Overview
The Brookfield 1140 Water Separation Index Analyzer is a precision-engineered electromechanical instrument designed for standardized evaluation of water separation performance in aviation turbine fuels and other hydrocarbon-based distillates. It operates on the principle of turbidimetric quantification following controlled emulsification and coalescence processes, enabling objective assessment of fuel’s ability to release entrained water under simulated filtration conditions. This capability is critical for detecting surfactant contamination—commonly introduced via lubricants, biocides, or cleaning agents—which inhibits efficient water removal in aircraft fuel systems. Poor water separation directly correlates with increased risk of microbial growth (e.g., Pseudomonas fluorescens, Cladosporium resinae), tank corrosion, filter plugging, and potential engine flameout. The 1140 supports four distinct ASTM test methods in a single platform: D3948 (water separation index for jet fuels), D7224 (modified water separation index using alternate coalescer media), D7261 (water separation index for synthetic hydrocarbon fuels), and D4860 (free water and particulate content by turbidity). Its architecture integrates programmable mechanical agitation, calibrated flow control, and a high-stability optical turbidimeter with NIST-traceable calibration reference.
Key Features
- Four-in-one test platform compliant with ASTM D3948, D7224, D7261, and D4860—eliminating need for multiple dedicated instruments
- Integrated turbidimeter with dual-range optical detection (0–100 NTU scale), factory-calibrated against formazin standards
- Programmable magnetic stirrer delivering reproducible shear history during emulsion generation (±1 rpm accuracy)
- Dedicated “Six-Pack” consumable kits—pre-packaged, vacuum-sealed coalescer/filter assemblies containing ASTM-specified glass fiber or polymeric media
- Modular sample handling system with borosilicate glass vials and disposable syringes to prevent cross-contamination
- Robust industrial-grade housing with ESD-safe enclosure and IP54-rated protection for laboratory and field-deployable use
Sample Compatibility & Compliance
The 1140 is validated for use with Jet A, Jet A-1, JP-5, JP-8, TS-1, and other kerosene-type aviation fuels meeting ASTM D1655 and DEF STAN 91-91 specifications. It also accommodates diesel fuel oils (ASTM D975), biodiesel blends (ASTM D7467), and synthetic paraffinic kerosenes (SPK) per ASTM D7566 Annex A2. All test procedures conform to current editions of referenced ASTM standards, with full traceability to ISO/IEC 17025-accredited calibration protocols. The instrument meets electromagnetic compatibility requirements per IEC 61326-1 and safety compliance per UL 61010-1. Documentation includes full validation reports supporting GLP and GMP environments, including audit-ready electronic logs compliant with FDA 21 CFR Part 11 when used with optional data export modules.
Software & Data Management
While the base 1140 operates as a standalone benchtop unit with analog turbidity readout and manual timing controls, optional USB-enabled firmware upgrade enables direct data capture into CSV or Excel-compatible formats. Timestamped test records include operator ID, ambient temperature/humidity (via external sensor input), coalescer lot number, sample identification, and raw turbidity values before/after processing. Audit trails support revision-controlled storage and are compatible with LIMS integration via standard ODBC drivers. Software modules include automated pass/fail flagging per specification thresholds (e.g., D3948 pass limit ≤ 20), statistical process control (SPC) charting, and trending reports aligned with ISO 9001 quality management requirements.
Applications
- Refinery final product release testing for aviation fuel batches prior to dispatch
- In-service fuel monitoring at military airbases and commercial airline hubs
- Surfactant interference studies during additive package development
- Coalescer media qualification and lifecycle assessment for fuel filtration systems
- Root cause analysis of recurrent filter plugging or microbial contamination incidents
- Third-party certification testing accredited under ISO/IEC 17025 scope
FAQ
What ASTM standards does the 1140 support?
It fully implements ASTM D3948, D7224, D7261, and D4860 for water separation index and free water/particulate quantification.
Is the turbidimeter calibrated to NIST standards?
Yes—the optical system is factory-calibrated using certified formazin standards traceable to NIST SRM 2102.
Can the 1140 be used for non-aviation fuels?
Yes, it is routinely applied to diesel, marine distillates, and synthetic hydrocarbons where water separation performance is a key quality parameter.
Are coalescer cartridges supplied with the instrument?
No—coalescers are provided as consumable “Six-Pack” kits (vacuum-sealed, lot-numbered), sold separately to ensure method fidelity and shelf-life integrity.
Does the 1140 require external PC connectivity for routine operation?
No—standalone operation is fully functional; PC connectivity is optional and used only for enhanced data logging and reporting.
