Sitelab UVF-Trilogy Fingerprinting Analyzer

Overview

The Sitelab UVF-Trilogy Fingerprinting Analyzer (Model No. 7200-004-FNGP) is Sitelab’s most advanced benchtop ultraviolet fluorescence instrument, combining all four UV modules on a single chassis with eight factory calibrations covering GRO, EDRO, TPH-Oil and PAH standards. Seven Star LLC supplies it to environmental laboratories, forensic consultancies and oil and gas operators across Oman and the wider GCC who need to characterize a full range of petroleum contamination from a single instrument rather than running separate single-module analyzers. Every unit arrives factory calibrated across all four hydrocarbon ranges, ready for quantitative screening and qualitative fingerprinting as soon as it is unboxed.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 Fingerprinting Analyzer excites a solvent-extracted sample using four interchangeable UV modules, each fitted with an LED and optical filter tuned to a different class of petroleum hydrocarbon: GRO for gasoline-range organics, EDRO for extended diesel-range organics, TPH-Oil for heavier oil and grease fractions, and PAHs for polycyclic aromatic hydrocarbons. By measuring the fluorescence response across all four ranges on the same sample, the Sitelab UVF-Trilogy Fingerprinting Analyzer builds a hydrocarbon “fingerprint” that supports both quantitative concentration screening and qualitative source or age determination. This multi-module approach lets an analyst distinguish a fresh diesel release from a weathered crude oil spill, or identify which class of petroleum product is dominant in a mixed-contamination sample, in a way that a single-module UVF instrument cannot.

Engineering Design

The Sitelab UVF-Trilogy Fingerprinting 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 that in this configuration ships pre-loaded with all four modules and their factory calibrations. 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 fieldwork 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 analyzer can be deployed to a spill site, a marine terminal, or a remediation project for on-site fingerprinting work.

Key Features

The Sitelab UVF-Trilogy Fingerprinting Analyzer covers the full spectrum of petroleum hydrocarbon classes in one instrument: gasoline-range organics, extended diesel-range organics, TPH oil and grease, and polycyclic aromatic hydrocarbons, with eight factory calibrations spanning all four modules. It performs both quantitative measurements, for standard concentration screening against regulatory thresholds, and qualitative fingerprinting measurements, used to identify the source, age, or weathering state of a petroleum release. The instrument can test soil, water, and non-aqueous phase liquid (NAPL) samples, making it suitable for the full range of matrices encountered in an oil spill investigation or forensic analysis. The touch screen interface simplifies switching between the four calibrated modules, so a single operator can complete a full fingerprinting workup on one sample without changing instruments.

Industrial Applications

Seven Star positions the Sitelab UVF-Trilogy Fingerprinting Analyzer for oil spill source identification and forensic analysis, environmental site characterization involving mixed petroleum contamination, and bioremediation progress monitoring where operators need to track how a hydrocarbon fingerprint changes as weathering and biodegradation proceed. Oman’s oil and gas producers, environmental consultancies, and marine terminal operators across the GCC use this level of fingerprinting capability to determine liability in a spill event, distinguish a new release from historical contamination at a legacy site, and characterize crude oil or drilling mud composition during exploration and production activities. Laboratories offering forensic environmental testing services also rely on the Sitelab UVF-Trilogy Fingerprinting Analyzer to provide clients with a defensible, multi-parameter hydrocarbon profile rather than a single TPH number.

Because a single hydrocarbon release rarely fits neatly into one module’s detection range, the Sitelab UVF-Trilogy Fingerprinting Analyzer’s four-module design lets an investigator run the same sample against gasoline-range, diesel-range, oil-range, and PAH calibrations in sequence, building a complete contamination profile rather than a single data point. This is especially valuable at Omani and GCC sites with a long operating history, where multiple petroleum products may have been handled over the years and a full fingerprint is needed to separate a recent release from legacy background contamination. Seven Star’s technical team works with environmental consultancies and industrial operators across the region to structure a sampling and fingerprinting program around the analyzer’s capabilities. 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.

Clients who already operate a single-module UVF-Trilogy instrument for routine TPH, GRO, EDRO, or PAH screening sometimes ask whether it makes sense to add the Fingerprinting Analyzer to their toolkit rather than purchasing additional single modules separately. Seven Star’s engineering team generally recommends the four-module Fingerprinting configuration for any client whose work extends beyond routine regulatory compliance screening into forensic source attribution, litigation support, or bioremediation performance tracking, since those applications typically require the full hydrocarbon profile rather than a single analyte range. For a facility running strictly routine UST compliance monitoring on a known fuel type, a single-module analyzer such as the EDRO or GRO unit is usually the more cost-effective choice, and Seven Star is glad to help clients across Oman and the GCC work through that decision before committing to either configuration.

Sitelab UVF-Trilogy Fingerprinting continues to be available through Seven Star LLC for buyers across Oman and the GCC, with repeat mentions of Sitelab UVF-Trilogy Fingerprinting throughout this page reflecting its role as a core catalog item.
