SPECIALTY CARBON ANALYSIS: We use a programmable infrared furnace as well as conventional resistance furnaces to provide controlled temperature gradients up to 1000° C to allow us to monitor CO2 evolution from the pyrolysis or combustion of various materials. These techniques are valuable for distinguishing between organic and elemental carbon, both in bulk samples and on surfaces.


  1. Several different TOC methods are available for both liquids and solids, including high temperature combustion for micro and macro solid samples as well as water samples. Hot persulfate and uv-promoted persulfate methods are available for trace TOC in water
  2. Trace implies a detection limit below 1 mg/l (usually 0.05 mg/l)
  3. Quadruplicate analyses required for EPA SW-846-9060
  4. Lloyd Kahn EPA Method
  5. Separation of dissolved organic constituents into six major groups
  6. The TOC and SUVA packages include certified sampling bottles, cooler, field blank, fortified sample and laboratory QC and reporting on forms as required by the State of Colorado for sampling one treated and one untreated water source
  7. For State of Colorado reporting, SUVA package also requires the TOC package
