Sitelab Corporation manufactures portable test kits to measure petroleum contamination in soil, sediment and water. Sitelab uses ultraviolet fluorescence technology (UVF) to detect concentrations of hydrocarbons commonly found in gasoline, jet fuel, diesel fuel, heating oils, waste oils, coal tars, coal ash, creosote, crude oils and many other petroleum products.

Who's using our products?

» Environmental consultants and engineers use Sitelab during site assessments to determine where, how much and what type of contamination exists on a site.

» Contractors use Sitelab to help guide excavation and remediation activities, in order to clean up the vertical and horizontal extent of petroleum contamination.

» Power plants, Brownfields and other large industrial sites where high numbers of samples must be tested without the high cost and time delays of conventional laboratory analysis.

» Government agencies use Sitelab to monitor and check contaminated sites ranging from natural disasters and military activities to regulatory enforcement.

» Homeowners and property owners who have heating oil spills and resulting contamination, send samples to Sitelab for fast, affordable and reliable test results.

Sitelab’s accuracy, speed and low cost per sample allows customers to delineate contaminated sites much more thoroughly, while minimizing the number of samples sent off-site for lab confirmation. Savings in disposal costs, treatment, time and labor are also achieved. Our technology has been evaluated by the U.S. Environmental Protection Agency, where it out performed all the other leading manufacturers. Sitelab has carefully developed our technology to directly correlate to conventional laboratory GC test methods. Detection limits are in the low ppb range.

Sitelab's portable field analyzers use ultraviolet fluorescence technology, a very selective detection method useful for measuring many types of petroleum contaminants. UVF spectrometry's principle of operation relies on the electronic configuration of the molecular structure for each compound. Aromatic hydrocarbons, which include carcinogenic compounds like benzene, naphthalene, benzo[a]pyrene, etc., both excite and emit energy at specific wavelengths. The fluorometer's response of each sample is measured by the instrument on a linear, 5-point calibration curve using certified standards sensitive to the wavelengths of interest. Samples are extracted in methanol solvent using disposable test kits and then placed into the analyzer for analysis, where the concentration is displayed in only a few seconds.

Different petroleum products contain different types and amounts of aromatic hydrocarbons, which fluoresce differently from one another. Many contaminated sites also contain weathered fuel products which have degraded and changed in composition over time. In addition, most conventional laboratories use a variety of U.S. EPA test methods using Gas Chromatography (GC) instrumentation to separately report gasoline range, diesel range and other specific hydrocarbon groups.

Fortunately, Sitelab provides a variety of different types of UVF Calibration Kits to choose from in order to best match the source of your spill and provide maximum performance when comparing your field results to the confirmatory lab. Since our analyzers are calibrated using similar types of certified standards laboratories use for GC analysis and are fitted with specially developed optical filters, test results generated directly correlate, providing very accurate and reliable results at only a fraction of the cost and time.
