Overview
The WinNano Winner2000ZD is a benchtop laser diffraction particle size analyzer engineered for high-precision, routine wet-dispersion analysis of solid particulates in liquid suspensions. It operates on the principle of Mie scattering theory and Fraunhofer diffraction, with an optimized convergent beam Fourier transform optical architecture that extends angular detection sensitivity—particularly critical for submicron particles down to 0.1 µm. The system integrates a fully enclosed, self-contained wet dispersion module—including ultrasonic deagglomeration (40 kHz, up to 60 W), programmable mechanical stirring (0–3000 rpm), and laminar-flow recirculation (8 L/min)—ensuring homogeneous sample presentation without sedimentation or secondary agglomeration. Automatic optical alignment via a four-phase hybrid stepper motor (positioning resolution ≤1 µm) eliminates manual centering errors and guarantees long-term optical stability across repeated measurements.
Key Features
- Convergent-beam Fourier transform optical design: Eliminates lens aperture limitations, enhancing angular resolution and improving detection fidelity for particles <1 µm.
- Full-ring photodetector array: 76-channel (standard) or 78-channel (ZDE variant) silicon photodiode configuration with azimuthal symmetry for isotropic scattering capture and robust size distribution inversion.
- Unconstrained free-fitting algorithm: Solves the inverse scattering problem without assuming log-normal or Rosin-Rammler distribution models—preserving true multimodal and skewed population structures.
- Patented integrated wet dispersion unit (CN ZL.2010 1 0533181.6): Combines sonication, shear mixing, flow-through circulation, and drain control in a single sealed subsystem—minimizing operator intervention and cross-contamination risk.
- Auto-alignment optical path: Real-time feedback-driven stepper motor positioning ensures continuous laser beam centering on the detector array, reducing inter-run variability.
- Dual operation modes: Manual parameter tuning for method development and fully automated “one-click” measurement mode compliant with GLP documentation workflows.
Sample Compatibility & Compliance
The Winner2000ZD is validated for aqueous and organic suspensions of insoluble or poorly soluble solids—including metal powders, ceramic precursors, pharmaceutical excipients, mineral fillers (e.g., calcium carbonate, kaolin), battery cathode/anode materials (e.g., graphite, LiCoO₂), agrochemical formulations, and nanocomposite slurries. It conforms to ISO 13320:2009 (Particle size analysis — Laser diffraction methods), GB/T 19077–2016 (Chinese national standard equivalent to ISO 13320), and internal WinNano specification Q/0100JWN001–2013. While not FDA 21 CFR Part 11–certified out-of-the-box, its software audit trail, user access control, and electronic signature support can be configured to meet basic GMP/GLP data integrity requirements for regulated laboratories.
Software & Data Management
The proprietary WinNano Particle Analysis Suite (v4.x) provides ISO-compliant reporting templates, batch processing, statistical comparison (t-test, ANOVA), and customizable export (CSV, PDF, XML). Raw scattering intensity data is stored with full metadata—including timestamp, operator ID, instrument serial number, dispersion parameters (sonication duration, stir speed, flow rate), and environmental conditions (ambient temperature logged via onboard sensor). Data files are write-protected post-acquisition; modification history is automatically recorded. Software supports multi-language UI (English, Chinese, Spanish), ASTM E29–22 rounding rules, and D10/D50/D90 confidence interval estimation using bootstrap resampling.
Applications
This analyzer serves quality control and R&D functions across industries requiring reproducible particle size quantification: catalyst synthesis labs monitoring Pd/C or Pt/Al₂O₃ dispersion; battery material producers qualifying SiOₓ anode slurries; pharmaceutical firms characterizing micronized APIs in suspension formulations; ceramic manufacturers optimizing zirconia or alumina feedstock homogeneity; and environmental testing centers analyzing sediment or nanoparticle-spiked water samples. Its 10 mL micro-cell option enables precious-sample analysis—critical for early-stage nanomaterial development where material availability is constrained.
FAQ
What dispersion media are compatible with the Winner2000ZD?
Deionized water, ethanol, isopropanol, and other low-viscosity, low-absorption solvents commonly used in particle characterization. Viscosity should remain below 20 cP to ensure stable laminar flow through the recirculation system.
Can the instrument measure dry powders?
No—the Winner2000ZD is designed exclusively for wet dispersion. Dry powder measurement requires optional pneumatic dispersion accessories not included in this model.
How is calibration verified?
Using NIST-traceable polystyrene latex (PSL) standards (e.g., 10 µm and 100 µm) and silica-based reference materials certified per ISO 13320 Annex B. Calibration verification is performed before each analytical session per internal SOP.
Is remote operation supported?
Yes—via secure TCP/IP connection using WinNano Remote Control Module (sold separately), enabling instrument monitoring and method execution from off-site workstations.
What maintenance is required?
Quarterly cleaning of the flow cell and ultrasonic transducer; annual verification of laser power output and detector dark-current baseline; biannual replacement of circulating pump seals per manufacturer’s service schedule.
