PULUODY PLD-6010 Medical Infusion Set Particulate Analyzer

Overview

The PULUODY PLD-6010 Medical Infusion Set Particulate Analyzer is a regulatory-grade light obscuration (LO) instrument engineered for quantitative detection and sizing of insoluble particulate matter in parenteral drug products, medical devices, and pharmaceutical process fluids. Based on the industry-proven principle of single-particle optical sensing—where particles suspended in a laminar fluid stream pass through a focused dual-laser narrow-beam detection zone, generating transient light blockage pulses proportional to their equivalent spherical diameter—the PLD-6010 delivers traceable, reproducible particle counts across 1000 programmable size channels from 1 µm to 500 µm (with optional extension to 0.03–3000 µm). Designed explicitly to meet the stringent requirements of pharmacopoeial monographs—including Chinese Pharmacopoeia (ChP) 2020 Edition , United States Pharmacopeia (USP) , , and , European Pharmacopoeia (EP) 10.0, and Japanese Pharmacopoeia (JP) 17—the system supports both routine quality control and advanced filter validation studies, such as infusion set terminal filter efficiency testing and particle removal rate quantification.

Key Features

• 8th-generation dual-laser narrow-beam sensor architecture delivering enhanced signal-to-noise ratio and reduced pulse distortion for improved sizing fidelity at low concentrations.
• Dual-mode precision fluid handling: a calibrated metering piston pump ensures volumetric accuracy (<±1%), while an independent electromagnetic flow control system maintains stable laminar flow during sampling and rinsing cycles (5–150 mL/min sampling; 5–500 mL/min rinse).
• 1000-channel high-resolution analysis engine enabling granular distribution profiling—fully customizable channel definitions support simultaneous compliance with multiple global standards (e.g., ChP 0903’s 10/25 µm thresholds and USP ’s 10/25 µm reporting bins).
• FDA 21 CFR Part 11-compliant software suite (V8.9) featuring five-tier user permission management, electronic signatures, immutable audit trails, automatic data backup/recovery, and power-fail recovery protocols.
• Integrated temperature-controlled fluid path (0–80 °C operational range) suitable for viscous or thermally sensitive formulations including ophthalmic solutions, vaccines, and lyophilized reconstitution media.
• Pre-validated calibration traceability to JJG 1061, ISO 21501-4, and NIST-traceable polystyrene latex standards—supported by accredited third-party metrology institutions including the National Institute of Metrology (Northwest Center) and the Defense Science & Technology Commission Level-1 Particle Measurement Station No. 116.

Sample Compatibility & Compliance

The PLD-6010 is validated for direct analysis of a broad spectrum of pharmaceutical and biopharmaceutical liquids without filtration or dilution: sterile aqueous injectables (solution, concentrate, lyophilized powder reconstitutes), intravenous raw materials, ophthalmic preparations, vaccine suspensions, Water for Injection (WFI), Purified Water (PW), pharmaceutical packaging components (e.g., IV bags, stoppers, tubing per YBB 00272004-2015), and infusion device assemblies (per GB 8368). It further supports cleanroom monitoring, component wear testing (e.g., pump diaphragms, valve seats), and post-filtration challenge studies—including quantitative assessment of terminal filter retention efficiency against defined particle challenge distributions. All measurement protocols align with GLP and GMP documentation expectations, with full data integrity assurance under Annex 11 and ICH Q5A/Q5C frameworks.

Software & Data Management

The embedded V8.9 analytical platform provides bilingual (English/Chinese) touchscreen operation alongside optional wireless keyboard/mouse input. The software enables real-time histogram generation, cumulative distribution plots, Pass/Fail evaluation against user-defined limits (e.g., ChP max. 12 particles ≥10 µm and 2 particles ≥25 µm per mL), and automated report export in PDF, CSV, and XML formats. Audit logs record all user actions—including method edits, result overrides, and calibration events—with time-stamped, non-erasable entries. Electronic signature workflows comply with ALCOA+ principles, and raw data files are cryptographically hashed to prevent tampering. System backups may be scheduled to local drives or network-attached storage, with versioned archive retention configurable per organizational SOP.

Applications

• Pharmaceutical QC labs: Routine batch release testing of injectables, ophthalmics, and biologics per pharmacopoeial mandates.
• Medical device manufacturers: Validation of particulate shedding from IV sets, connectors, filters, and elastomeric components per ISO 8536-4 and GB 8368.
• Water system qualification: Monitoring of WFI, PW, and ultrapure water in pharmaceutical manufacturing facilities per USP and EU GMP Annex 1.
• Semiconductor & electronics: Slurry cleanliness verification (CMP slurries), wafer rinse water, and photoresist carrier fluids per SEMI F63 and ASTM F2275.
• Chemical & specialty materials: Nanoparticle dispersion stability in inks, lubricants, cleaning agents, and functional coatings.
• Food, cosmetics, and filtration R&D: Quantitative assessment of particulate load, filter performance, and formulation robustness.

FAQ

Does the PLD-6010 comply with FDA 21 CFR Part 11 requirements?
Yes. The system implements full electronic record and signature controls—including role-based access, audit trail logging, data immutability, and electronic signature authentication—as verified under internal IQ/OQ protocols aligned with Part 11 Annex A guidance.
Can it measure sub-2 µm particles required for some advanced biologics?
The base configuration detects down to 1 µm per ChP/USP standards. Sub-micron capability (0.03–1 µm) is available via optional sensor module and calibration with ISO 21501-4 compliant reference materials.
Is method transfer supported between laboratories?
Yes. The V8.9 software supports export/import of fully configured test methods—including channel definitions, threshold limits, calibration coefficients, and reporting templates—ensuring analytical consistency across multi-site operations.
What third-party calibration services are available?
PULUODY partners with CNAS-accredited institutions including the Northwest Metrology Testing Center (China National Institute of Metrology) and the Defense科工委 Particle Measurement Station No. 116 for annual verification, uncertainty analysis, and ISO/IEC 17025-compliant calibration certificates.
How is system suitability verified before sample analysis?
Built-in system suitability tests include flow rate verification, background noise assessment, coincidence error evaluation at 1000 p/mL, and reference standard response confirmation using NIST-traceable 10 µm and 25 µm latex spheres per USP Section 3.
