Laser light scattering nanoparticle size analyzer Winner803

laserdynamic light scatteringfor research

Overview
Winner803 uses dynamic light scattering (DLS) and photon correlation spectroscopy to determine nanoparticle size distribution. Based on Brownian motion, the instrument records scattered light fluctuations at a fixed angle, derives diffusion coefficients and calculates particle diameters via the Stokes–Einstein equation. Designed for research institutes, university laboratories, R&D centers and quality control laboratories.

Key Highlights / Advantages

• Dual-wavelength laser with automatic switching for samples with absorbance characteristics.
• DLS and photon correlation processing to extract particle size from photon fluctuation signals.
• High temporal resolution via CR256 digital correlator (resolution down to 8 ns).
• High sensitivity with HAMAMATSU photomultiplier tube (PMT) detector for improved signal-to-noise ratio.
• Fast data acquisition and processing (data throughput up to 162M) using a proprietary CR256 correlator.
• Stable optical path with fibre coupling for enhanced anti-interference performance.
• Precise temperature control using semiconductor regulation (accuracy ±0.1°C).
• Exportable, customizable test reports with standard particle size metrics and distributions.
