The HFID Model VE572 is a reliable and rugged, dual channel sequencing heated total hydrocarbon analyzer for low drift, high accuracy, sensitivity and stability. It uses our time proven hydrogen flame ionization detector (FID) in a heated oven to prevent the loss of high molecular weight hydrocarbons and to provide reliable performance in the analysis of high concentrations down to trace levels of THC contaminants in high purity gases, air and other gases.

All sample wetted components are integrated into the heated chamber. The two permanent heated sample filters are designed to be fully regenerated by back purging with compressed air or nitrogen. With only a few seconds needed for back purging, this technique allows uninterrupted measurements during cleaning of the sample filter while not in the sample mode. During back purging the sample filter, the sample line is also cleaned. The use of a stack probe filter is not necessary. The combustion air supply for the detector is built in. No expensive zero gas generator or external cylinder for synthetic air is needed. Automated sample sequencing and back purging of the sample filter can be done with one of our optional timing controllers.

Features:

  • All components in contact with sample are fully heated and controlled at 190 degC
  • Built-In sample pressure and sample pumps
  • Built-in combustion air supply, no extra burner air bottle needed
  • Maintenance free sample filter backpurge system allows both filters to be cleaned without dismantling (automatic purge optional)
  • Permanent heated 2 micron stainless steel mesh filter
  • “Overflow” calibration system for pressure less zero/span calibration
  • Automatic flame out control with alarm. An automatic fuel shut off valve is optional
  • Fast response less than 1 second
  • Low fuel consumption and very selective
  • Microprocessor PID-type temperature controller
  • Cold spot free coupling of the heated sample lines inside the heated oven optional
  • Remote control for sample, zero/span and backpurge is standard
  • Automatic or remote range change optional

Applications:

  • “Before” and “After” Abatement System Measurements to determine “destruction device” efficiency
  • EPA Method 25A compliance monitoring of source hydrocarbons (inlet and outlet)
  • Stack gas hydrocarbon emissions monitoring before and after an abatement system
  • Solvent recovery monitor for carbon bed break through
  • Thermal combustion compliance monitoring and testing
  • Catalytic converter compliance monitoring and testing
  • Carbon adsorption regeneration control
  • Measuring engine combustion efficiency
  • Raw exhaust vehicle emissions analysis
  • Hydrocarbon contamination monitoring in air and other gases
  • Carbon adsorption regeneration control
