Nano Particle Size Analyzer - DLS Dynamic Light Scattering Particle Sizer - 0.3-10000 nm, ±0.1°C

The Master Science Nano Particle Size Analyzer works on the dynamic light scattering (DLS) principle. A high-performance PMT detector and a high-speed digital correlator follow the fluctuations of light scattered at a fixed angle, the diffusion coefficient is derived from them, and particle diameter and size distribution are then calculated with the Stokes-Einstein equation.

Covering 0.3 nm to 10000 nm, the Master Science Nano Particle Size Analyzer offers fast calculation, high resolution and good repeatability. It is widely used in company product laboratories, research facilities and universities.

Common Problems This Analyzer Solves

Nano-scale sizing is sensitive to conditions that this instrument keeps under control.

• Temperature drift alters viscosity and results:: semiconductor control keeps the sample within ±0.1°C.
• Weak scattering from very small particles:: a PMT detector picks up low light levels.
• Signals change within nanoseconds:: the correlator resolves fluctuations down to 8 ns.
• External interference disturbs the optics:: fibre-based detection has strong anti-interference capability.
