Total Petroleum Hydrocarbon TPH Analyzer



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 method D 7066-04, EPA method 418.1 & EPA method 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
  • 2 year warranty
  • Leasing options available for domestic customers




We have 2 New TD-360 Mini-Fluorometer still in original package and complete with accessories. Recently factory tested and approved. Being sold “as is” with no warranty, spare parts or service available from us.

The TD-360 Mini-Fluorometer is a cost effective, variable-wavelength filter fluorometer designed for quick, easy, and accurate fluorescence measurements. The multi-wavelength capability makes it appropriate for a wide variety of molecular biology applications.

Features of the TD-360

  • Flexible: Removable optical filter holder and user-changeable light source allow the quantitation of assays of differing wavelengths using a single instrument.
  • Sensitive: Accurately measure DNA down to 500 pg/mL using PicoGreen® and 5 ng/mL using Hoechst 33258.
  • Selective: Quantitate dsDNA in the presence of proteins, RNA, and nucleotides.
  • Low Volume Analysis: Measure as little as 100 pg of DNA using PicoGreen® and 1 ng using Hoechst 33258 in 3 µL of solution.
  • Stable: Reference path monitors light source and corrects for fluctuations due to aging or electronic drift.
  • Fast & Simple: Quick instrument warm-up time and an ergonomically designed sample chamber make analyses quick and easy.
