Sitelab UVF-Trilogy PAHs Analyzer

Overview

The Sitelab UVF-Trilogy PAHs Analyzer (Model No. 7200-004-PAHS) is a benchtop ultraviolet fluorescence instrument built to screen for polycyclic aromatic hydrocarbons across the C10–C22 carbon range, targeting the 16 EPA-regulated PAH compounds including benzo[a]pyrene. Seven Star LLC supplies the Sitelab UVF-Trilogy PAHs Analyzer to environmental laboratories, remediation contractors, and industrial site operators across Oman and the wider GCC region who need low-ppb PAH screening on soil and water samples without the multi-week turnaround of GC/MS confirmatory testing. Every Sitelab UVF-Trilogy PAHs Analyzer arrives factory calibrated using Sitelab’s own PAH reference standards, so laboratory staff and field technicians can generate quantitative results as soon as the unit is set up.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.

Working Principle

The Sitelab UVF-Trilogy PAHs Analyzer excites a solvent-extracted sample with an ultraviolet LED tuned to the PAHS module’s specific wavelength and optical filter, measuring the fluorescence response of the aromatic ring structures characteristic of polycyclic aromatic hydrocarbons. The instrument achieves a minimum detection limit of 0.05 ppm, placing it in the low ppb detection range needed for regulatory PAH screening, and results from the Sitelab UVF-Trilogy PAHs Analyzer compare well to EPA Method 8270 and other GC/MS test methods as the sum of the 16 regulated PAH compounds, as well as the draft Method 8670 that has been circulated specifically for UVF-based PAH measurement. Because PAHs are combustion byproducts that persist strongly in soil and sediment, the analyzer’s sensitivity down to the low-ppb range is essential for meeting the stringent screening levels regulators typically apply to these compounds.

Engineering Design

The Sitelab UVF-Trilogy PAHs Analyzer shares the same rugged benchtop housing as the rest of the Trilogy family: an intuitive touch screen interface, storage for up to 18 calibrations in onboard memory, and a snap-in UV module bay so the PAHS module can be paired with GRO, EDRO, or TPH Oil modules on the same chassis. Every unit ships with a glass sample cuvette and solvent dispenser bottle included, and spare quartz cuvettes are available separately under part number QCUV-10MM. For work away from Seven Star’s client sites in Oman, the optional heavy-duty waterproof field case (part number 7200-UVFCASE) adds a rechargeable 120V battery so the Sitelab UVF-Trilogy PAHs Analyzer can be deployed to a coal ash impoundment, asphalt plant, or contaminated sediment sampling location.

Key Features

The Sitelab UVF-Trilogy PAHs Analyzer detects target PAHs at a minimum detection limit of 0.05 ppm, well into the low-ppb range regulators expect for compounds like benzo[a]pyrene. Calibration is matrix-specific—part number CAL-060M is a methanol-based kit for soil analysis and CAL-060H is a hexane-based kit for water analysis—letting the PAHS Analyzer be tuned precisely to the sample type under investigation. The touch screen interface simplifies sample measurement, calibration, and mode selection, and a full PAH screening result is available in minutes rather than the multi-week turnaround typical of outside GC/MS laboratory analysis.

Industrial Applications

Seven Star positions the Sitelab UVF-Trilogy PAHs Analyzer for fuel oil and waste oil contamination screening, asphalt and sealcoat product testing, creosote and coal tar site investigations, coal ash impoundment monitoring, and contaminated sediment and storm water runoff assessment. Oman’s road construction and asphalt production industry, along with power generation facilities handling coal ash and former manufactured gas plant sites across the GCC, all generate PAH screening requirements that the Sitelab UVF-Trilogy PAHs Analyzer can address on site rather than waiting on laboratory GC/MS confirmatory results. Marine terminal operators and port authorities investigating creosote-treated piling contamination also rely on the PAHs Analyzer to triage sediment sampling programs before committing to expensive laboratory analysis of every sample.

Because PAH contamination frequently coexists with diesel-range or oil-range hydrocarbons at the same site, the Sitelab UVF-Trilogy PAHs Analyzer’s snap-in module design lets clients add EDRO or TPH Oil modules to the same chassis, or step up to the four-module Fingerprinting Analyzer for complete forensic characterization of a mixed petroleum and PAH release. Seven Star’s technical team can help environmental consultancies in Oman and across the GCC determine the right module configuration for a given site’s contamination profile before purchase. With engineering support in Muscat, Seven Star LLC supplies the Sitelab UVF-Trilogy to laboratories, industrial facilities, and research institutions throughout Oman, Muscat, and the Sohar and Salalah economic zones, with technical support with selection.

Because many PAH compounds bind tightly to soil organic matter and sediment particles, sample preparation and extraction efficiency matter as much as the analytical instrument itself. Sitelab’s calibration kits and extraction procedures for the Sitelab UVF-Trilogy PAHs Analyzer are designed around this behavior, giving consultants and laboratory technicians in Oman and the GCC a screening workflow that produces results consistent with the sample preparation practices used in confirmatory GC/MS laboratory testing, rather than a shortcut that sacrifices data quality for speed.
