Sitelab

Sitelab, founded in 1998 in West Newbury, USA, builds ultraviolet fluorescence (UVF) analyzers for measuring petroleum hydrocarbons on site instead of waiting for a laboratory report. Seven Star LLC, an independent supplier in Oman, lists the Sitelab UVF-Trilogy in its TPH, GRO, EDRO, PAH and fingerprinting configurations, together with the handheld UVF-500D hydrocarbon analyzer for field work.

Sitelab analyzers listed here

Two instruments make up the range on this page. The UVF-Trilogy is the bench instrument, and the five listings differ by the analysis it is set up for:

• TPH oil: total petroleum hydrocarbons
• GRO: gasoline range organics
• EDRO: extended diesel range organics
• PAHs: polycyclic aromatic hydrocarbons
• Fingerprinting: comparing the fluorescence pattern of a sample with known products

The UVF-500D is a handheld, battery-operated unit with two optical channels, used mainly for oil in water and for heavier oils in soil. With UVF, the sample is extracted in solvent and the aromatic compounds in the extract fluoresce under ultraviolet light; the instrument reads that signal against calibration standards.

Where Sitelab UVF testing is used

The typical users are environmental consultants, remediation contractors and oilfield laboratories who need a number the same day: soil from a spill or tank excavation, sediment, groundwater, and oil in water. In the GCC this usually means contaminated land assessment and produced water checks. Screening results are normally confirmed by a laboratory method where a regulator requires it.

Ordering a Sitelab analyzer: what we need

Tell us which hydrocarbon ranges you need to report (GRO, EDRO, TPH, PAH), the sample types, and the concentration range you expect. For an existing instrument send the model and serial number, and say which calibration kits and consumables you need to replace. With that we can ask for the correct configuration and accessories in one quotation.
