Overview
The Spectra Invent HX-PC1805 Liquid Particle Contamination Analyzer is a precision-engineered instrument designed for quantitative assessment of particulate contamination in hydraulic fluids, lubricating oils, turbine oils, aviation fuels, and other industrial liquids. It operates on the principle of light extinction (also known as optical blockage or single-particle optical sensing—SPOS), where particles suspended in a laminar liquid flow pass through a precisely defined sensing zone illuminated by a collimated light source. Each particle generates a transient reduction in transmitted light intensity proportional to its cross-sectional area, enabling real-time, size-resolved counting and sizing across standardized particle diameter bins (e.g., ≥4 µm(c), ≥6 µm(c), ≥14 µm(c), ≥21 µm(c), ≥38 µm(c), ≥70 µm(c)). The system complies with core international standards including ISO 4406:2017, ISO 11171:2016 (for calibration), NAS 1638, SAE AS4059F, and ASTM D7647/D7648 for fluid cleanliness classification and reporting.
Key Features
- Integrated dual-pressure (positive/negative) sampling module enabling controlled aspiration and pressurized delivery — supports degassing of viscous or volatile samples and ensures consistent flow rates across viscosity ranges from 2 to 400 cSt.
- Onboard pressure transducer continuously monitors chamber pressure; user-configurable pressure thresholds trigger automatic system hold or shutdown to prevent over-pressurization and ensure operator and instrument safety.
- Dedicated internal air purification unit with HEPA-grade filtration (≥99.97% @ 0.3 µm) maintains ISO Class 5 (Class 100) clean-air environment within the optical detection chamber, eliminating airborne interference during measurement.
- Multi-point factory-calibrated reference curves preloaded into firmware — compatible with ISO, NAS, SAE, and military-standard particle count protocols without manual curve interpolation or external software mapping.
- Robust stainless-steel fluid path components with wetted materials certified for chemical compatibility with hydrocarbon-based and synthetic lubricants (per ASTM D471 and ISO 1817).
Sample Compatibility & Compliance
The HX-PC1805 accommodates sample volumes from 5 mL to 100 mL per analysis cycle, with programmable flow rates (0.5–25 mL/min) optimized for both low-viscosity solvents and high-viscosity gear oils. It supports direct analysis of unfiltered, undiluted fluids — no solvent dilution required for most routine applications. All measurement outputs are traceable to NIST-traceable PSL (polystyrene latex) calibration standards. The instrument meets essential requirements for GLP-compliant laboratories: full audit trail logging (user actions, method parameters, calibration events), electronic signature support, and secure data storage with timestamped raw count histograms. Optional configuration enables 21 CFR Part 11 compliance via password-protected user roles, biometric or token-based authentication, and immutable record archiving.
Software & Data Management
The bundled SpectraClean™ Analysis Suite (v3.2+) provides intuitive instrument control, real-time visualization of particle distribution histograms, and automated generation of ISO 4406 code reports. Data export formats include CSV, PDF, XML, and .pca (proprietary binary archive). Software modules support statistical process control (SPC) charting (X-bar/R, CUSUM), trend analysis across multiple sampling points, and integration with LIMS platforms via ASTM E1384-compliant HL7 or ODBC interfaces. Firmware updates are delivered via encrypted USB key or authenticated HTTPS download, with version rollback capability and SHA-256 integrity verification.
Applications
- Condition monitoring of hydraulic systems in aerospace ground support equipment and wind turbine pitch control units.
- Pre-commissioning verification of cleanliness in turbine lube oil systems prior to startup (per ISO 4406 Class 15/13/10 or stricter OEM specifications).
- Quality assurance testing of new lubricants and greases per API RP 12R1 and ISO 12181-2.
- Root-cause analysis of component wear in diesel engine oil using trending of >14 µm(c) particle counts over service intervals.
- Validation of filter performance (beta-ratio testing) in accordance with ISO 16889 and ISO 11171.
FAQ
What particle size ranges does the HX-PC1805 measure?
The instrument measures particles from 4 µm(c) to 70 µm(c) in accordance with ISO 4406:2017, using calibrated optical thresholds corresponding to equivalent circular diameter (ECD) under light extinction detection.
Can it analyze water-glycol or phosphate-ester fluids?
Yes — with optional chemically resistant flow cell (model HX-FC-PE) and validated cleaning protocol, the system supports non-hydrocarbon fluids meeting ASTM D6792 conductivity limits (<500 µS/cm).
Is calibration traceable to national standards?
All factory calibrations are performed using NIST-traceable PSL reference particles (Thermo Fisher Count-Cal® series) and verified against ISO 11171:2016 procedural requirements.
Does the system support automated batch reporting for fleet-wide oil analysis programs?
Yes — SpectraClean™ includes template-driven report generation with configurable metadata fields (equipment ID, location, sampling date, analyst ID) and scheduled export to network shares or cloud storage endpoints.
How often must the optical sensor be cleaned or recalibrated?
Under normal operation (≤50 samples/week), optical path cleaning is recommended every 200 analyses; full recalibration is required annually or after any sensor replacement, per ISO 17025 internal quality procedures.
