Sitelab UVF-Trilogy GRO Analyzer

Overview

The Sitelab UVF-Trilogy GRO Analyzer (Model No. 7200-004-GRO) is a benchtop ultraviolet fluorescence instrument dedicated to gasoline range organics screening across the C6–C10 carbon range, capturing BTEX compounds and the other volatile petroleum hydrocarbons that characterize light-refined fuel contamination. Seven Star LLC supplies the analyzer to environmental consultancies, remediation contractors and fuel terminal operators across Oman and the wider GCC who need same-day gasoline range hydrocarbon data on soil or water samples without shipping to an outside laboratory. Every unit arrives factory calibrated using Sitelab’s own GRO reference standards, so a technician can begin measuring samples as soon as it is unboxed and connected to power.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 GRO Analyzer excites a solvent-extracted sample with an ultraviolet LED tuned to the GRO module’s specific wavelength and optical filter, then measures the resulting fluorescence of the aromatic hydrocarbons present at gasoline-range volatility. The instrument reports a minimum detection limit of 0.5 ppm across the C6–C10 range, and results from the Sitelab UVF-Trilogy GRO Analyzer compare well to EPA Method 8015, VPH methods, and other laboratory TPH-GRO gas chromatography test methods, giving field teams a fast screening tool that correlates meaningfully with confirmatory lab analysis. Because gasoline range organics evaporate and weather faster than heavier diesel or oil fractions, rapid on-site measurement with the GRO Analyzer captures contamination signatures that could otherwise be lost by the time a sample reaches an off-site laboratory.

Engineering Design

The Sitelab UVF-Trilogy GRO Analyzer shares the same rugged benchtop chassis as the rest of the Trilogy platform: an intuitive touch screen interface, storage for up to 18 calibrations in onboard memory, and a snap-in UV module bay so the GRO module can be combined with EDRO, TPH Oil, or PAHs modules on a single instrument as a project’s scope broadens. Every unit ships with a glass sample cuvette and a solvent dispenser bottle included, with spare quartz cuvettes available separately under part number QCUV-10MM. For field deployments beyond 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 GRO Analyzer can travel to a fuel depot, tank farm, or underground storage tank removal site.

Key Features

The Sitelab UVF-Trilogy GRO Analyzer detects BTEX and other volatile gasoline-range hydrocarbons with a minimum detection limit of 0.5 ppm, delivering low-ppm sensitivity without requiring gas chromatography equipment on site. Calibration kits are matrix-specific—part number CAL-025M is methanol-based for soil analysis while CAL-025H is hexane-based for water analysis, each containing five calibration standards—so the GRO Analyzer can be tuned precisely to the sample matrix under investigation. The touch screen interface walks operators through sample measurement, calibration, and mode selection in a few taps, and results are available in minutes rather than the days a laboratory turnaround typically requires.

Industrial Applications

Seven Star positions the Sitelab UVF-Trilogy GRO Analyzer for gasoline release investigations, jet fuel and heating oil contamination screening, diesel and other light-refined petroleum contamination assessments, and underground storage tank (UST) removal site closure sampling. Oman’s fuel retail network, aviation fueling depots, and the GCC’s dense underground storage tank infrastructure all generate a steady need for fast, defensible gasoline range hydrocarbon data, and the GRO Analyzer lets environmental consultants triage which soil or water samples genuinely require confirmatory VPH or GC laboratory analysis before committing project budget to outside testing. Marine bunkering terminals and vehicle fueling stations across the region likewise rely on the Sitelab UVF-Trilogy GRO Analyzer to screen for gasoline-range leaks during routine tank integrity monitoring.

Sites where gasoline-range contamination is only part of the picture can pair the Sitelab UVF-Trilogy GRO Analyzer with additional EDRO, TPH Oil, or PAHs modules on the same chassis, or step up to the four-module Fingerprinting Analyzer for full forensic characterization of a mixed petroleum release. Seven Star’s technical team helps clients in Oman and across the GCC select the right module configuration before committing to a purchase, so the instrument continues to match the project’s testing needs as they evolve over time. Working closely with plant engineers in the region, 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 gasoline range hydrocarbons volatilize quickly once a sample is exposed to air, laboratories often report lower TPH-GRO concentrations than what was actually present in the ground at the time of sampling, simply due to loss during shipping and storage. Running the Sitelab UVF-Trilogy GRO Analyzer on site captures a reading close to the true in-situ concentration, which is particularly valuable when regulatory decisions in Oman or elsewhere in the GCC hinge on whether a gasoline release exceeds a specific screening threshold. Consultants who pair on-site GRO screening with periodic confirmatory laboratory samples typically end up with a more defensible overall data set than relying on off-site analysis alone.
