Sitelab Corporation manufactures portable laboratory instruments and test kits used to measure concentrations of petroleum hydrocarbons in soil, sediment and water on-site. Popular tests include TPH, GRO, DRO, VPH, EPH, BTEX and PAHs. Customers use our UVF analyzers to help make better field decisions when investigating and cleaning up petroleum sites.
Sitelab's Ultraviolet Fluorescnece (UVF) technology is very sensitive to gasoline, jet fuel, diesel, coal tar, crude oil and many other types of PHCs. Hydrocarbon fingerprinting can also be performed for forensic analysis. Sitelab is the most accurate tool on the market. Test results directly correlate to certified laboratory methods, but at a much lower cost.
Test kits are available for preparing samples for analysis. These kits are used for soil, sediment or water. Samples are extracted in solvent and then analyzed for hydrocarbon concentration. Our instruments are easy to operate.
UVF is a very selective and quantitative detection method. Aromatic hydrocarbons, which are abundant in petroleum, both excite and emit energy at specific wavelengths. Samples are measured on a linear curve using certified calibration standards sensitive to the wavelengths of interest. The concentration is displayed in only a few seconds. Minimum detection limits are in the low PPM or PPB range.

Sitelab has several different instruments to choose from, which vary depending on your needs and application. Our calibration standards are specially formulated to generate very accurate results. See examples below:
- GRO: Gasoline Range Organics Hydrocarbons. This includes BTEX and other volatile compounds in the C6 to C10 range. Results correlate well to EPA Method 8015-GRO, VPH or similar GC methods.
- EDRO: Extended Diesel Range Organic Hydrocarbons. This includes hydrocarbons in the C10 to C36 diesel and oil range. Results correlate well to EPA Method 8015-DRO, EPH or similar GC methods.
- PAHs: Polycyclic Aromatic Hydrocarbons. Results correlate well to the 16 PAHs reported by EPA Method 8270 by GC/MS.
- TPH-Oil: Total Petroleum Hydrocarbons. This includes hydrocarbons in the C10 to C50 range. This test is used for 'Oil & Grease' applications testing crude oil.
The U.S. EPA evaluated Sitelab and six other manufacturers for measuring total petroleum hydrocarbons in soil. Tetra Tech, Inc. was contracted to manage this $800,000 project.
Sitelab tested over 200 samples using our UVF-3100A analyzer for both Gasoline Range Organics, Extended Diesel Range Organics and Total Petroleum Hydrocarbons (TPH as combined GRO and EDRO). Sitelab was the only developer who performed and reported TPH as well as GRO and EDRO separately, just like the reference laboratory.
'The UVF-3100A exhibited the following desirable characteristics of a field TPH measurement device; (1) good accuracy, (2) good precision, (3) high sample throughput, (4) low measurement costs and (5) ease of use.'
Sitelab Corporation has been selling and renting field-based test equipment since 1998. Our analyzers are used all over the world. We also provide laboratory services. See 'SERVICES' for pricing and turnaround time.
Not sure what type of TPH you have on your site?
The UVF-3100D is fitted with 3 sets of optical filters used to detect gasoline range and polyaromatic range contaminants separately from one another.
By testing a sample for GRO, Total PAH and Target PAH concentrations using Sitelab's GRO and PAH calibration kits, the ratios or 'signatures' exhibited can be used identify the type or age of petroleum contamination.
This forensic method is useful on sites contaminated by unknown petroleum sources or to see if the contaminant is fresh or weathered. Soil, sediment, water or oil samples can be analyzed.
Need laboratory analysis? We specialize in testing oil on metals serving the food, drug and medical divice manufacturers. Applications incude testing parts and surfaces for hydrocarbon content to ensure they are clean and oil free.
» Environmental consultants use Sitelab to investigate where, how much and what type of contamination exists on a site.
» Contractors use Sitelab to help guide excavation activities to clean up the vertical and horizontal extent of petroleum resulting from underground storage tanks (USTs).
» Scientists uses Sitelab to fingperprint and identify the type and age of petroleum.
» Government regulators and emergancy response crews use Sitelab to assist with oil spills, natural disasters or military activities.
» Property owners with fuel oil spills send samples to Sitelab's laboratory for fast, affordable and reliable test results.
» Field technicians use Sitelab to monitor levels of TPH for bioremediation, disposal and other treatment methods.
» Large industrial sites, power plants, Brownfields, tank farms and refineries where high numbers of samples must be tested without the high cost and time delays of conventional laboratory analysis.
» Manufacturering companies test metal parts for quality control to ensure their products are free of oil.
