Fetzpahs Consulting is a provider of practical solutions to problems in the chemistry and analysis of petroleum-related materials and the polycyclic aromatic hydrocarbons (PAHs). The size of projects can be large or small, with rates that are flexible enough to meet budgetary constraints.

The principal, John C. Fetzer, is a recognized world-class expert in the chemistry and analysis of the polycyclic aromatic compounds. Specialist in the development of separation and compositional analysis methods aimed particularly at crude oil, its distillate fractions (including asphalt and residuum), catalytically-processed petroleum products (waxes, mineral oils, lube oil basestocks, fuels, and intermediate oils, petrochemical products, and additives. He has a high-level of expertise in high-performance liquid, supercritical fluid, gel-permeation and gas chromatographies, and fluorescence and UV absorbance measurements.
