Buck Total Hydrocarbon Analyzer

Price per Unit (piece): $7,250.00

The Model HC-404 is a self contained, fixed wavelength infrared analyzer designed for rapid accurate analysis of total petroleum hydrocarbons in water, soil and sludge samples.

Perfect for ASTM methods D 7066-04, 418.1 & 413.2


  • Fixed wavelength 2930 cm-1 (3.42µ) allows for quick analysis without unnecessary scanning.
  • Digital readout in %T and absorbance, or in concentration mode for direct ppm readings.
  • Accommodates 10, 50, or 100 mm quartz cells for analysis to 1ppm or lower detection levels.
  • Built-in scale expansion and extended linear range for high concentration, using a simple 3-step calibration.
  • Peltier cooled PbSe detector provides greater than 2500 to 1 signal to noise ratio, resulting in the very best detection levels and excellent instrument stability.
  • Small foot print requires minimal lab space.
  • Hot quartz halogen source for the highest output possible.
  • Instrument simplicity. Intuitive controls allow for immediate operation.
  • analyzing water on offshore oil rigs
  • on-site oil in water analysis
  • monitoring of oil & water separation systems
  • TPH in soil at clean up sites or around underground oil tanks
  • measurement of oil residue in solvent from metal parts cleaning
  • Testing hydrocarbon levels in recycled solvents
