Sipo Environment OIL-IR-BX Portable Infrared Spectrophotometric Oil Analyzer

Overview

The Sipo Environment OIL-IR-BX Portable Infrared Spectrophotometric Oil Analyzer is a field-deployable analytical instrument engineered for quantitative determination of total petroleum hydrocarbons (TPH), animal and vegetable oils, and grease content in aqueous matrices—including surface water, wastewater, leachate, and industrial effluents—as well as semi-volatile oil residues in solid samples and cooking fume particulates. It operates on the principle of mid-infrared absorption spectroscopy, specifically targeting characteristic C–H stretching vibrations (2800–3000 cm⁻¹) and C=O carbonyl bands (1700–1750 cm⁻¹) to differentiate hydrocarbon classes. Unlike benchtop FTIR systems, the OIL-IR-BX integrates optical path stabilization, real-time wavelength calibration, and solvent vapor compensation—enabling robust performance under variable ambient conditions without laboratory-grade environmental control.

Key Features

• Integrated 8-inch industrial all-in-one PC with Windows XP or later OS, providing deterministic software execution and long-term firmware compatibility for regulatory documentation workflows.
• Onboard lithium-ion battery system with real-time voltage monitoring, supporting ≥500 consecutive measurements or ≥8 hours of continuous operation—validated under ISO/IEC 17025 field-use protocols.
• Compact monolithic chassis (450 × 320 × 150 mm; 10 kg net weight) designed for rapid deployment in emergency response scenarios, mobile labs, and remote sampling stations.
• Dual-solvent compatibility: fully validated for use with both tetrachloroethylene (PERC) and carbon tetrachloride (CTC), with automated solvent blank correction and spectral baseline drift compensation.
• Embedded automatic extraction module with standardized EPA Method 1664-compliant sample vials, enabling on-site liquid–liquid extraction prior to IR measurement—eliminating transport-induced analyte loss or degradation.
• Self-calibrating optical alignment: dynamically identifies and locks onto reference absorption peaks (e.g., 2930 cm⁻¹, 2960 cm⁻¹, 3030 cm⁻¹) during each scan to maintain wavelength accuracy within ±0.5 cm⁻¹ over instrument lifetime.

Sample Compatibility & Compliance

The OIL-IR-BX meets methodological requirements for EPA Method 1664A (petroleum hydrocarbons in water), ISO 9377-2:2000 (hydrocarbon content in water by IR), and HJ 637–2018 (Chinese national standard for petroleum and animal/vegetable oil determination). It accommodates aqueous samples (0.1–100 mL volume), suspended solids (filtered or centrifuged), and particulate-laden cooking fumes collected on quartz fiber filters. All measurement data are traceable to NIST-traceable mineral oil standards (SRM 2781), with documented uncertainty budgets available per ISO/IEC 17025 Clause 7.6. The instrument’s design supports GLP-compliant audit trails when paired with optional time-stamped digital log export.

Software & Data Management

The embedded software suite provides full spectral acquisition, peak integration, multi-point calibration curve generation (linear, quadratic, or cubic), and statistical reporting (mean, SD, RSD, confidence intervals). Each measurement generates a timestamped .CSV file containing raw absorbance spectra (1 cm⁻¹ resolution), processed concentration values, and diagnostic flags (e.g., solvent saturation, pathlength error, spectral noise index). Data export conforms to ASTM E1382-16 format for LIMS integration. Optional FDA 21 CFR Part 11 compliance package includes electronic signatures, role-based access control, and immutable audit logs with hash-verified data integrity.

Applications

• Routine monitoring of oil discharge compliance at municipal wastewater treatment plants and industrial outfalls.
• Emergency spill assessment following pipeline ruptures, tanker groundings, or storage tank failures—providing actionable data within minutes of sample collection.
• Verification of oil removal efficiency across coalescing separators, API tanks, and dissolved air flotation units.
• Regulatory inspection of food service establishments for grease trap effluent quality (per local health code §4-202).
• Research-grade quantification of biodegradation kinetics in microcosm studies using stable-isotope-labeled hydrocarbons.

FAQ

Does the OIL-IR-BX require external calibration standards for daily operation?
No—each analysis includes an internal solvent blank scan and reference peak auto-alignment; however, periodic verification using certified oil standards (e.g., NIST SRM 2781) is recommended every 30 days per ISO/IEC 17025 Clause 7.7.
Can the instrument distinguish between mineral oil and biodiesel contamination?
Yes—the spectral deconvolution algorithm resolves C–H aliphatic (2920 cm⁻¹), aromatic (3000–3100 cm⁻¹), and ester carbonyl (1745 cm⁻¹) bands, enabling semi-quantitative differentiation when combined with reference library matching.
Is method validation support available for regulatory submissions?
Yes—Sipo Environment provides IQ/OQ documentation templates, method transfer protocols, and third-party validation reports aligned with USP , EP 2.2.46, and ISO/IEC 17025 Annex A.
What maintenance is required for field longevity?
Annual optical path cleaning and desiccant replacement; no consumable optics or lamps—solid-state IR source and DTGS detector ensure >50,000-hour operational life.
