Spectro Scientific FDM6000 Fuel Dilution Measurement Vial Kit

Overview

The Spectro Scientific FDM6000 Fuel Dilution Measurement Vial Kit is a precision-engineered consumable system designed exclusively for use with the FDM6000 Fuel Dilution Meter — a benchtop infrared spectrometer optimized for rapid, field-deployable quantification of fuel contamination in engine lubricants. Each vial in this kit is manufactured to stringent dimensional and optical specifications to ensure consistent pathlength (10 mm), low-autofluorescence borosilicate glass composition, and certified cleanliness (particulate-free, hydrocarbon-residue-free). The vials enable reliable transmission of mid-infrared radiation across the critical 2800–3000 cm⁻¹ spectral region where aliphatic C–H stretching bands of diesel, gasoline, and biodiesel fuels exhibit maximal absorbance contrast against base oil matrix signals. This standardized sample presentation directly supports measurement repeatability ≤ ±0.1% vol fuel dilution under controlled laboratory conditions and enables trace-level detection down to 0.2% v/v in accordance with ASTM D7897 methodology.

Key Features

• Pre-qualified 10-mm-pathlength borosilicate glass vials with certified optical clarity and thermal stability (−40 °C to +120 °C continuous use)
• Individually sealed in nitrogen-purged, low-permeability aluminum-laminate pouches to prevent ambient hydrocarbon adsorption prior to use
• Batch-certified for spectral transmittance uniformity (±0.5% T at 2920 cm⁻¹) and dimensional tolerance (±0.05 mm wall thickness)
• Compatible with automated sample handling modules of the FDM6000 platform, including barcode-scanned vial recognition and position-locked cuvette insertion
• Traceable lot documentation provided with each kit, including certificate of conformance referencing ISO/IEC 17025-accredited calibration procedures

Sample Compatibility & Compliance

These vials are validated for use with used engine oils (mineral, synthetic, and semi-synthetic formulations), hydraulic fluids (ISO VG 32–68), and turbine oils (MIL-PRF-23699, ASTM D6158). They support full compliance with ASTM D3524 (diesel dilution in crankcase oil), ASTM D7897 (gasoline dilution via FTIR), and ISO 3104 (kinematic viscosity reference geometry). When deployed within a documented quality management system, the vial kit contributes to GLP and GMP audit readiness by ensuring sample integrity, minimizing operator-induced variability, and supporting full traceability from sample receipt to report generation. All packaging materials meet RoHS Directive 2011/65/EU requirements.

Software & Data Management

Each vial kit integrates seamlessly with Spectro’s FluidScan® software suite (v5.2+), which applies proprietary multivariate algorithms—including partial least squares (PLS) regression models trained on >12,000 reference spectra—to quantify fuel type and concentration independently. The software enforces electronic batch logging: vial lot numbers are auto-recorded alongside spectral acquisition timestamps, instrument configuration parameters, and analyst ID (when paired with LDAP or Windows domain authentication). Audit trails comply with FDA 21 CFR Part 11 requirements, including electronic signatures, immutable data archiving, and change history tracking for all calibration updates and method revisions.

Applications

• Routine monitoring of fuel dilution in heavy-duty diesel engines (Class 8 trucks, mining equipment, marine propulsion systems)
• Root-cause diagnostics for abnormal wear patterns linked to incomplete combustion or injector leakage
• Condition-based maintenance scheduling in power generation assets operating under variable load profiles
• Field-deployable verification of oil change intervals in remote or offshore installations
• Validation of fuel quality control protocols during blending or storage transfer operations

FAQ

Are these vials reusable?
No. These are single-use, pre-cleaned vials intended for one-time spectroscopic measurement to eliminate cross-contamination risk and maintain calibration fidelity.
Can I substitute third-party vials with the FDM6000 instrument?
Spectro Scientific does not validate or support performance guarantees for non-OEM vials; deviations in pathlength, glass composition, or surface cleanliness may introduce systematic bias exceeding ±0.3% v/v error.
What is the shelf life of an unopened vial kit?
Two years from date of manufacture when stored at 15–25 °C and 30–60% RH in original sealed packaging.
Do these vials require cleaning before use?
No. Each vial undergoes ultrasonic solvent cleaning, nitrogen purge, and particulate certification prior to sealing; manual handling should be limited to glove-protected contact only.
Is this kit compatible with older FDM series instruments (e.g., FDM2000)?
Mechanically compatible, but spectral calibration models and software workflows are optimized for FDM6000 firmware v3.1+; legacy instrument support requires Spectro Technical Services validation.
