytical mode, it gives fast and accurate quantitative data for petroleum hydrocarbons in water and vapor. The data correlates very well with lab gas chromatographic analysis. In the screening mode, it offers fast relative data on petroleum hydrocarbon contamination, tracking field gas chromatograph data for TPH, and responds strongly to BTEX components.

Typical Applications Include:

  • Remediation Monitoring
  • Site Assessment
  • Well Plume Monitoring
  • Storm/Waste Water Monitoring
  • Hydrocarbon Breakthrough
  • Leak Detection AST/UST
