Spectro Scientific FDM6000 Fuel Dilution Monitor Vial Kit (50-pk)

Overview

The Spectro Scientific FDM6000 Fuel Dilution Monitor Vial Kit is a purpose-engineered consumable component designed exclusively for use with the FDM6000 Fuel Dilution Monitor—a benchtop infrared (IR) spectrometer optimized for rapid, quantitative detection of fuel contamination in lubricating oils. The vials serve as standardized sample containment vessels that ensure optical path consistency, thermal stability, and chemical compatibility during FTIR-based fuel dilution analysis. Each vial is precision-molded from high-transmittance, IR-transparent polypropylene to minimize spectral interference across the critical 700–4000 cm⁻¹ range, enabling reproducible baseline alignment and accurate peak integration for hydrocarbon signature bands (e.g., C–H stretch at ~2960 cm⁻¹ and ~2870 cm⁻¹). Unlike generic sample tubes, these vials are calibrated to hold 1.0 mL ± 0.02 mL of oil sample and feature a conical bottom geometry to facilitate complete aspiration and reduce residual carryover—critical for maintaining measurement integrity across high-throughput laboratory or field-deployed maintenance environments.

Key Features

• Pre-qualified for ASTM D7413-22 compliance: Designed to meet the dimensional, material, and optical requirements specified for fuel dilution testing by Fourier Transform Infrared Spectroscopy.
• Batch-certified IR transmission profile: Each production lot undergoes spectral verification against NIST-traceable reference standards to confirm absorbance uniformity ≤ ±0.003 AU across the diagnostic mid-IR region.
• Chemically inert construction: Polypropylene formulation resists degradation from diesel, gasoline, biodiesel blends (B5–B20), and synthetic turbine oils—ensuring no leaching or extractables that could compromise spectral baselines.
• Integrated barcode labeling: Each vial carries a unique, solvent-resistant 1D barcode compliant with GS1-128 standards, enabling seamless integration with LIMS and automated data traceability per ISO/IEC 17025 requirements.
• Controlled fill volume geometry: Conical base and tapered neck minimize meniscus variability and support consistent pathlength alignment within the FDM6000’s fixed-focus IR cell—reducing inter-vial measurement standard deviation to <1.2% RSD (n=30).

Sample Compatibility & Compliance

The FDM Vial Kit is validated for use with mineral-based, semi-synthetic, and fully synthetic lubricants—including engine oils (API SP/CJ-4), hydraulic fluids (ISO VG 32–68), and gas turbine oils (MIL-PRF-23699). It accommodates samples containing up to 15% v/v fuel dilution without phase separation or wall adhesion artifacts. All vials comply with RoHS Directive 2011/65/EU and REACH Annex XVII restrictions on heavy metals and phthalates. Packaging documentation includes full Certificate of Conformance (CoC) referencing ASTM D7413, ISO 17359:2014 (Condition monitoring — General guidelines), and OEM specifications for Spectro FDM6000 system validation protocols.

Software & Data Management

Vial usage is automatically logged via the FDM6000’s embedded firmware when scanned using the integrated barcode reader. This triggers audit-trail entries in the instrument’s secure database—including timestamp, operator ID, sample ID, and vial serial number—supporting FDA 21 CFR Part 11 electronic record requirements. Spectro’s FluidScan® software (v5.2+) links vial-specific calibration metadata to each measurement session, enabling retrospective recalibration if batch-level transmission drift is detected during periodic IR source verification. Raw spectral files (.spc format) embed vial lot identifiers, ensuring full chain-of-custody traceability in GLP and GMP-regulated facilities.

Applications

• Routine engine oil analysis in commercial fleet maintenance programs to detect abnormal fuel leakage into crankcase oil.
• Condition-based monitoring of marine diesel engines where unburned fuel ingress correlates with injector wear or cylinder liner scoring.
• Verification of fuel-oil separation efficiency in dual-fuel engine lubrication systems operating on LNG/diesel blends.
• Root-cause investigation of viscosity loss in turbine oils exposed to hydrocarbon process leaks.
• Calibration verification and system suitability testing during FDM6000 IQ/OQ/PQ qualification under ISO/IEC 17025 accreditation.

FAQ

Are these vials compatible with other IR spectrometers besides the FDM6000?
Yes—provided the instrument accepts 12 mm OD × 45 mm height cylindrical cells with conical bottoms and supports manual or auto-scan mode in transmission geometry; however, spectral baseline correction algorithms in non-Spectro platforms may require revalidation.
Can the vials be reused after cleaning?
No—these are single-use, disposable components. Reuse introduces risk of cross-contamination, micro-scratching, and irreversible adsorption of high-boiling hydrocarbons, violating ASTM D7413 section 7.2 requirements for clean, virgin containers.
What is the shelf life of an unopened vial kit?
Three years from date of manufacture when stored at 15–25°C and protected from UV exposure; lot-specific expiration dates are printed on the outer packaging and encoded in the barcode.
Is this kit suitable for used oil analysis involving water or glycol contamination?
No—water and glycol produce strong, overlapping IR absorptions that interfere with fuel band quantification; separate sample preparation (e.g., centrifugation, dehydration) is required prior to vial loading.
Does the kit include caps with septa for syringe injection?
Yes—each vial is supplied with a pre-assembled, low-extractable silicone/PTFE septum cap certified for repeated needle puncture without particulate generation or seal failure.
