UIS Organic Laboratory offers a C10-C40 TPH analysis that has been developed in-house. Using certified diesel and motor oil standards, this method enables us to determine the total hydrocarbon concentration over the diesel/oil range.
Different methods of extraction are used for soil and water samples.
For water samples a liquid-liquid extraction is used, while an Accelerated Solvent Extractor is used for the extraction of soils. The resulting extracts are then analyzed using liquid injection on a Bruker 450GC-300MS Triple Quadrapole .
As a standard we report a C10-28, C28-40 and a C10-40 total, but specific TPH breakdowns between C10 and C40 can be tailored to client specifications at a slightly higher price (See Pricelist).
