Overview
The PULUODY PLD-601PTT Glucose Insoluble Particulate Analyzer is a high-precision optical light-obscuration (LO) particle counter engineered for regulatory-grade particulate quantification in parenteral pharmaceuticals and ultra-pure process liquids. Designed specifically to meet the stringent requirements of pharmacopoeial methods—including Chinese Pharmacopoeia (ChP) 2015 & 2020 Appendix 0903, USP , , and , EP 10.0, and JP 17—the instrument employs an 8th-generation dual-laser narrow-beam sensor architecture to deliver robust discrimination of sub-micron to macroscopic insoluble particles (1–450 µm). Its core measurement principle relies on transient light attenuation caused by particles traversing a precisely collimated laser path; each pulse amplitude correlates directly to particle cross-sectional area, enabling calibrated size binning and absolute count per unit volume. The system is validated for use across sterile drug product release testing, filter integrity verification (e.g., terminal sterilizing-grade filters), extractables/leachables support, and cleanroom fluid monitoring—making it integral to quality control laboratories operating under ICH Q5, Q9, and Q10 frameworks.
Key Features
- 8th-generation dual-laser narrow-beam optical sensor with real-time signal deconvolution for improved resolution at low concentrations and high particle densities
- Dual-mode flow control: precision metering plunger pump (±1% volumetric accuracy) coupled with electromagnetic flow regulation for stable, pulsation-free sampling across 5–150 mL/min range
- 1000-channel high-resolution sizing capability (0.01 µm minimum bin width), supporting user-defined channel configurations compliant with >510 international standards
- FDA 21 CFR Part 11-compliant software suite (V8.9) featuring five-tier role-based access control, electronic signatures, immutable audit trails, and automated data backup/recovery
- Integrated thermal management system enabling stable operation from 0–80 °C sample temperature and 0–50 °C ambient conditions
- Modular calibration traceability to JJG 1061–2010, ISO 21501-4, and NIST-traceable polystyrene latex standards (PSL)
- Embedded 10.1″ capacitive touchscreen interface with optional wireless keyboard/mouse support for flexible lab integration
Sample Compatibility & Compliance
The PLD-601PTT is validated for direct analysis of a broad spectrum of liquid matrices critical to pharmaceutical and biotechnology manufacturing. These include aqueous glucose solutions, sterile injectables (solution, lyophilized powder, and concentrated formulations), ophthalmic preparations, vaccines, Water for Injection (WFI), Purified Water (PW), and pharmaceutical-grade excipients. It also supports testing of medical device components (e.g., IV sets per YBB00272004–2015 and GB 8368), packaging materials, and filtration systems—enabling quantitative assessment of filter retention efficiency and particulate shedding. All operational protocols align with GMP Annex 1, WHO Technical Report Series No. 961, and EU Guidelines on Sterile Medicinal Products. Method equivalence is documented against ISO 21501-4 (calibration), ISO 11171 (flow rate validation), and ISO 4406 (contamination coding), ensuring global regulatory acceptance.
Software & Data Management
The V8.9 analysis platform provides fully auditable data handling in accordance with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Each measurement session generates encrypted metadata logs—including operator ID, timestamp, instrument configuration, calibration status, environmental parameters, and raw pulse data—retained for ≥30 years per configurable policy. The system supports automated report generation in PDF/A-2 format compliant with eCTD submission requirements. Data export options include CSV, XML, and SQL-compatible dumps for LIMS integration. Remote diagnostics, firmware updates, and method library synchronization are enabled via secure TLS 1.2–encrypted LAN/WiFi connectivity. Full 21 CFR Part 11 compliance includes digital signature workflows, electronic record locking, and granular permission assignment down to individual test parameters.

- Chemical & Cosmetics: Nanomaterial dispersion stability, pigment suspension homogeneity, and preservative efficacy screening
FAQ
Does the PLD-601PTT comply with FDA 21 CFR Part 11 for electronic records and signatures?
Yes—its V8.9 software implements full Part 11 functionality including audit trail logging, electronic signatures with biometric or token-based authentication, and role-based permissions with enforced separation of duties.
Can the instrument be calibrated to traceable national standards?
Yes—calibration is supported using NIST-traceable PSL standards or certified reference materials per JJG 1061–2010 and ISO 21501-4, with documentation provided by accredited third-party metrology institutes including NWMS (National Northwest Metrology Center) and DFKW (No. 116 Defense Science & Technology Metrology Station).
Is method customization available for non-pharmacopoeial applications?
Yes—users may define custom particle size thresholds, channel groupings, reporting templates, and pass/fail criteria aligned with internal SOPs or industry-specific guidelines such as SEMI F63 for electronic chemicals.
What maintenance intervals are recommended for routine operation?
Daily system flush with filtered solvent; weekly optical path inspection; quarterly sensor alignment verification; annual full metrological recalibration recommended—supported by PULUODY’s certified service network and ISO/IEC 17025-accredited partners.
