LUMEX Fluorat-02-5M UV/Fluorescence Oil Content Analyzer

Overview

The LUMEX Fluorat-02-5M UV/Fluorescence Oil Content Analyzer is a field-deployable, multi-modal optical instrument engineered for quantitative determination of petroleum hydrocarbons and other fluorogenic or UV-absorbing analytes in aqueous, semi-aqueous, and extractable matrices. It operates on dual detection principles: ultraviolet spectrophotometry (UV-Vis) and synchronous fluorescence spectroscopy—both compliant with internationally recognized standard methods including EPA Method 1664, HJ 970–2018 (China), SL 366–2006, GB 17378.4–2007, and PNDF 14.1:2:4.128–98. Unlike conventional gravimetric or infrared-based oil-in-water analyzers, the Fluorat-02-5M leverages high-intensity pulsed xenon lamp excitation and patented triple-channel optical path design to minimize stray light, photometric drift, and signal attenuation—enabling robust performance under variable ambient conditions and across wide dynamic concentration ranges.

Key Features

• Triple-channel optical architecture with independent excitation/emission pathways—enhancing signal-to-noise ratio and measurement reproducibility (RSD < 2% at 1 mg/L oil standard)
• Single-channel adaptive range design: eliminates manual range switching; supports seamless quantification from sub-ppm to >100 mg/L without dilution or hardware reconfiguration
• Pulsed xenon lamp source (250–900 nm spectral coverage) with >10⁹ lifetime cycles—ensuring long-term photometric stability and eliminating mercury-lamp disposal concerns
• Integrated non-volatile memory storing up to 100 calibration curves, instrument configurations, and audit-trail metadata—fully traceable per GLP/GMP data integrity requirements
• Low-toxicity, low-volume reagent protocol compatible with Montreal Protocol compliance; typical solvent consumption ≤ 2 mL per analysis
• Onboard color TFT display with intuitive menu navigation; optional PC-based software (Fluorat Control Suite) supporting remote operation, method validation, and 21 CFR Part 11–compliant electronic signatures

Sample Compatibility & Compliance

The Fluorat-02-5M accepts liquid samples directly—including raw wastewater, produced water, cooling tower effluents, steam condensates, rainwater runoff, and solvent extracts (e.g., n-hexane or cyclohexane). It is validated for use with EPA 1664-compliant extraction procedures and exhibits minimal interference from methanol, ethanol, suspended solids (< 50 mg/L), or turbidity (up to 200 NTU). The system meets ISO/IEC 17025 method validation criteria for linearity (r² ≥ 0.999), limit of detection (LOD = 0.2 mg/L), and recovery (92–105% across 0.5–50 mg/L spiked matrices). Its design conforms to IEC 61010-1 safety standards and CE marking requirements for portable analytical instrumentation.

Software & Data Management

The Fluorat Control Suite provides full instrument control, real-time spectral visualization, automated peak integration, and customizable report generation (PDF/CSV). All calibration events—including single-point verification, multi-point linear/nonlinear regression, and bracketing checks—are timestamped and user-annotated. Audit trails record operator ID, parameter changes, calibration history, and result modifications—supporting FDA 21 CFR Part 11 compliance when deployed in regulated environments. Data export supports LIMS integration via OPC UA or direct USB transfer; no cloud dependency required.

Applications

• Regulatory monitoring of petroleum hydrocarbons in municipal and industrial wastewater discharges (per China’s “Six Mandatory Water Quality Parameters” framework)
• Routine surveillance of oil-in-water in power plant cooling systems, hydropower station intake channels, and refinery process streams
• Emergency response to oil spills: rapid on-site screening of surface water, soil leachates, and containment pond effluents
• Quality control of fuel oils (diesel, gasoline, lubricants, hydraulic fluids), crude oil fractions, and condensate streams
• Multiparameter analysis of benzene derivatives (e.g., phenol, styrene), amino compounds, and polycyclic aromatic hydrocarbons (PAHs) in environmental and food safety labs

FAQ

Does the Fluorat-02-5M require hazardous solvents like carbon tetrachloride?

No—it is optimized for low-toxicity extractants (e.g., n-hexane, cyclohexane) and complies with Montreal Protocol phase-out schedules.
Can it quantify oil in highly turbid or colored samples?

Yes—its synchronous fluorescence mode and triple-channel compensation reduce scattering and background interference significantly.
Is multi-point calibration mandatory for routine use?

Not required: single-point verification suffices for daily QC; multi-point calibration is recommended for method validation or matrix-specific applications.
What maintenance is required beyond lamp replacement?

Annual optical alignment verification and cuvette cleaning; no consumable optics or detectors—xenon lamp life exceeds 10⁹ pulses.
Is the instrument suitable for ISO 17025-accredited laboratories?

Yes—full traceability, uncertainty estimation tools, and electronic audit logs support accreditation documentation requirements.
